Chapter 6.1 Running Water

What powers the hydrologic cycle

• runoff

• gravity

• the Sun

• non-renewable resources

Factors that affect runoff are

• amount of rain

• rate of rain

• the phase of the moon

• vegetation

All rivers flow...

• down hill

• south except a few

• south in the Northern Hemisphere

• north in the Southern Hemisphere

Meanders are ____ on a river that is in its mature transportation stage.

• triangular deposition features

• curves

• straight raceways

• never

All the land that drains into a particular waterway is...

• an aquifer

• a watershed

• evapotranspiration

• a reservoir

Ways to help control non point source pollution include

• Apply pesticides or fertilizer when no heavy rain is forecast

• Compost organic waste

• Do not allow animal/pet waste to enter the waterway

• Dispose of all waste properly

Ocean -> Evaporation -> Condensation
Which of these would come next in the water cycle?

• Aeration
• Deposition
• Sedimentation
• Precipitation

Deposition by moving water in a river is most likely to occur as the

• water slows down
• water speeds up
• water becomes warmer
• riverbed becomes steeper

While gradient decreases between a stream's headwaters and mouth, discharge decreases.

• True

• False

which word matches the definition: the slope or steepness of a stream channel.

• Base Level

• Stream Flow

• Gradient

• Discharge
