Lesson 7 - Describe radiometric dating and discuss three prerequisites that must be met in order to obtain a reliable radiometric date on a granite batholith. What are the various methods of radiometric dating that may be used

Answers

Answer 1

Answer:

RADIOMETRIC DATING can also be seen as the way of determining the particular time in which materials were been formed by studying the decay of the radioactive isotopes that exist in the material, which is why RADIOMETRIC DATING is reliable because the rates of decay for many types of isotopes do not vary.

3 PREREQUISITE

1. The rate of decay must remain constant and must not vary.

2. The amount of parent and daughter must as well remain completely precise.

3. Lastly the granite would as well have to have stayed a closed system for the whlle period of time following when it was created

METHOD OF RADIOMETRIC DATING

1. The potassium argon dating

2.Uranium lead dating

Explanation:

REDIOACTIVE DATING can be defined as the method in abundance ratio of a radioactive isotope is been compared to a reference isotope in order to help determine the actual age of a material and this is done measuring the decay of radioactive atoms to effectively determine the age of a rock sample.

In other word RADIOMETRIC DATING can also be seen as the way of determining the particular time in which materials were been formed by studying the decay of the radioactive isotopes that exist in the material, which is why RADIOMETRIC DATING is reliable because the rates of decay for many types of isotopes do not vary.

Therefore in order for to obtained a reliable radiometric date for a granite batholith, their are three prerequisites which must be followed and they are :

1. The rate of decay must remain constant and must not vary.

2. The amount of parent and daughter must as well remain completely precise.

3. Lastly the granite would as well have to have stayed a closed system for the whlle period of time following when it was created .

Some of the various methods of RADIOMETRIC DATING include;

1. The potassium argon dating

2.Uranium lead dating

Below is the formula for RADIOMETRIC DATING

log F = (N/H)log(1/2)

Where F is the fraction remaining

N is the number of years

H is the half life.

In order to determine the fraction remaining we have to know the particular amount which is now present as well as the amount which was present at the time when the mineral was been formed.

migration begins at the area called​

Answers

Migration begins at the area called the point of origin.

What is the starting point for migration?

The point of origin is the initial location from where a migratory journey begins. It serves as the starting point for individuals or groups of organisms as they embark on their seasonal or long-distance movements. This area is typically characterized by favorable conditions, such as abundant resources or suitable breeding grounds that trigger the need for migration.

It acts as a launching pad for migratory routes and plays a crucial role in determining the direction and timing of the migration. The point of origin can vary on species or context, ranging from specific breeding sites for birds to specific regions for human migration patterns.

Deposition is the wearing away of land
masses.
C. Deposition always occurs slowly, over

D. Weathering and erosion allow for the
formation of fossils. Deposition is the
breaking up of fossils.

Answers

Weathering and erosion allow for the formation of fossils. Deposition is the breaking up of fossils. Thus, option D is the correct option.

Rocks and minerals on the surface of the Earth weather or dissolve. Erosion is the transportation or movement of the weathered material, while deposition is the depositing of the weathered material. The deposition is the act of silt being dropped by gravity, wind, water, or ice.

Weathering causes sediment to be produced, erosion causes it to be taken away, and deposition causes it to be dumped in a new site. Any process that reduces rocks to tiny fragments is known as weathering. Weathering and the loss of sediments are two aspects of erosion. The deposition is the act of erosional agents discharging sediment.

