As glaciers travel over land, glacial ice can erode the underlying bedrock.. This erosion can happen by:. Plucking. A. brasion. Plucking. This occurs when melt water at the base of the glacier freezes in cracks and fractures the underlying bedrock.. Chapter 7.1. At one time nearly 30% of the earth’s surface was covered in ice. . . This . period of time was referred to . as the . ice age. .. Today. , only . 10% of the earth’s surface is covered in ice. Landforms are the natural shapes or features of the land.. There are many different types of landforms found on Earth.. What are Landforms?. Mountain. A mountain is a place on Earth’s surface that is much higher than the land around it..

Introduction. Himalaya Region contains more glacial ice and perennial snow than any other region on earth outside the polar regions. Scenario #1. Flood water pounds against a canyon wall and wears it down.. Weathering. Scenario #2. Rain washing soil away from a hillside. Erosion. Scenario #3. Layers of sediment forming at the bottom of the ocean. Unit 5: Gradational Processes. Ms. . Thind. Glaciers. 10% of land is covered with glacial ice.. Store 75% of the world’s freshwater. . If all land ice melted, sea level would rise approx. 70m . Glaciers: importance?. Ch 15: p 277-281. Glaciers:. Enormous masses of moving ice created by the accumulation and compaction of snow..

Once . glacial ice exceeds a thickness of about 150 feet, the weight of the overlying ice causes . the . base of . the glacier . to become plastic and flow like a very viscous liquid. While the bottom ice responds as a plastic solid, the surface ice is very brittle. However, from the surface down to the top of the plastic portion of the glacier, the ice experiences a decrease in .
