Exposure to sunlight can affect the color of some minerals that are present in rock. Because conditions of temperature and pressure change as a body of rock nears the surface, fracturing may occur and minerals which were formed in a different environment can undergo a chemical transformation into new minerals with a different appearance. Rain and groundwater can cause dissolution or oxidation of minerals in rock as well, altering their surface appearance. The main effect of weathering is in the size of a body of rock. They become smaller and typically more rounded.

What does pysical weathering mean?
Physical weathering refers to the process by which rocks and minerals are broken down into smaller pieces through mechanical forces such as frost shattering, root wedging, and abrasion. This type of weathering does not change the chemical composition of the rock, only its physical appearance.
How would a beach change if rocks stopped weathering?
If rocks stopped weathering, the process responsible for their breakdown and erosion would cease. This would result in a buildup of larger rocks on the beach, giving it a more rugged and rocky appearance. The beach may also experience less sand production over time since weathering is a key factor in creating sand from rocks.
What are three weathering forces that help change rocks into soil?
Three weathering forces that help change rocks into soil are physical weathering, chemical weathering, and biological weathering. Physical weathering involves the breaking down of rocks into smaller pieces through processes like freezing and thawing. Chemical weathering involves the chemical alteration of minerals within rocks, while biological weathering involves the action of plants, animals, and microorganisms breaking down rocks.
Is weathering of rocks reversible or irreversible change?
Weathering of rocks is usually an irreversible change. Once rocks are broken down or altered by processes like mechanical weathering (such as frost wedging) or chemical weathering (such as oxidation), it is typically difficult to reverse these changes and return the rock to its original state.
Which type of weathering causes the mineral composition of rocks to change?
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
What is different between physical weathering and chemical weathering?
Physical weathering is breaking down of rocks by weather that does not change their chemical components. Chemical weathering is weathering that breaks rocks down by a chemical change.
Does chemical weathering change the chemicals in rocks?
Yes, chemical weathering alters the minerals and compounds in rocks by breaking them down through processes like dissolution and oxidation. These changes can result in the formation of new minerals and compounds as the original rock material is chemically transformed over time.
Is weathering of rocks a physical change?
yes
How do rocks change colors?
by weathering ************ Igneous rock is initially formed when lava cools down. After which weathering would begin.
