I believe you are looking for the word "metamorphism".
Rock composition refers to the weight percentages (wt%) of minerals contained in the rock.
minerals inside the rock determine the rocks composition
This refers to what constitute the rock;What the rock is made of.The chemical constituents of the rock.
Chemical Changes
Water and air
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
Weathering and erosion would alter the shape of a rock, as would the application of stress possibly combined with high(er) temperature conditions.
the product of weathering issand clay and rock fragments
Chemical Changes
Water and air
it undergoes transformation into another rock.
it undergoes transformation into another rock.
When fluids such as water combine with rock, the composition of the rock changes, which lowers the melting point of the rock enough to melt it.
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
When magma changes the composition of existing rock.
Chemical change not a physical. A CHEMICAL CHANGE
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
chemical. it changes the actual composition of the rock. :)
It is most similar to the composition of the rock basalt.
