When tectonic plates shift and release energy that causes the ground to shake.

When the earth shakes really hard.

When the earth spins too fast.

When the tectonic plates accidentally bump into each other.

Rain can wash away the soil and deposit it to form mountains.

After several years of heavy rain a river formed and the river eroded the soil forming canyons.

Rainwater formed small ditches that grew. As the ditches grew, erosion increased which created the canyons.
