A-Day
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
Homework
Study 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.
