Term | Definition |
sediment | The material moved by erosion |
deposition | the process by which sediment is laid down in a new location |
erosion | the process by which natural forces move weathered rock and soil from one place to another |
water | the major agent of the erosion that has shaped Earth’s surface |
river | formed when several streams flow together to form larger body of flowing water |
trubutary | a stream that flows into a larger stream |
runoff | the water that moves over the Earth’s surface after a rainfall |
meander | a looplike bend in the course of river |
caves | can be formed when groundwater and carbon dioxide create carbonic acid and erode limestone |
oxbow lake | a meander that has been cut off from the river. |
glacier | any large mass of moving ice and snow, which form u-shaped valleys |
valley glacier | a long, narrow glacier that forms when snow and ice build up high in mountain valleys |
continental glacier | covers much of a continent and is much larger and thicker than a valley glacier |
The times in the past when continental glaciers covered large parts of the earth’s surface were called | ice age |
The Great Lakes were created by | continental glaciers during the last ice age |
As a glacier flows over the land, it picks up rocks in a process called | plucking |
till | the sediments directly deposited by glaciers |
The till deposited at the edges of a glacier forms a ridge called | moraine |
Explain the type of erosion that creates caves, including how carbonic acid forms, and the type of rock that makes up caves | chemical weathering, carbon dioxide and rainwater, and limestone |
Explain how glaciers form and compare and contrast valley and continental glaciers | huge amount of snowfall and very cold, valley are slimmer and longer, continental are larger and wider. |
