• Ice freezing and breaking rock
• Topsoil blowing away
• Water wearing down sandstone

Liquid water can seep into cracks and crevices in rock. When the temperature drops low enough, the water freezes and expands, and can eventually split the rock. The ice acting as a wedge in the rock demonstrates the process of __________________.

Where the river makes a sharp bend to the right, there is a beautiful sandbar. We sometimes can find fossil turtle shells partially buried in this sand. The formation of the sandbar demonstrates the process of __________________.

Years ago, the rancher dug out an area to build a pond for his cattle, but over time, the pond filled with sediment, so now, there is very little room for the water. The presence of the sediment in the pond demonstrates the process of ______________.
