Frost action: Water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart. Temperature changes: Daily heating and cooling of rocks cause them to expand and contract, eventually leading to cracks and breakage.
The three main causes of weathering are physical weathering (e.g. wind, water, and ice), chemical weathering (e.g. oxidation and hydrolysis), and biological weathering (e.g. plant roots and burrowing animals). These processes break down rocks and minerals into smaller particles over time.
There are two main causes of mechanical weathering: frost action and abrasion. Frost action occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart. Abrasion happens when rocks are physically broken down by forces like wind, water, or glaciers.
The seven main causes of weathering are thermal expansion and contraction, ice wedging, plant roots, abrasion, animal activity, dissolution, and oxidation. These processes contribute to the breakdown and erosion of rocks and minerals over time.
Two important causes of chemical weathering are oxidation, which occurs when minerals are exposed to oxygen and chemically react with it, and hydrolysis, which happens when minerals interact with water molecules and break down into new compounds. These processes can weaken rocks and minerals, leading to their eventual breakdown and decomposition.
acid rain, pollution
Well the two MOST common causes would be water and oxygen... hope this helped :D
Cliff Fallinmg down rock breaking
the causes of weathering are water, wind, and ice. -your welcome.
If you want to draw something of mechanical weathering like me then i got the idea for you draw a rock with cracks and a concrete house with no roof at the top mechanical weathering

WEATHERING and EROSION
