You will have to cross 4 national borders if you went from Tallinn to Bucharest.

Political boundaries exist along borders. Cities, towns, counties, states, and provinces are divided by them. The territory under the jurisdiction of one governing body is delineated by a border. Only within its own borders may a region's government enact and execute laws. Borders evolve with time.

Warfare, colonialism, or agreement between the political entities that occupy those territories are all ways that political borders can be constructed; the process of establishing such agreements is known as boundary delimitation.

The percentage increase in mango imports into the UK between 2012 and 2016 is 73.68.  The value of goods and services that are exported and imported by countries that engage in international trade is referred to as the export-import ratio.

Given

Year                  Export

2012                     38

2013                      47

2014                      47

2015                      56

2016                      66

Required to calculate the percentage increase in export from 2012 to 2016 =?

Increase Percentage = Export in 2016 - Export in 2012 *100 / export in 2012

                                  = 66 - 38 * 100 / 38

                                  = 73.68%

A country gains when its export-import ratio improves because it can increase its exports and decrease its imports.

Thus, the percentage increase in mango imports into the UK between 2012 and 2016 is 73.68.

Scandinavia shares a similar latitude with Europe and North America.

Scandinavia is located in the Northern Hemisphere, specifically in the high-latitude region known as the boreal zone. This region is characterized by long, cold winters and short summers, as well as a relatively low level of solar radiation.

The countries of Norway, Sweden, and Denmark are located at a similar latitude as other northern regions in Europe, such as Finland and Russia, as well as regions in North America, like Alaska and Canada. Because of this similar latitude, these regions experience similar weather patterns and have similar ecosystems.

For example, boreal forests, tundra and glaciers are common in these regions. However, it's important to note that the proximity of the sea, the presence of the Gulf Stream and the local topography can affect the weather and temperature conditions, making some areas milder than others.

Answer: Today, glacial deposits formed during the Permo-Carboniferous glaciation (about 300 million years ago) are found in Antarctica, Africa, South America, India and Australia. If the continents haven’t moved, then this would suggest an ice sheet extended from the south pole to the equator at this time - which is unlikely as the UK at this time was also close to the equator and has extensive coal and limestone deposits. If the continents of the southern hemisphere are re-assembled near the south pole, then the Permo-Carboniferous ice sheet assumes a much more reasonable size.

More evidence comes from glacial striations – scratches on the bedrock made by blocks of rock embedded in the ice as the glacier moves. These show the direction of the glacier, and suggest the ice flowed from a single central point.

The piece of Wegener’s evidence for continental drift most closely relates to the North Pole Glacier are fossils.

Continental drift is the theory that the Earth's continents have shifted relative to one another during geologic time, giving the appearance of "drifting" across the ocean floor.

Wegener supported his continental drift theory with fossil data. These species' fossils have been discovered in distant lands. Grooves and rock deposits left by prehistoric glaciers can still be observed today on many continents around the equator.

Glacial striations, which are scratches on the bedrock caused by chunks of granite stuck in the ice as the glacier advances, provide more evidence. These depict the glacier's orientation and imply that the ice flowed from a single focal location.

As a result, Fossils are the element of Wegener's evidence for continental drift that is most directly related to the North Pole Glacier.

Among the given options, B) The solar and lunar gravitational forces are about the same magnitude is true regarding the gravitational forces affecting Earth.

The gravitational forces affecting Earth primarily come from the Sun and the Moon. While both the Sun and the Moon exert gravitational forces on Earth, their magnitudes are not equal. However, option B states that the solar and lunar gravitational forces are about the same magnitude, which is not correct.In reality, option C) The solar force is about twice that of the Moon is closer to the truth. The Sun's gravitational force on Earth is significantly stronger than that of the Moon. The Sun's mass is about 27 million times greater than the Moon's mass, resulting in a much greater gravitational pull.

Option A) The lunar force is about twice that of the Sun is incorrect. The Moon's gravitational force on Earth is approximately 180 times weaker than that of the Sun.Option D) The gravitational forces of each vary depending upon seasons on Earth is also not accurate. The gravitational forces exerted by the Sun and the Moon on Earth do not significantly vary with the changing seasons. However, other factors such as the tilt of Earth's axis do cause variations in seasons, but they are not directly related to gravitational forces.

Total distance covered by group A = 4.22 miles

Total distance covered by group B = 3.92 miles

So, Group A is farther from camp in comparative to other Group B.

What is Direction Sense?

Direction sense ability is  to find one's way around easily in a new place a good/poor sense of direction.

Here, Distance travel together = 5 miles.

After changing their direction distance covered by them = 1.5 miles.

Group A turns 33⁰ towards north

So, total distance covered by group A = 1.5 + 5 × sin 33⁰

                                                                = 4.22 miles

Group B turns 61⁰ towards south.

Similarly, distance covered by group B = 1.5 + 5 × cos 61⁰

                                                                 = 3.92 miles

Thus, Group A is farther from camp in comparative to other Group B.
