What is physical weathering?
Nadusha1986 [10]

What is physical weathering?: Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering.

How do trees break down solid rock?: When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel. This process can also break up bricks on buildings. Chemical weathering decomposes or decays rocks and minerals.

What causes the most common type of physical weathering?: Physical Weathering. Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. ... There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

what percent does water expand?: 9%

How does water break down apart a rock?: Flowing water can move rocks, causing them to rub together and wear down into rounded shapes. When plants grow in cracks in a rock, their roots can widen the cracks and force the rock apart. Rainwater fills small cracks in a rock. As the water freezes, it expands, widening the cracks and splitting apart the rock.

P.s. You could've just googled these.
