Description of Conditions That Cause Physical Weathering
Occurs when the outer layers of rock slowly peel away over time
as a result of changes in pressure. An example of this is when
roads are cut through mountains.
The breaking down and wearing away of rocks over time as
a result of the flowing water in streams, strong winds, moving
glaciers, or gravity.
Burrowing animals break apart and mix rocks and soil. Their
actions also improve soil drainage and allow oxygen to get
underground which increases the rate of weathering.
Causes cracks in rocks to expand as liquid water seeps in
during the day when the temperatures are above freezing, and
then the water freezes at night and pushes the rock apart.
Roots start as tiny strands of plant matter that can grow inside of
the small cracks in rocks. As the roots grow bigger, they push the
rocks apart.

A. Ice-Wedging
B. Abrasion

Rock Classifications and Characteristics
An organic sedimentary rock that forms from the remains of dead
plants and animals.
When Halite “comes out of solution,” this type of chemical
sedimentary rock forms.
When clay grains accumulate, they form this type of clastic
sedimentary rock.
This fine-grained, extrusive igneous rock is dark-colored. It is
composed of iron and magnesium.
When the clastic sedimentary rock called Shale is subjected to
the heat and pressure of metamorphism, this rock forms.
Quartz Sandstone is a clastic sedimentary rock. When it is
undergoes metamorphism, this rock forms.
This coarse-grained, intrusive igneous rock is light-colored
containing feldspar, quartz. It composes continental crust.
This clastic sedimentary rock is composed of mostly rounded
pebbles along with sediments of many different sizes.
When sediment grains between .06 – 2.0 mm are compacted
and cemented together, this clastic sedimentary rock forms.
This type of metamorphic rock forms when the sedimentary rock
limestone is subjected to extreme heat and pressure.
Rock Type
A. Sandstone
B. Slate
C. Marble
D. Basalt
E. Conglomerate
F. Rock Salt
G. Shale
H. Quartzite
I. Coal
