What is all the water that runs off the surface of the land and washes into rivers, streams, and other waterways called?

Runoff

Storm Drain

Surface Water

Tributary

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.

The illustration provided shows a river and four cities on that river. When the water from the river was sampled at location X, it was determined to be polluted with various chemicals. What would be the most likely source for this pollution?

City 1 and City 2

City 2 and City 3

City 3 and City 4

City 1 and City 4

What is a watershed?

Land that collects and channels water froma small body of water to a larger body of water

the shape of the land determined by elevation

A natural stream of water of considerable volume

a river and all its tributaries

Review the graph showing marine fishing rates.If the fishing rate in Asia continues to grow, what will most likely happen as a result?

The fish population will continue to rise.

A wide range in ocean temperatures will be seen worldwide.

The U.S. human population will decline.

The overfishing will cause an imbalance in marine ecosystems.

What is one way humans are trying to positively impact the ocean?

Fishing

Drilling for oil and natural gas

Creating artificial reefs

Transporting goods in ocean vessels

What do we depend on the ocean for?

Food

Oxygen

Transportation

All of the above

Some areas of an ocean are known as dead zones. These zones form when excess organic material decomposes. This increased decomposition uses up the oxygen from the water.

Which human activity is most affected by the increasing number of dead zones in the ocean?

Offshore oil drilling, because water in dead zones is toxic

Commercial fishing, because fish cannot survive without oxygen

Commercial shipping, because dead zones change the course of ocean currents

Sand mining, because oxygen is not available to form the sands on ocean beaches

The process of taking fish out of the ocean before they have a chance to reproduce is called?

Invasive species

Over-fishing

Artificial reefs

Recycling

10.

Water that is found underground in the cracks and spaces in soil, sand and rock is called:

Groundwater

Percolation

Surface water

Aquifer
