The topography of the seafloor gives us a nice clue about the seafloor spreading. This can be seen in the highest of the underwater features. The mid-ocean ridge is the highest. It is the place where the magma comes out, cools off, and constantly creates new rocks, or rather crust. As we move further away from the mid-ocean ridge, we will notice that the sea mounds are getting smaller and smaller, but also more rounded, or flatter. This is an evidence of the erosion by the water. As the water erodes the crust, it loses on height, thus becomes less pointy, and more rounded or flatter. As we move even further away we will see that there's no more sea mounds, but it is only the old crust that is predominantly flat, which of course has been caused by the millions of years of erosion by the water. This was actually the first thing that has been noticed and that gave a clue to the scientists that maybe the seafloor is spreading, and with the further examinations of it, it turned out to be true.
B) The Red Sea
C) The Nile River
D) The Gulf of Suez
Answer:
C) The Nile River
Explanation:
Of the physical features listed, the one that MOST LIKELY influenced the early settlement of the major population centers of Egypt is the Nile River. If you look closely at the map, you will notice that almost every major settlement in the country is located along the Nile River or its delta.
b.-predict weather patterns
c.-analyze population patterns
d.-keep count of populations in specific areas
Answer:
The correct answer is a caldera.
Explanation:
A caldera is one of the most catastrophic volcanoes that exist.
The way they are formed is unique, since it has the shape of an inverse volcano.
They come to be seen as a great depression because a very large magma chamber is accumulated under the ground because of the gases they contain inside, which generate very high pressures.
Cracks are formed to give way to the escape for these gases which are formed from the magma chamber to the surface.
When this pressure can be released the chamber sinks and finally reveals the final shape of the caldera.
