If it is smaller or fractured when compared to an earlier time period

Water is the substance that has the greatest effect on the rate of weathering of rock. Water can seep into cracks in rock, freeze and expand, causing the rock to break apart. Water can also chemically react with minerals in the rock, leading to chemical weathering.
Chemical weathering
The two main types of weathering are mechanical (physical) weathering and chemical weathering. Mechanical weathering involves the physical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of rock materials through chemical reactions.
Unloading contributes to weathering by relieving pressure on rock layers, which can cause expansion and fracturing of the rock. This can lead to the breaking off of outer layers of rock, increasing surface area exposed to weathering processes such as erosion and chemical weathering.
Two ways to tell that a rock has been weathered are a change in color or texture, and the presence of fractures or cracks due to expansion and contraction caused by weathering processes. Additionally, the flaking or crumbling of the rock's surface may indicate weathering.
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.
The effect of weathering is to reduce the volume of the igneous rock.
Weathering may change the rock into many shapes.
By weathering either by physical or chemical weathering.
It is water weathering
by weathering
It is the process of weathering.
Any and all rock can be changed into sediment by weathering and erosion.
Ice freezing in a crack of a rock is considered weathering.
The process of breaking down of rocks and minerals on the surface is known as rock weathering.
