Answer:
a. short grasses and cacti
Explanation:
The semi-arid and arid areas in the western part of the United States are harsh environments, and only specialized plants for these conditions can survive. The climate is hot and dry, the precipitation very low, and the soil is poor. The plants that survive in these places have adapted well to survive with very little water, to manage to extract water from the air, to preserve it, and being able to sustain very high temperatures. The short grasses are the dominant plants int he semi arid regions. They do not require rich soil, nor lot of water, so they manage to survive on the bear minimum that is available. The trademark plants of the arid areas are the cacti. The cacti are able to store large amounts of water in them, have very long roots, are able to extract water from the air through their needles, and also have skin that doesn't allow any water to come out of it.

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.
Oceanic crust is more dense which makes it subduct and continental crust is less dense which makes it override the oceanic crust during subduction
The Himalayas Mountains provide a natural barrier between India and the rest of Asia. I hope this helps!!!
