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.

How weathering change rocks?
how does weathering change rock
Is weathering the process by which rocks on or near earths surface break down and change?
The change undergone is physical only. The definition of weathering is the wearing away of rocks in situ. Weathering causes the rocks to "break down", but mostly not to chemically change (the exception being limestone in acid rain).
Which type of weathering causes the mineral composition of rocks to change?
mechanical weathering
Is weathering rocks chemical or physical change?
physical
How can weathering mechanically and chemically change the earth?
Mechanical weathering or physical weathering changes the earth by causing rocks to crumble. Mechanical weathering has the same effect when rocks heat up and cool down
Does chemical weathering change the chemicals in rocks?
Chemical weathering affects rocks rain, wind or ice . Chemical weathering is the process that changes the composition ( the inside) of rocks on the earth surface.
Does mechanical weathering change a rocks chemicals?
No, not at all. Chemical weathering changes the molecular composition of minerals, but mechanical weathering only changes its shape or outward appearance.

What kinds of rocks are caused of weathering?
Metamorphic rocks change into sediments through weathering
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.