Déscribe some differences between the fauna of African, Australian, South American, and Euroasian savanna’s

Answers

Answer:

Explanation:

Savanna-like ecosystems were present at high latitudes in North America during much of the Neogene. Present-day African savannas, like the Serengeti, have been proposed to be modern analogs of these paleosavannas, particularly those from the middle Miocene of the Great Plains region of the United States. Both these extant and extinct savannas contain a preponderance of artiodactyl (even-toed ungulate) species; however, the taxonomic composition of each fauna is different. While present-day African savannas are dominated by ruminants (primarily bovids), the Neogene savannas of North America were dominated by a diversity of both camelid and non-bovid ruminant families. This study provides a quantitative test of the similarity of the artiodactyl faunas of the North American Neogene paleosavannas to those of the modern-day African savannas. A correspondence analysis of ecomorphological features revealed considerable overlap between modern and fossil faunas. The morphospace occupation of the extinct North American ruminants falls within that of the African bovids. Some of the extinct camelids also fall within this same morphospace, but many do not, perhaps indicating an environmental difference such as greater aridity in Neogene North America. The diversity and disparity of artiodactyl faunas through the Neogene of North America changed along with changing temperatures and precipitation regimes. The taxonomic and ecomorphological diversity of the Serengeti ruminant fauna is statistically comparable to those North American paleofaunas occurring during or immediately after the Middle Miocene Climatic Optimum (MMCO), but the later, more depauperate faunas are no longer comparable. This study quantitatively analyzes artiodactyl communities as they changed with the cooling and drying trend seen during the Neogene.

Convective lifting occurs when air heated at the earth's surface rises in the form of thermal currents or bubbles. Widespread ascent results from the interaction of air masses, or the movement of a cold air mass forcing warm air to rise ahead of it. Mechanical (or frictional) turbulence occurs when the air flow is deformed into a series of eddies as it moves over the earth's surface. All of the above.

The answer is "All of the above".

Explanation:

Moist air may be elevated to form a cloud in different ways, as follows:

Electrical or frictional turbulence allowing air to deform when Eddie moves over the crust of the ground.If two continental plates meet as well as the cold air forces the hot air to just go up but so clouds form. Through merging or vertical lifting.The orographic raising was its term given to the air process which rises to the cloud when an obstacle is met.As sunlight heats its earth's surface and warms that air in contact with the air, creating a heat transfer throughout the mass of air but instead rises in the form of heat currents or bursts.

A government which holds total power over a country, affecting both the economy & society, is know as a_______state.

Answers

A government that holds total power over a country, affecting both the economy and society, is known as an authoritarian state.

In an authoritarian state, power is concentrated in the hands of a single individual or a small group of individuals who exercise control over all aspects of governance and decision-making. This type of government often suppresses political dissent, restricts civil liberties, and maintains strict control over the economy.

In an authoritarian state, the government's influence extends beyond political matters and into the economic and social realms. The state exerts control over industries, trade, and resources, often implementing central planning and state ownership of key sectors. Individual freedoms and rights may be curtailed, with limited political participation and freedom of expression. Censorship and surveillance are commonly used to maintain control and suppress opposition.

Authoritarian states can have varying degrees of control, ranging from mild to extreme, but they all share the common characteristic of centralized power and limited individual freedoms. These states often prioritize stability and control over individual liberties and democratic processes, leading to significant challenges in achieving political pluralism, economic diversification, and social progress.

A 10-25 P B Resistant Quartzite Shale 25-45' Shale Resistant Sandstone C >45 Leas Resistent Strata Resistent Strate [Source 2.4.1 Identify the feature labelled A. 2.4.2 Differentiate between features labelled A and C. 2.4.3 Classify the slopes P and Q​

Answers

Answer:

2.4.1 What do you call a rock that doesn't erode easily? A resistant stratum or a resistant layer. This is a hard or tough layer of rock that can withstand the forces of erosion better than the other layers around it. For example, the feature labelled A is made of quartzite, which is a rock that used to be sandstone but got transformed by heat and pressure. Quartzite is so hard that it can scratch glass and it is mostly made of quartz.

2.4.2 How can you tell the difference between feature A and feature C? Well, they are not the same in how they were formed, what they are made of and how fast they erode. Feature A is a resistant layer of quartzite, which is a metamorphic rock that changed from sandstone because of heat and pressure. Feature C is a less resistant stratum or a less resistant layer. This is a soft or crumbly layer of rock that gets worn away faster than the other layers around it. For example, the feature labelled C is made of shale, which is a rock that came from mud that had clay and quartz in it. Shale is so soft that it can break into thin layers.

