Weathering | is the breaking up of the rocks on Earth's Surface into smaller pieces of sand or rocks. |
Water seeps into small | cracks in the rock. |
When the temperature falls below freezing, | water expands as it becomes ice. |
Freezing and thawing make the cracks | bigger until some of the rock breaks away. |
Rocks carried down a swiftly moving river are | weathered as they bump against each other. |
Particles carried by wind also | smooth and polish the rock as they strike its surface. |
Small pieces of rock produced by | weathering become soil of sand. |
Erosion is the | process of moving weathered bits of rock from one place to another. |
Glaciers, | thick layers of ice cause erosion. |
The snow turns in to ice | and gravity pulls it slowly down a hill. |
The glacier | erodes away the surface beneath it. |
Boulders and rocks carried in the ice, | scrape the rock beneath the glacier carving valleys into mountainsides. |
Water erosion | moves the MOST rock on Earth's Surface. |
Rain carries the soil away as it washes over the land, | leaving gullies, valleys,and canyons. |
Wind is not strong enough to | carry large rocks away. |
The downward pull of gravity | affects all erosion process. |
Arches, valleys, canyons and buttes are | continual changing g due to the effect of weathering and erosion. |
This change takes | millions of years. |
Uplift occurs | when part of Earth's Surface rises above the surrounding land. |
This occurs when great forces of | heat and pressure deep within Earth move solid rock. |
Uplift formed the Colorado Plateau, | creating nearly all the spectacular variety of canyon country in Utah. |
Deposition | is the dropping of sand and rock carried by wind or water. |
The sand of rocks | now live in a different place. |
