Answer:
Crystal size
Explanation:
The most obvious difference between extrusive rocks and intrusive rocks is crystal size. Because extrusive rocks cool quickly, they only have time to form very small crystals such as basalt or none at all. On the other hand, intrusive rocks grow larger crystals because they take longer to cool.
Answer: it has to do with the earth. The earth rotates and spins around the sun. Therefore the sun “rises and sets” (we can see it) for around 12 hours
Explanation:
Answer:
There is a higher concentration of people who live in the northern hemisphere than the southern hemisphere.
Explanation:
A is not correct because the equatorial region is not densely populated, but it is actually sparsely populated.
B is not correct because the southern hemisphere doesn't have a higher concetration of people than the northern hemisphere.
C is not correct because if that was the case the population density would have been the highest either on the Equator or the poles, and that is not the case at all.
D is not correct because the population density is related to the concept of agricultural production.
E is correct because the northern hemisphere has a higher concentration of population than the southern hemisphere, and this is largely due to the fact that there is much more land on the northern hemisphere, thus a much larger area where there are suitable conditions for living.
Answer:
about 1,200 miles
Explanation:
Red Sea, Arabic Al-Baḥr Al-Aḥmar, narrow strip of water extending southeastward from Suez, Egypt, for about 1,200 miles (1,930 km) to the Bab el-Mandeb Strait, which connects with the Gulf of Aden and thence with the Arabian Sea.
Answer:
Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.
Explanation:
"The result is a topographic depression where the oceanic plate comes in contact with the overriding plate, which may be either oceanic or continental. If the overriding plate is oceanic, an island arc develops. The trench forms an arc in plan view, and islands with explosive volcanoes develop on the overriding plate. If the overriding plate is continental, a marginal trench forms where the topographic depression appears to follow the outline of the continental margin. Explosive volcanoes are found there too"
