Sci 6 Surface Water Section 1 notes 1-20

What that flows across Earth's surface instead of soaking in or evaporating is called?

• Groundwater

• Runoff

• Precipitation

• Condensation

How does SLOPE effect the amount of water erosion?

• A GENTLE slope gives the water MORE energy to do MORE erosion.

• A STEEP slope gives the water MORE energy to do MORE erosion.

Scars left on a slope where small streams carried away plants & soil during heavy rains is called:

• Gully Erosion

• Stream Erosion

• Sheet Erosion

• Rill Erosion

Water continues to flow along a low place, picking up sediment from the bottom and sides of the channel to form a DEEPER, WIDER CHANNEL during:

• Sheet Erosion

• Stream Erosion

• Rill Erosion

• Evaporation

The LAND AREA where stream get their water is called:

• Sheet Erosion.

• a Drainage Basin.

• a Floodplain.

• the Water Cycle.

The 3 Different Stages of Stream Development depend on:

• the AGE of the STREAM.

• the AGE of the PERSON who NAMED the Stream.

• the SLOPE of the Ground.

Which type of stream moves quickly, has steep valleys, rapids, and waterfalls?

• Young Stream

• Mature Stream

• Old Stream

Which type of Stream flows slowly and travels through a BROAD floodplain?

• Young Stream

• Mature Stream

• Old Stream

What are the curves that form because the speed of the water changes throughout the width of a stream channel called?

• Floodplain

• Drainage Basin

• Waterfall

• Meander

What is the Broad, Flat VALLEY floor carved by a meandering stream called?

• Drainage Basin

• Plateau

• Gully Erosion

• Floodplain
