This type of weathering in which rock is physically broken into smaller pieces.
Chemical weathering
Erosion
Mechanical weathering

The grinding/scratching away of rock by other rock particles carried in water, ice, or wind
Frost wedging
Exfoliation
Oxidation
Abrasion
A student wanted to demonstrate weathering and erosion. The student put the same number/size of rocks into 2 tin cans, then added a small amount of water to both cans. Can A was shaken at a constant rate for 15 minutes, and can B was shaken for 60 minutes. The student then drained out all of the water and placed the rocks on the desk to observe. What is the best prediction of how how the rocks will look after this experiment?
The rocks in can B will become larger and rounder than can A
The rocks in can B will become smaller and rounder than can A
The rocks in can A will become smaller and rounder than can B
The rocks in can A will become Larger and rounder than can B
A student prepares a model by filling a plastic bottle with water, capping it tightly, and placing it in the freezer for 24 hours. After 24 hours, there are large cracks on the bottle's sides. The student's model most likely represents which of the following types of weathering:
Acid rain
Oxidation
Frost wedging
Abrasion
Tectonic plate motion affects the rock cycle, which term do we use for crust moving to higher elevations? (Rising)
A glacier deposited large amounts of sediment after it had melted. Is this an example of a constructive or destructive force?
constructive
destructive
Contact metamorphism occurs when...
biological remains are compacted
