Weathering occurs because of contraction and expansion of rocks due to change in weather. Contraction occurs because of cooling of rocks at night and expansion occurs due heating of rocks in the morning.

Mechanical weathering occurs due to physical processes such as temperature changes, frost action, and abrasion. These processes break down rocks into smaller pieces without changing their chemical composition.

Well, the earth does not like hard corners. Even the planets are sperical. Spherical shapes have less wind resistance and a sphere is the most efficient shape. When Wind, Water, Gravity, Ice, Animals, and Plants knock off pieces or particles of rocks, it's just helping the rock achieve the most wind resistant shape.

Mechanical weathering occurs when rocks are broken down and there is no change in the nature of the rocks. Physical force causes the rocks to break, not chemical breakdown.

In which type of climate does mechanical weathering occur?

Mechanical weathering can occur in any type of climate, but it is more prominent in cold and dry climates where freeze-thaw cycles and temperature changes can break down rocks.


What type of climate causes mechanical weathering to occur at a greater rate?

A cold and freeze-thaw climate causes mechanical weathering to occur at a greater rate. The expansion of water as it freezes and thaws can break apart rock and mineral structures, leading to increased rates of mechanical weathering in these conditions.

What is a cause of mechanical weathering?

Weathering may occur through the actions of water, air, plants, animals and various chemicals. Mechanical weathering is the breaking down of rocks into smaller pieces without changing the composition of the minerals in the rock


Which is most common in the desert mechanical or chemical weathering?

Chemical weathering is more common in deserts, as the dry conditions limit the amount of mechanical weathering that can occur. Chemical weathering processes such as oxidation, hydration, and dissolution are more prevalent in desert environments where water is scarce.


What Are two kind of weathering?

Does a cold climate help mechanical weathering?

No. mechanical weathering is the breaking and separating of rock or other materials. In order for mechanical weathering to occur you need water or some kind of mass movement. the only erosional agent which works with mechanical weathering are creep and solifluction, but mechanical weathering itself cannot happen because if it is too cold the frost wedging cannot happen becasue the water would freeze in contact and would not expand
