learn about weathering, erosion, and
deposition. You will see examples of
weathering and erosion, including
famous places around the United
States! It’s going to be a great trip!

Weathering & Erosion
Weathering is the breakdown of materials in the Earth’s crust into
__________________. Erosion occurs when weathered rock is
__________________ away by gravity, water, wind, and
__________________. Weathering and erosion work together to
change the __________________. Physical weathering can happen
because of __________________, __________________, or
__________________. Acid rain and rust are examples of
__________________ weathering. Erosion moves sediment by
__________________, wind, and glaciers.

THE BREAK DOWN OF ROCKS
INTO SMALLER ROCKS
BECAUSE OF THE WEATHER
Weathering
16

Imagine you are holding a handful of sand.
Look closely. Each grain is actually a tiny
rock. It broke off a much larger rock.

The process of breaking down rock is called
weathering. Wind and water can hit rocks,
changing their shape or breaking off pieces.
Temperature changes can make rocks crack.
Ice can form, making cracks grow wider.
Rocks can also dissolve or change when
water or acids react with the minerals in a
rock.

Weathering
Weathering is the process of __________________ rocks down into
fragments, and then sediments. Weathering can change the
Earth’s __________________ over time. Mechanical weathering
breaks down rock without changing their __________________
composition. Examples of mechanical weathering include tree
__________________, expanding __________________, bolts of
__________________, and crystal formation. Chemical weathering
occurs when weathering changes the chemical composition of
something.

We learned that chemical
weathering changes the chemical
composition of an object.

Acids can mix with water molecules
and when it rains, acid rain falls to
the ground causing weathering.

Erosion
Erosion happens when water, wind, waves, or glaciers pick up stuff
like __________________ and __________________ from the
Earth’s surface and __________________ them around. Plant
__________________ hold sand and soil together, but when they
are not there, erosion goes __________________! Over millions of
years, water can cause deep __________________. Sand is made
by the process of __________________ rubbing together and
becoming smaller and smaller because of the motion of
__________________.
