Question | Answer |
---|---|
delta | the flat triangular-shaped plain formed when a river empties into the ocean |
erosion | the gradual wearing away and REMOVING of rock material by forces such as moving water, wind, and moving ice |
sediments | sand,soil,and rock carried by water, wind, or ice |
river system | a river and the waterways such as brooks, streams, and rivers that drain into it |
weathering | the physical and chemical processes by which rock is BROKEN down into smaller pieces |
headland | a nature made piece of land that usually extends out into the water and usually slows down the flow of water that passes it. |

glacier | a huge mass of very slow-moving ice that forms over land |
moraine | materials such as large rocks that is carried by glaciers |
What human machine is a glacier often compared to? | bulldozer |
What part of a plant causes weathering of rocks? | roots |
What is the main force that makes glaciers move? | gravity |
What is the difference between weathering and erosion? | Weathering is breaking apart rocks into sediment. Erosion is carrying away the sediment through wind, water, or ice. |
What happens to the speed of water when a river reaches the mouth of the ocean? | The river loses energy and slows down. |
What most likely caused the grooves on Kelly's Island in Lake Erie? | Glacier |
Describe the term "frost heaves" and what causes them? | Frost heaves is when the ground is frozen and thrust upward. It is caused by freezing and thawing of water in the ground. |
What natural processes slowly wears away a stone sculpture? | Rain and wind |
