Weathering is a process by which rocks and minerals are gradually broken down into smaller and smaller particles.
Weathering of rocks is caused by chemical and mechanical means. Slightly acidic rainwater can react with rock surfaces, dissolving them over time. Rocks can also be affected by organic sources of chemical reactants. Heat from the sun can cause differences in temperature between the surface and the interior of a rock which can cause a loosening of the surface called exfoliation. Liquid water penetrates cracks in the rocks surface where it can freeze and expand, opening up the cracks for further attack in tandem with acidic rainwater. Plant root growth can also cause cracks to further expand, making them more vulnerable to frost expansion and chemical attack. Underlying rock which is exposed due to erosion of the overlying rock becomes free of the pressure it was previously exposed to, causing the rock to expand and break apart. Other means of weathering include the expansion of crystallizing salts that have been taken in by a rock surface, expansion due to the absorption of water, and hydraulic action from crashing waves on seashore rock formations.
Atmospheric Erosion
The Sun's heat causes surface rocks to expand and fracture, and moisture can evaporate. Rain dissolves amospheric gases to form acids that combine with minerals in surface layers. Water can also freeze at night or in winter, expanding cracks and carrying away smaller rocks and dust. Wind and water also carry small particles that can impact and erode rocks, and carry away loose soil.
Biological Erosion
Many plants secrete acids in their roots that dissolve the minerals they need. Root structures also enlarge cracks seeking water. Animals crush surface rocks and deposit organic materials that interact with minerals. Related, but not technically erosion, is the manmade removal of minerals and rocks from on and below the Earth.

Weathering is the process over time of rocks breaking apart. It can be caused from rivers flowing quickly or when water freezes in the small crevices of rocks.

all done :)
Water, ice, and plant growth.
The weather.
Wind, water, and rocks
like snowing,rainy,and storming
No, they don't. Rocks don't cause weathering at all. They are the things which get weathered.
Weathering and rain and ice are the cause of the breaking down of rocks
no
Tornadoes have a negligible contribution, if any, to the weathering of rocks. However, they can cause localized soil erosion.
How fast it weathers
No, they don't. Rocks don't cause weathering at all. They are the things which get weathered.
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.

weathering results in the disintegration of rocks on a large scale. then these rocks break-up and forms soil and the soil forms the soil profile.
When animals walk across them it can cause weathering.
