Which of the following is NOT a cause of mechanical weathering?
Temperature changes, such as freezing and thawing, is NOT a cause of mechanical weathering.
true or fale the freezing and thawing of rocks cracks and breaks rock. this is a mechanical type of weathering?
True. The freezing and thawing of water in cracks and pores of rocks exerts pressure that can cause rocks to crack and break apart. This is known as frost wedging and is a type of mechanical weathering.
Do gravity and ice cause mechanical weathering?
Yes, gravity can cause mechanical weathering through processes like mass wasting, where gravity causes rocks and debris to move downhill. Ice can also cause mechanical weathering through frost wedging, where repeated freezing and thawing of water in cracks and crevices causes rocks to break apart.
What type of weathering can ice wedging cause?
The type of weathering that causes Ice Wedging is Mechanical/ Physical Weathering.
What does not cause mechanical weathering?
Chemical weathering, such as the reaction of rock with acids or oxidation, does not cause mechanical weathering. Mechanical weathering involves physical processes like freezing and thawing, abrasion, and root growth that break rocks into smaller pieces without altering their composition.

What cause mechanical weathering?
Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion

What 2 processes cause weathering?
Mechanical weathering breaks rocks into smaller pieces through physical forces like freezing and thawing, root growth, and abrasion. Chemical weathering alters the composition of rocks through processes like oxidation, hydration, and dissolving by acids.
What is the cycle of freezing and thawing in the cracks of rocks called?
It is called frost heave, frost wedging, and freeze/thaw cycle, an example of mechanical weathering. Cracks formed in rocks by the pressure of freezing allow water to penetrate further, and enlarge the crack when that water freezes, gradually reducing the size of the rock body.
How does thawing and freezing of water cause weather?
by the coldness of freezing and the warmness of thawing
What is it called when water freezes in cracks?
When water freezes in cracks, it expands and can cause the crack to widen, leading to a process known as freeze-thaw weathering. This process is a form of mechanical weathering, where the repeated freezing and thawing of water weakens the rock and causes it to break apart.
What are the forces that cause weathering?
Weathering is primarily caused by three main forces: mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering occurs when rocks are broken down into smaller pieces through physical processes such as freezing and thawing. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation and hydrolysis. Biological weathering is caused by living organisms, which can break down rocks by their growth, burrowing, or through chemical processes.
Would lightning striking a rock be considered mechanical weathering?
No, lightning striking a rock would not be considered mechanical weathering. Mechanical weathering involves physical processes like freezing and thawing, plant roots breaking apart rocks, or abrasion from wind or water. Lightning would not directly cause physical breakdown of the rock's structure.
