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: Physical maps use color most dramatically to show changes in elevation. A palette of greens often displays elevations.

Answer:
The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.
Explanation:
It is 4.5 billion years that Earth has been formed and there have been changes since then. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
