heat and extreme pressure. also water freezing and melting.
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
weathering and plant growth growing through and eventually causing a crack in the rock
Water goes into small cracks in the rocks and then freezes. Water expands as it freezes and the expansion pushes outwards on the crack in the rock making it bigger. Eventually this process causes the rock to crack and flake apart
If there is water in the gap, it will freeze. As water expands when it freezes, the crack will be opened wider. This process is called freeze-thaw. Hope that helped!
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.

weathering and plant growth growing through and eventually causing a crack in the rock
Yes, tree roots can make rocks crack through a process called physical weathering. As roots grow, they can exert pressure on surrounding rocks, causing them to crack or break apart. Over time, this can contribute to the breakdown of rocks into smaller pieces.
Plants are the organisms which have roots and can crack rocks
The agent in mechanical weathering where the sun or forest fire causes rocks to crack is thermal expansion and contraction. This process occurs when rocks are exposed to heat from the sun or a fire, causing them to expand and contract at different rates, leading to cracks and eventual breakdown.
Metamorphism is the process where existing rocks are changed by heat, pressure, or fluids. This process causes the minerals in the rocks to rearrange and form new crystals, creating metamorphic rocks.

Carbon dioxide in the atmosphere dissolves in rainwater to form a weak carbonic acid. This acid can react with minerals in rocks, such as limestone, to break them down through a process called carbonation. This chemical weathering process causes the rocks to erode and eventually form new minerals.
Yes, freezing can cause rocks to crack. When water enters the small crevices in rocks and freezes, it expands, putting pressure on the rock and potentially causing it to crack or break apart. This process, known as frost wedging, is a common form of mechanical weathering.
in the daytime the suns heat expands rocks.and in the night it contracts. this causes the rocks to crack and eventually breakdown which foorms soil
Oxidation is the process that causes rocks to weather to a reddish color. This occurs when iron-bearing minerals in the rocks react with oxygen in the presence of water, leading to the formation of iron oxide, which is commonly known as rust and gives the rocks a reddish hue.
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of rocks.