2.4.3 Why do slopes P and Q look different? Because they are concave slopes and convex slopes, respectively. A concave slope is a slope that bends inwards or downwards, like a bowl. A convex slope is a slope that bends outwards or upwards, like a dome. Concave slopes usually form on resistant layers that erode slower than the layers below them, creating a ledge or a cliff. Convex slopes usually form on less resistant layers that erode faster than the layers above them, creating a smooth slope or a valley.

The summary of napoleons conquest from the point of view of one of his soldiers

Answers

Answer:

The below explanation is a good summary of Napoleon's conquest from the point of view of one of his soldiers.

Explanation:

As a soldier in Napoleon's army, I witnessed firsthand the incredible military campaigns that led to his conquests. Under his leadership, we marched through Europe and won victories against powerful enemies like Austria, Prussia, and Russia.

Napoleon's tactics and strategies were innovative and effective. He utilized fast-moving infantry and cavalry to outmaneuver his opponents, and he was a master of artillery. His ability to inspire his soldiers and keep them disciplined was unmatched.

However, the cost of war was high. I saw many of my fellow soldiers fall in battle, and the toll on civilians and their homes was devastating. Despite the glory of victory, there were also moments of fear and uncertainty as we faced superior forces and harsh conditions.

Despite the challenges, I remained loyal to Napoleon and believed in his vision for a united Europe. His military conquests brought about significant changes, such as the spread of the Napoleonic Code and the modernization of government and society in conquered territories. As a soldier, I was proud to serve under his leadership and contribute to his remarkable legacy.

To write a summary of Napoleon's conquest from the point of view of one of his soldiers, you must do consistent research of the period, in historical documents and books, to generate reliability in your text.

What were Napoleon Bonaparte's conquest?

In his military and political career, Napoleon had several achievements, such as:

why are UAV stereo image taken with very high degree of overlap in remote sensing?​

Answers

Answer:

Ensuring contiguity and to obtain three dimensional vision

Explanation:

In each aerial photograph, nearly 60% of the places depicted in the adjacent photo is included. This is done for ensuring contiguity and to obtain three dimensional vision with the help of stereoscope. This is called overlap in aerial photographs.

UAV stereo images are taken with a very high degree of overlap in remote sensing because it allows for the creation of anaglyphic images. Anaglyphic images are created by combining two images taken from slightly different angles, which creates a 3D effect when viewed with special glasses. By having a high degree of overlap between the two images, it allows for a more accurate and detailed anaglyphic image to be created. This is important in remote sensing because it allows for more accurate analysis and interpretation of the data.

Answers

Answer:

The correct answer is B. Both India and Pakistan struggle with language diversity, making it difficult for the government to communicate effectively and educate its population.

Explanation:

Both India and Pakistan are multicultural nations, emerged as a result of different peoples of the Indica peninsula united around a common religion (Hinduism in India and Islam in Pakistan). Therefore, given the cultural differences in non-religious aspects that each country has, and the high population of both nations (1,400,000,000 people in India and 215,000,000 in Pakistan, being the first and fifth most populous nations respectively), both countries tend to create of diverse cultural subgroups that maintain a common language and their own idiosyncrasy.

Thus, India has as official languages ​​English and Hindi, but some 15 other languages ​​are spoken within its territory, among which Bengali, Punjabi, Sanskrit, Tamil and Urdu, among others, stand out.

In turn, Pakistan has English and Urdu as its official languages, but Punjabi, Pashto, Sindhi and Balochi, among others, are also spoken.

Thus, it is clear that both countries do not have a language integrity that allows clear and effective communication among the entire population, which is a clear limitation for education and social stability in both countries.
