Pressure causes mechanical weathering by exerting force on rocks, leading to stress and cracks in the rock structure. Over time, the pressure causes the rocks to break down into smaller pieces. This process is known as stress release weathering.
Pressure release weathering occurs when overlying rocks are eroded, reducing the pressure on underlying rocks. This decrease in pressure can cause the rocks to expand and crack, leading to physical weathering processes like exfoliation or sheeting. The release of pressure allows the rocks to expand and break apart, resulting in the gradual breakdown of the rock material.
Yes, plant roots can cause mechanical weathering by exerting pressure on rocks as they grow and expand, leading to the breakdown of the rock material. This process is known as root wedging and can contribute to the disintegration of rocks over time.
Air can cause mechanical weathering through a process called freeze-thaw weathering. When water enters cracks in rocks and freezes, it expands and exerts pressure on the rock, causing it to break apart. Additionally, air can also cause chemical weathering by reacting with certain minerals in rocks, leading to their decomposition and eventual breakdown.
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.
The type of weathering that causes Ice Wedging is Mechanical/ Physical Weathering.
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of rocks.

Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
Pressure on them is released, which can cause pressure-release mechanical weathering. Exposure of an uplifted rock to the surface will fully expose the rock to the effects of mechanical and chemical weathering--basically a rock rot.
No, acids cause chemical weathering.
It is a cause of both.
The type of weathering that causes Ice Wedging is Mechanical/ Physical Weathering.
Temperature does not directly exert pressure on rocks to cause physical weathering. While temperature changes can play a role in physical weathering through processes like freeze-thaw cycles, it is not exerting pressure in the same way as factors like water or root growth.
Unloading contributes to weathering by relieving pressure on rock layers, which can cause expansion and fracturing of the rock. This can lead to the breaking off of outer layers of rock, increasing surface area exposed to weathering processes such as erosion and chemical weathering.
