Which of the following is NOT a benefit from a catastrophic event?

• A flooded river deposits nutrients on the riverbank.

• A wildfire returns nutrients to the soil.

• A flood provides extra water to the environment.

What is erosion?

• The process by which weathered material is moved by wind, water, ice and gravity

• The process by which weathered material is deposited by wind, water, ice and gravity

• The changing of environmental conditions

What are the impacts of erosion on coastal areas?

• erosion attracts many tourists every year to coastal areas

• wildlife depends on the cycle of erosion

• erosion slowly eats away at beaches making them smaller

How can water break open rock?

• high pressure water is directed on a small spot on the rock and it erodes the rock over time

• water fills cracks in the rock and freezes, expands and pushes outward and breaks the rock down

• water cannot break open rock

The land area that supplies water to a river system is called a

• water table
• trailer
• house
• watershed

Tags

NGSS.MS-ESS2-4

When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.
• 
  clogging narrow streams and preventing water from flowing properly.
• raising the water level in nearby rivers to levels leading to flooding.
• causing rapid algal growth that decrease oxygen levels and choke aquatic life.
