What are some examples of machanical weathering?
3 examples are- 1.ice wedging - when water gets into cracks, freezes and expands 2.roots-while they grow, they push rocks aside that later break. 3.animals- when they dig underground, they push rocks aside causing them to break
How do living organism contribute to the weathering of rocks?
Living organisms can weather rock by plant root wedging, secretion of acids and enzymes, burrowing, walking, building dams, and any other activity that results in the breaking down of rock.
Which part of the plant often break rocks apart?
THe root is the part of the plant that often break rocks apart.The root is also the part that is almost always underground.There are two main types of roots tap root and fibrous roots.Hope this helps you!
What type of weathering causes root wedging?
Biological hydraulic weathering.
What are two ways rocks are mechanically weathered?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
What is root wedging?
tree roots break down rocks as they grow in cracks
What are some differences between ice wedging and plant root growth in a rock?
in ice wedging, water gets into cracks in rocks and freezes. As it turns into ice, it expands. this cause the rock to be pushed off. In plant root growth, the roots get into the cracks and grow bigger. this also causes the rock to break off. I hope I somehow helped you :)
How is frost wedging similar to root wedging?
they are both a type of physical weathering and both may break rock through a crack or a crevice. Frost wedging is when water enters a crack and may freeze causing the crack to expand because when water freezes it contrasts and expands. Root wedging is when a plant grows through a crack causing the roots to expand and break through the rock. -michael yap
Is root wedging a form of chemical weathering?
No. Root wedging is a form of mechanical weathering.
What are 2 similarities between ice wedging and plant root growth in rocks?
hey the other person is a mean person so im here to improve on this answer :D. 1 similarity is that the plant growth and the ice wedge both break apart the rock causing the rock to expand and eventually cut into half. Hope this helped you!
What are the two important causes of mechanical weathering?
Temperature changes make rocks expand and contract and it is one of the important cause of mechanical weathering. Water abrasion is the other important cause. Wind and moving water cause rocks to rub against each other and the rocks could well break into smaller pieces.

What is the definition of mechanical weather?
Mechanical (or physical) weathering is where physical forces (abrasion, exfoliation, frost action, root wedging) break the rock into smaller pieces but the composition of the rock is fundamentally unchanged. in other terms: Mechanical weathering is the process of erosion where larger rocks are broken down into smaller rocks without changing any of its chemical nature. The rocks are basically crashed by physical breakdown, rather than chemical. :)
How do roots break rocks?
By expansion of existing fractures via root growth.
What living thing can break down rocks?
Plants are known to intrude their roots into cracks and crevices. The growing root is able to separate layers of stone as it grows.
