Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
Answer:
Africa appears much bigger than the other landmasses on the Peters map projection.
Explanation:
There are numerous projection maps. All of them have some advantages and some disadvantages. One of those map projections in the Peters map projection or Gal-Peters map projection. This map projection's biggest problem is that it stretches certain parts of the world, some horizontally, some vertically.
On this map projection, Africa looks much bigger than it is, and it is comparable with the size of Asia even though Asia is much bigger in reality. The reason for this is that on the Peters map projection a vertical stretching occurrs around the Equator, and since the Equator passes around the middle of Africa the effect is the biggest at this landmass.
They are close to the equator, another reason is because of the tropical maritime location, temperature changes throughout the region are generally small.
