Mechanical Weathering
Mechanical weathering is the breakdown of rock into smaller pieces in physical ways. The different ways that mechanical weathering can happen is, ice, wind, water, gravity, plants, and animals.

Weathering from plants happens when plants force their way into rocks. First, the plant's roots find their way into a rock. Then, the roots force its way through it to get to water. Finally, the roots break through the rock and leaves it in pieces.

Weathering from ice happens when ice forms in a rock. First, water finds its way into cracks in the rock. Then, the water freezes and expands. Finally, the rock cracks and breaks from the expanded ice.

Weathering from wind happens when wind carries sand into a rock causing the rock to where away.This is a form of abrasion. This arch has been made from wind.

Weathering from water happens when water carries sediments or sand and rubs against rock causing it to wear away. This is a form of abrasion. The canyon has been made by the river at the bottom.

This picture shows an example of gravity weathering. Gravity weathers when gravity pulls pieces of rock down and causes them to break of there original place.

In this picture, there is a owl that burrowed. This is an example of weathering from animals. All animals that make a burrow are animals that weather. Other animals like,worms and ants also cause weathering.
