Why do middle latitude dry regions exist?
Why do middle-latitude dry regions exist, and what role do mountains play in their existence? They are in the middle of landmasses and thus are distant from oceans , which are sources of moisture. Middle-latitude deserts at the leeward side of mountains receive air that has already lost moisture.
How does wind move sand?
Even very strong winds can’t lift the sand any higher than three feet above the ground. As the wind blows, it lifts small sand grains a few inches off the ground, then drops them . When they hit the ground, they bump into other sand grains and cause them to jump up and be caught by the wind.
