Objective:

YWBAT explain how the composition of rock affects the rate of weathering.

Drill:

Does the rate at which a rock undergoes chemical weathering increase or stay the same when the rock becomes more mechanically weathered? Why

HomeworkHomeworkStudy WOW

Answer

Mechanical weathering breaks down rock into smaller pieces, which

increases its surface area. This exposes more surface

area to the effects of chemical weathering.

Did you know…?A cemetery is a great place to observe the effects of differential weathering because several different kinds of rock are used to make headstones, and most headstones are dated.
