You hear about a magnitude 8. 0 earthquake on the news. Someone says "That doesn't sound too bad. An 8. 0 is just one more than the 7. 0 we had here last year. " Explain why that's not the right way


to think about the moment magnitude scale

Answers

Answer 1

You hear about a magnitude 8.0 earthquake on the news, and someone says it doesn't sound too bad since it's just one more than the 7.0 earthquake from last year. However, this is not the right way to think about the moment magnitude scale.

The moment magnitude scale is a logarithmic scale, meaning that each whole number increase represents a tenfold increase in the amplitude of ground motion and approximately 31.6 times more energy release. So, a magnitude 8.0 earthquake is not just one point more than a magnitude 7.0 earthquake, but rather ten times stronger in terms of ground motion and about 31.6 times more powerful in terms of energy release.

In conclusion, it is important to understand that the moment magnitude scale is logarithmic, and an increase in magnitude represents a significant increase in the earthquake's intensity and energy release. Therefore, an 8.0 magnitude earthquake is significantly more powerful than a 7.0 magnitude earthquake.

Quartz and feldspar make up the majority of the light-coloured, acidic igneous rock known as granite, which contains over 50% of each.

These two minerals can be seen with the unaided eye in hand specimens and are lighter in colour and larger in size. There is also a negligible amount of mica, amphibole, and other minerals The granite content of the continental crust is high. The coarser minerals found in this rock suggest that they cooled from the molten rock particles at a considerably slower rate. The stable cratons and the deep basement rocks make up the majority of these granites. Even though they are invisible to the unaided eye, plagioclase and pyroxene predominate in mafic rocks, with olivine appearing less frequently. Mafic minerals (mostly hornblende, pyroxene, and/or biotite) and felsic minerals (primarily plagioclase) are generally evenly distributed in mixtures to form intermediate rocks. Quartz is scarce or non-existent.

Which type of fog is produced when air is lifted over a topographic barrier?.

Answers

The type of fog produced when air is lifted over a topographic barrier is called orographic fog.

The orographic fog is caused when air is forced to ascend on the windward side of mountains because of the physical barrier offered by the hills and mountains. As the air rises, it cools and reaches its dew point temperature; this causes condensation to take place, leading to the formation of orographic fog.

The dew point temperature is the point where the air is saturated with water vapor, and any additional water vapor condenses into liquid water or ice. This occurs since the temperature at which the air becomes fully saturated varies depending on the quantity of water vapor in the air.At the mountaintop, the condensed water droplets either evaporate or continue to form cloud droplets, leading to the formation of clouds.

fossilized Archaeopteryx a) In which era did it appear? b) Why is it important as a fossil that "links" change between different groups of organisms? c) Using this recreation of Archeopteryx, what evidence can you see that relates to this connection?

Answers

Archaeopteryx first appeared in the Late Jurassic Period which is a geological era of the Mesozoic Era that lasted from about 163.5 to 145.5 million years ago. The fossilized remains of Archaeopteryx were discovered in 1861 in the region of Solnhofen in Germany.

Archaeopteryx is important as a fossil that "links" change between different groups of organisms because it has characteristics of both birds and reptiles, suggesting that birds may have evolved from reptiles. Archaeopteryx is considered a transitional form between non-avian dinosaurs and birds, possessing both reptilian and avian features.

It has a mix of features found in modern birds, such as feathers and wings, as well as features found in non-avian dinosaurs, such as teeth and a long, bony tail. This makes it a valuable specimen for scientists studying the evolution of birds.

Using the recreation of Archaeopteryx, some of the evidence that relates to the connection between birds and reptiles include: Feathers: Archaeopteryx had feathers, which are a characteristic feature of birds. However, these feathers were not as specialized as those of modern birds. They were asymmetrical and lacked hooks, barbs, and a central shaft.

This suggests that feathers may have evolved for purposes other than flight, such as insulation or display.Bird-like skull: Archaeopteryx had a bird-like skull, with a short snout and large eyes. However, it also had a reptilian feature - teeth in its jaws.

This is unlike modern birds, which have a beak instead of teeth. Reptilian tail: Archaeopteryx had a long, bony tail that was similar to that of non-avian dinosaurs. However, its tail was shorter and more flexible than that of its dinosaur ancestors. This suggests that the tail may have played a role in flight control, but was not used for balance while walking on the ground.

Answers

3.4. The shape of the river valley in the upper course is typically V-shaped or steep-sided.

3.5. Evidence that indicates a graded profile in the longitudinal profile includes the presence of meanders and floodplains.

A river can maintain its graded longitudinal profile through river rejuvenation, adjusting its profile in response to external changes.

In the upper course of a river, the shape of the river valley is typically V-shaped or steep-sided. This is because in the upper course, the river is characterized by high energy and vertical erosion. The river erodes downwards, cutting through the landscape and forming a narrow valley with steep sides.A graded profile refers to a longitudinal profile of a river that shows a smooth, gentle slope from the upper course to the lower course. Evidence indicating a graded profile includes the presence of meanders, floodplains, and a gradual decrease in gradient downstream. This indicates that the river has achieved a balance between erosion and deposition, resulting in a stable equilibrium.A river can maintain its graded longitudinal profile through a process called river rejuvenation. This occurs when tectonic uplift or changes in base level rejuvenate the river, causing it to undergo renewed vertical erosion and adjust its profile. The river responds by downcutting and eroding the landscape to establish a new graded profile in response to the changes in its external conditions. This process allows the river to maintain its equilibrium and achieve a graded longitudinal profile over time.

the intergovernmental panel on climate change reported in 2007 that atmospheric carbon dioxide levels will nearly double by the end of this century. if this happens, what will be the atmospheric concentration of carbon dioxide?

Answers

The atmospheric concentration of carbon dioxide is projected to reach approximately 560 parts per million (ppm) by the end of this century.

In 2007, the Intergovernmental Panel on Climate Change (IPCC) predicted that by the end of the century, atmospheric carbon dioxide levels would have roughly doubled. The global climate could change as a result of this growth in atmospheric carbon dioxide in a number of ways, including increasing temperatures, sea level rise, and more severe extreme weather events.

The IPCC report estimates that if atmospheric carbon dioxide concentrations double by the end of this century, the atmosphere's carbon dioxide concentration will be around 560 parts per million (ppm). This is more than double the 280 ppm pre-industrial concentration and may have major climate-related consequences. It is crucial for nations to put effective climate policies into place and lower their greenhouse gas emissions in order to lessen the consequences of climate change and lower atmospheric carbon dioxide levels.
