Rivers Carve Canyons Over Time
Rivers Carve Canyons Over Time is a skill on Pengi from Sesson 2: Variables of Erosion (Speed & Time) in Amplify Science (California) Grade 4.
Key Concepts
The formation of a canyon is the result of the combined variables of speed and time. A river acts as a continuous saw, cutting through the Earth.
Through the slow, steady process of removing microscopic bits of rock and transporting them away, the river creates a deep gorge. This demonstrates how small, consistent changes over geologic time result in massive changes to the Earth's surface.
