Valleys and canyons formation
Gravity pulls rainwater downhill forming
small streams.
These small streams join together
forming a bigger stream (river).
The water of the river flows fast across
the land and erodes a pathway through
the landscape forming a valley.
The fast flow of water erode a lot of
sediment and carry them away forming a
canyon.
Grand Canyon:
- The most famous canyon on Earth.
- It is located in USA.
- It is very large and steep canyon,
and it contains many layers of rocks.
