chemical weathering
a rock would have a lower rate of weathering when it has more surface area exposed to weathering.
how does weathering change rock
chemical weathering is when a chemical reacts with a rock to brake down a rock.
The igneous rock must be exposed to weathering, whether it be chemical weathering, or mechanical weathering.
Water causes the greatest amount of weathering, especially flowing water. Water is scarce in deserts.
The main form of weathering in a desert is decomposition.
No, desert pavement is caused by wind which is physical weathering.
Mechanical weathering; as distinct from chemical weathering; occurs when the surface of a rock (say) is mechanically abraded. Such as the grits of a river wear away the bedrock. The aeolian sands in the desert will sculpt exposed rock ribs. A glacier will gouge the surface away by grinding the bedrock with boulders, stones, and grit entrained in the ice mass. This type of weathering produces vast quantities of rock flour. Much of the volume of a glacial valley has been turned into rock flour.

The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.

Weathering may change the rock into many shapes.
By weathering either by physical or chemical weathering.
The effect of weathering is to reduce the volume of the igneous rock.
Clastic sedimentary rock is the usual type of rock formed from the products of rock weathering.
