Introduction

Introduction

1.During winter, water seeps into rock. As it freezes, it creates cracks in the rock.

2.Ice forces the cracks to become larger and larger, eroding bits of stone in the process.

3.During rainfall, water rushes down the cracks, eroding more bits of stone.

4.As more rocks crumble, the canyon forms.

The Beginnings

The Beginnings

Canyons usually begin because of water erosion. Rivers carve through rock and soil creating a chasm, which allows ice to fall in and freeze, making the crack larger.

Erosion continues when more water seeps into the previously formed cavern. It freezes, enlarging the crack. It then thaws. repeat until the rock splits.
