Becasue the sand is light to pick up and carry, the wind takes it allong with it, and then the sand bashes into the rocks. These minute particles wear down, so instead of it being a few particles bashing in, it is millions. Because of the high number, the wind erodes rock much quicker.
Yes. Many deserts have rocks in them (called hamada deserts). Large rocks in the deserts are in very unusual shapes due to the erosion of the sand and the wind. After years of sandstorms finally the rocks will crumple and turn into sand themselves.
In the desert, there are few plants, and those plants that do grow have shallow root systems. This lack of plant cover leaves the desert vulnerable to erosion by water because there is very little holding the sediment together. This means that when the sediments become impregnated with water, they are more likely to break away from lower sediments and slide downhill (a landslide). Additionally, this lack of plant material to hold sediments in place enables water to quickly sweep sediments away.
Hot subtropical deserts and polar deserts are extreme. Subtropical deserts are generally very hot while polar deserts are very cold.
Ice can be a very effective agent of erosion, particularly in environments with cold temperatures where freezing and thawing cycles occur. Glaciers, for example, can erode large sections of land as they move over the landscape. However, the effectiveness of erosion also depends on factors such as the specific geology of the area, climate, and the amount of time available for erosion processes to take place.
No, the largest desert in the world is Antarctica, which is obviously very cold. Many deserts sit on high plains and get very cold and snow in the winter months.
Deserts are classified as either hot or cold deserts. Some cold deserts may get quite hot in the summer but are very cold in the winter.
Yes, deserts have winter. Some deserts can be very cold in winter even if summers are hot. Some deserts are quite mild in winter.
A mature stream causes more erosion than a young stream, due to the pure fact that theres more curve in a mature stream causing the sediments to shift more frequently.
Yes, very windy.
No the desert is very dry.
Most deserts are hot during the day.Deserts can be very cold at night.Some deserts are extremely cold during the day and night though.
Yes, Africa has some very large deserts, including the Sahara and the Kalahari.
