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.
Explanation:
minerals- is a naturally occuring inorganic solid with a chemical composition and crystalline structure.
rocks- is aggregate of more minerals some rocks are predominantly composed minerals.
Answer:
latitude; direction
Explanation:
Folowing the lalitude of the Earth we observe that the sun’s rays are more intense at the equator and they become less intense as we aproach the poles. At the same time this intensity fluctuates during the seasons due to the Earth's tilted axis (23.5 degree angle), this makes that the hemisphere that is closer to the sun receives more sunlight than the opposing hemisphere.
