The crack in the sidewalk is an example of physical weathering, specifically a type of weathering known as frost wedging or freeze-thaw weathering. This occurs when water seeps into cracks in rocks or concrete, freezes, expands, and eventually causes the material to break apart.

Over time how might the grass growing up through a crack in a sidewalk affect the sidewalk Use the terms and ldquophysical weathering and rdquo and and ldquochemical weathering and rdquo in your answe?
The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
When a tree cracks a sidewalk is it weathering?
Yes, when a tree root cracks a sidewalk it is a form of mechanical weathering. The growth of the tree exerts pressure on the sidewalk causing it to break and crack over time.
Is cracks on a sidewalk next to a tree physical or chemical weathering?
Cracks on a sidewalk next to a tree are primarily caused by physical weathering. The tree roots grow and expand, exerting pressure on the sidewalk, which eventually causes it to crack. This is a mechanical process rather than a chemical one.
Is mechanical weathering a crack in the sidewalk?
Mechanical weathering refers to the physical breakdown of rocks into smaller fragments without changing their chemical composition. It can indeed contribute to cracks in a sidewalk over time, especially in areas with temperature variations leading to freezing and thawing cycles.
What term best identifies the type of weathering represented by a?
The term that best identifies the type of weathering represented by a salt crystal growing in a crack in a rock is mechanical weathering. This occurs when physical forces, such as the growth of salt crystals, exert pressure on rocks causing them to break apart or crack.

Do you remember when crack was a hole in the sidewalk?
I remember when crack was a hole in the sidewalk. That was back when coke was a soft drink.

When The most common type of mechanical weathering occurs?
water freezes in a crack in a rock
Does salt on a sidewalk cause mechanical or chemical weathering to the sidewalk?
Chemical, the sodium in the salt exchanges with calcium in the concrete. The chemical products are all water soluble and the surface of the sidewalk washes away.
Is ice freezing in a crack of a rock erosion or weathering?
Ice freezing in a crack of a rock is considered weathering.
What is the superstition about stepping in the crack of the sidewalk?
Stepping in a crack on the sidewalk is a superstition heard by many people around the world. If one steps on a crack on the side walk, it would break their mother's back.
Is ice freezing in a crack of a rock considered weathering or erosion?
Ice freezing in a crack of a rock is considered weathering.
What did the sidewalk say to the jackhammer?
"You crack me up!" Hahaha.
