Is dissolution a type of chemical weathering that breaks down rocks by absorbing water?
Yes
Why do cracks in a rock get larger because water has frozen in them?
Weathering is the process which breaks rocks into smaller bits. This is one type of weatheringPhysical weathering is a physical action which breaks up rocks : An example of this is called freeze-thaw weathering when water gets into tiny cracks in rocks. When the water freezes it expands, if this is repeated the crack grows and bits eventually break off.
How does rock type affect weathering?
It breaks rock down to smaller dimensions.
How rocks are mechanically weatherd?
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
What is the process that breaks down rocks chemically?
It's called chemical weathering. Think acid rain.
How does freezing water affect the weathering of rocks on a mountain's pinnacle?
Freezing water can affect the weathering of rocks on a mountain's pinnacle because the frozen water will expand within the cracks of the rocks of the mountain's pinnacle. The ice accumulations will also grow larger which will also affect the weathering of the rocks.
Which one of the following is a source of chemical weathering a The abrasion of running water b Water freezing in the cracks of exposed rocks?
b. water freezing in the cracks of exposed rocks
What type of weathering causes rocks to decay?
Wind, water, and freezing all cause rocks to erode or weather.
Is leaves decaying in the forest a mechanical weathering?
Is repeated freezing and thawing of water that cracks rocks
When water dissolves a rock and breaks it down into smaller rocks this is which type of weathering?
water erosion
Is dissolution a type of chemical weathering that breaks down rocks by absorbing water?
Yes
Is water freezing in cracks in rocks physical or chemical weathering?
Physical.
What is the type of mechanical weathering caused by water freezing and pushing openings in rocks?
ice wedging

Is water freezing in the cracks of exposed rocks a source chemical weathering?
No. Chemical weathering is only when acid rain etc. is involved. I suppose you could call this 'natural weathering' but I'm not sure that is the correct term because it is simply water freezing and expanding.
What is it called when water wind ice or heat breaks down rocks into smaller pieces?
It is called weathering.
