What are two causes of physical weathering?

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.


What are the three main causes of weathering?

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.


How many main causes cause mechanical weathering?

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.


What are the 7 main causes of weathering?

There are many causes of weathering. Some of the main causes of weathering are:Thermal stressFrost weatheringOcean wavesPressure releaseSalt-crystal growthBiological effects


What is the two important causes of chemical weathering?

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.
