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.
The best example is their amazing system of roads. The Incas built roads across the length and width of their empire. To create routes through steep mountain ranges, they carved staircases and gouged tunnels out of rock. They also built suspension bridges over rivers.

Answer:
The coast is a climate on its own.
Explanation:
If there is a comparison between a location with a coast near it, there will always be a climate difference. If the coast happens to be thee Pacific Coast, it is typically colder and more wet due to a lot more rain than more inland cities, but since the Pacific Ocean is colder than the Atlantic, it is not as muggy and humid as the East Coast.
If the coastal town is on the Atlantic Ocean Coastline, it will be more humid, where the air feels heavy and it will be hotter in general due to the heat from the Atlantic Ocean.
