We call the movement of ocean water, ocean ________.

Boats

The hydrosphere represents all ______________ on planet Earth.

Water

100

What is a watershed?

An area where water drains to one water body (River, Ocean, Lake, etc.)

100

What does it mean for water to be potable?

It is safe for drinking

100

What is the hydrosphere?

All the water on Earth including oceans, freshwater sources and moisture in the air and clouds.

200

Which two factors affect water density in oceans?

Salinity ("saltiness") and temperature

200

Most of Earth's water is found in...

The Oceans

200

Water that does not infiltrate the ground, but flows directly into a river, lake or ocean.

Runnoff

200

What is the main reason excess nitrogen gets into the watershed?

Fertilizer runnoff

200

What is the Global Water Crisis?

Lack of clean, fresh water

300

What is upwelling?

When deep ocean currents rise to the surface, bringing up nutrients.   

300

Why is most of the water on Earth inaccessible to humans?

Because most water is either salty (oceans), frozen (ice caps) or underground (groundwater)

300

Ground that prevents water from percolating down into it is said to be...

Impermeable 

300
What are 4 indicators of water quality? (There are 7)

Temperature, pH, Dissolved Oxygen, Salinity, Turbidity, Nitrates/Phosphates, Bioindicators

300
Which of the following is non-point source pollution?

1. Chemicals released from a factory

2. Car Exhaust 

3. Fertilizer runoff from a farm

4. A large, leaking landfill

400
What affect does upwelling have on an ecosystem near the ocean's surface?

Upwelling brings lots of nutrients to the surface so the ecoysystem can support more life and therefore has higher biodiversity.

400

Put the following in order from most abundant to least: Groundwater/Surface Water/Frozen Water (Ice Caps and Glaciers)

1. Frozen water (77%), 2. Ground water (22%), 3. Surface Water (1%)

400

What are tributaries?

Smaller rivers or streams that flow into a larger one.

400
What role to bioindicators play in determining water quality? 

Bioindicators are living things who's absence or presence in water can tell us the overall quality of the water.

400
What process to organisms use to make their own food at the bottom of the ocean? 

Chemosynthesis 

500

How do ocean currents affect global climate?

Ocean currents act as a heat conveyor belt, transporting warm water to the poles (and warming the air) and cold water to the equator (and cooling the air).  

500

Only about __ % of ALL water on Earth is readily available for human use.

>0.05% of ALL water is readily available (fresh surface water)

500

Trace a molecule of water from the Atlantic Ocean to to the clouds, to Raleigh and back to the Atlantic using the appropriate terms. 

Water evaporates from the Atlantic, rises and condenses into clouds, falls as precipitation, hits the Earth's surface and infiltrates the ground or runs off back into tributaries that lead to the Neuse River which flows back down to the Atlantic Ocean.

500

What is eutrophication and how does it happen?

It is an excess of nutrients, usually due to fertilizer runoff, which causes an overgrowth of producers (mostly algae) and a reduction in animal life due to lack of oxygen.  

500
What affect does having a large area of impermeable surfaces have on the watershed?  

It creates more runoff which causes pollution to be delivered directly into the watershed, rather than being filtered by permeable surfaces.
