Weather And Erosion
Project
By Taylor, Hannah, and Aaron
How was the Grand Canyon
formed?¿?
Activity 1
Erosion…
Ice- Water freezes into
cracks causing it to
expand.
Water- The Colorado
River broke away rocks
causing the canyon to
form.
Wind- Wind caused
abrasion which made
the canyon break down.
Volcanism
When volcanoes erupt, the lava
hardens and starts to form more
land.
Continental Drift
Continental Drift is when plates push
together forming the land to move
upward.
How did it happen?
Activity 2
These are the steps…
The river is
starting to
break away
the Canyon.
The river has
completely
broken down
the canyon.
When did all this happen?¿?
Activity 3
Time Line
The Earth was formed about 5 billion years ago.
1.25 billion years ago the Bass Formation was
formed.
About 1.2 billion years ago the first sedimentary
rock was laid down.
1.2 billion years ago the Hakatai Shale was
formed.
1.19 billion years ago the Dox Formation was
formed.
Between 1.25 and 1.1 billion years ago the
Cardenas Basalts were formed.
Between 1 billion and 825 million the Chuar
Group was formed.
Time Line
550 million years ago the
Tapeats Sandstone was
formed.
540 million years ago the
Bright Angel Shale was
formed.
530 million years ago the
Muav Limestone was
formed.
330 million years ago the
Redwall Limestone was
formed.
300 million years ago the
Supai Group was formed.
280 million years ago the
Hermit Shale was formed.
Time Line
270 million years ago the
Coconino Sandstone was
formed.
260 million years ago the
Toroweap Formation was
formed.
250 million years ago the
Kaibab Limestone was
formed.
The Colorado River caused
the layers to break away.
The Colorado Plateau help
uplift the layers causing
them to break down.
How the Grand Canyon was
formed by the Colorado River
over time?¿?
Activity 4
This is how it was formed…

Layers
Differences and Similarities of the
Grand Canyon and the Bryce
Canyon.
Activity 6
Similarities and Differences
Similarities
Differences
They both have the
same colors.
The Bryce Canyon
has more points.
They both have
layers.
The Grand Canyon
has less amount of
ledges.

Activity 7
Pictures..
This is an
example of
running water
erosion.
This is where water
and wind erosion
occurred.
This is running water
erosion that ran down
hill.
More Pictures…
This is where water
washed the dirt and
grass away, leaving just
the cement.
