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:
Regions with a higher amount of rainfall are those of equatorial regions and those of the low rainfall are polar areas.
Explanation:
- The regions in the tropics and the subtropics receive a significant amount of rainfall while the place at the places receives only 10 inches f rainfall and regions are dry annually with rain occurring only in summer.
- The tropical areas are those that surround the earth equator and are found 23 degrees north and south. As the sun is usually in direct contact and this region comprise of 40% of the surface area and 35% of the earth's landmass. And remains warm to hot and moist year-round.
- These regions are characterized by wet season and thus have most of the cyclonic activity through the year and this impacts the global distribution of water as the movement of the warm and cold water stakes form these regions, along with the variation in salinity.
C. Nuclear to be honest, I don’t know, but I think this is the answer.
Yes aids had done more harm than good. The reason why because people in Africa didn't have aids and when aids started to spread around the whole world the Africa gotten so sick they started to die.
Hawaii faces challenges in surmounting distances because mainly due to the fact that is is so far away from any other land form. It also has frequent small earthquakes.
