Mechanical Weathering

Front

Mechanical Weathering is the same as Physical Weathering

Back

True

Front

Mechanical Weathering breaks down rocks through _______.

Back

Force

Front

The grinding away of rock by rock particles carried by water, ice, wind, or gravity is called __________.

Back

abrasion

Front

Rock breaks off into leaves or sheets along joints which are parallel to the ground surface due to uplift and removal of surface material that covered the rock, this is called __________.

Back

exfoliation from uplifting

Front

Repeated daily heating and cooling of rock causes expansion; cooling causes contraction, different minerals expand and contract at different rates causing the rock to split, this is weathering by __________.

Back

thermal expansion

Front
