When water freezes and becomes into ice, it expands. Imagine this inside the crack of a rock. Evidently the crack will only enlarge too. After freezing and thawing so many times bits of the rock break off.
Plants can cause both mechanical and chemical weathering.
Mechanical weathering occurs when roots grow and cause the rock to break (just like the roots that crack the sidewalk).
Chemical weathering occurs when roots release chemicals, like acid, which then break down the rocks.

Growing plants can cause both physical and chemical biological weathering. An example of physical (mechanical) biological weathering would be the growth of plant roots in rock crevices which pry the rock apart. Chemical biological weathering would be the production of acids by certain plants which cause a chemical change in a rock's surface chemistry.
Plant and roots cause weathering when the roots spread inside the rock causing it to push apart. The growth loosens and breaks ok pieces of the rock or mountain. - raegand
Their roots grow deep into cracks in rock where water collects. As they grow, roots become thicker and longer, slowly exerting pressure and wedging rock apart.
Trees weather rocks by their roots growing in small crevices, the root grows and sometimes it is strong enough to split the rock. this is also called Root Wedging.
Plants can break rock to pieces from roots growing in cracks of the rock. Plants can also help preserve landforms by preventing erosion by wind or water.
by water
Chemical weathering breaks down rocks
No it doesn't because weathering causes rocks to break down not build up.
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
chemical weathering
The physical weathering agents are basically the water and wind. But the rocks decay mostly because of wind. Wind blows continuously for ages and the rocks that stand in the way get decayed in the long run.
they cause it by their roots growing into rocks and breaking up the rocks. After the rocks have been broken up by trees and plants' roots, water and air will wash it away, and eventually dissolve it.
No, they don't. Rocks don't cause weathering at all. They are the things which get weathered.
their roots open cracks in the rocks further allowing water in, that can then freeze and cause more weathering
Weathering and rain and ice are the cause of the breaking down of rocks
no
Chemical weathering breaks down rocks
flowing water
No it doesn't because weathering causes rocks to break down not build up.
The movement of the waves.
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Erosion and weathering will cause rocks to become rounded.
Tornadoes have a negligible contribution, if any, to the weathering of rocks. However, they can cause localized soil erosion.
