Water Erosion (Topic 9- LESSON #3-WATER EROSION)

What is Sheet Erosion?

• A type of erosion where runoff removes thin, uniform layers of soil from the surface of the land.

• A process where large rocks are broken down into smaller pieces by wind.

• The movement of soil and rock from one location to another by water, wind, or ice.

• A method of farming that prevents soil erosion by planting cover crops.

What is runoff?

• Water from rain or snowmelt that flows over the land's surface instead of soaking into the ground.

• Water that is absorbed by the soil during rainfall.

• Water that evaporates from the surface of lakes and rivers.

• Water that is stored in underground aquifers.

What is a Tributary?

• A large body of water that flows into the ocean.

• A smaller stream or river that flows into a larger main river, adding water to the main channel.

• A type of fish found in freshwater rivers.

• A geographical term for a mountain range.

What does the term Meander refer to?

• A straight path of a river

• A winding, loop-like curve or bend in the course of a river flowing across relatively flat land.

• A type of fish found in rivers

• A method of measuring land area

What is Karst Topography?

• A landscape formed from dissolving soluble rocks, characterized by sinkholes, caves, and underground drainage systems.

• A type of mountain range formed by tectonic activity.

• A flat landscape with no significant elevation changes.

• A coastal area characterized by cliffs and rocky shores.

Cave

• A large natural underground chamber formed by erosion of rock.

• A small enclosed space for storage.

• A type of geological formation found on the surface.

• A man-made structure for living.

What is an Oxbow Lake?

• A U-shaped body of water formed when a wide meander from a river is cut off by deposition.

• A type of lake formed by glacial activity.

• A lake that is formed by the accumulation of rainwater in a depression.

• A lake that is created by human intervention for irrigation purposes.

What is a Stalactite?

• A type of rock formation that rises from the floor of a cave.

• An icicle-shaped formation that hangs from the ceiling of a cave, formed by dripping mineral-rich water.

• A mineral deposit found in hot springs.

• A type of stalagmite that grows upwards.

Deposition

• The geological process in which sediments, soil, and rocks are added to a landform or land mass.

• The process of eroding landforms through wind and water.

• The movement of tectonic plates causing earthquakes.

• The formation of clouds and precipitation in the atmosphere.

What is a gorge?

• A narrow, deep valley with steep, rocky sides, typically formed by a fast-flowing river eroding the landscape over time.

• A large, flat area of land with few trees.

• A type of mountain that is very steep and rocky.

• A small stream that flows into a larger river.
