Why do cold currents cause deserts?
They are caused by cold ocean currents, which run along the coast.
They cool the air and make it harder for the air to hold moisture.
Most moisture falls as rain before it reaches the land, eg the Namib Desert in Africa.
The air here is much drier than on the coast..
How do plants survive in cold deserts?
Tundra plants grow very slowly and have bright-colored leaves to absorb more heat from the sunlight. The slow growth helps them store most of their nutrients during photosynthesis and enables them to survive the winter so they can grow again in the summer.
Can deserts occur in cold temperatures?
Cold winter deserts are also known as semi-arid deserts. They have long, dry summers and cold winters with low rain or snowfall. In the United States, the Great Basin, the Colorado Plateau, and the Red Desert are all cold winter deserts.
How are deserts formed?
Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods.
