Wind is the primary agent of erosion in arid regions due to the lack of water and vegetation.

Weathering is the process of breaking down rocks into smaller particles due to exposure to atmospheric conditions.

Transportation is the process of moving sediment from one location to another by wind, water, ice, or gravity.

Biological weathering is the process of breaking down rocks by the action of living organisms, such as plants and animals.

Deposition is the process of accumulating sediment in a particular location after it has been transported by wind, water, ice, or gravity.

Chemical weathering is the process of breaking down rocks by the action of water, which can dissolve minerals and cause rocks to disintegrate.

Erosion is the process of wearing away of the Earth's surface by the action of wind, water, ice, or gravity.

Physical weathering is the process of breaking down rocks by the action of temperature changes, which can cause rocks to expand and contract, leading to cracking and disintegration.

Wind erosion is the process of moving sediment from one location to another by the action of wind.

Physical weathering is the process of breaking down rocks by the action of ice, which can cause rocks to freeze and thaw, leading to cracking and disintegration.

Water erosion is the process of moving sediment from one location to another by the action of water.

Physical weathering is the process of breaking down rocks by the action of gravity, which can cause rocks to fall and break apart.

Ice erosion is the process of moving sediment from one location to another by the action of ice.

Biological weathering is the process of breaking down rocks by the action of plants and animals, such as the growth of roots and the burrowing of animals.

Gravity erosion is the process of moving sediment from one location to another by the action of gravity.
