HESS unit 8 notes review

In what regions can coral reefs be found in

Coral reefs found in clean shallow water in tropical and sub-tropical climates

What do coral reefs contribute to the ecosystem

Coral reefs help provide shelter for marine organisms and give them a source of food

What are biologists main concern for coral reefs

There health and how there rapidly bleaching

What is coral bleaching

When coral begins or change colors to white which marks that they are beginning to die or already are

What are scientist trying to do to help the coral reefs

They study the changing conditions in the oceons and atmosphere

What is one of the reasons that coral bleaching is happening

Climate change heating up the water disrupting the temperature that corals need to survive

La Nina have unusually ______ ocean temertures

Cold

What are the conditions of La Nina

Dry and drought

What is another cause for coral bleaching

Another problem causing coral bleaching is the pollution and bad water quality that is getting worse because of the amount of pollution

Properties of water

Liquid at room temp with a boiling point of 100 degrees celsius and a freezing point of 0

“universal solvulent”

This means that is dissolves many substances such as salt and sugar

Surface tension

Meaning that the water molecules at the surface of the water are more attracted to each other then the air around them

Limestone

Lime stone is made of polar mineral called calcite and is found in shallow waters

What is the formula for finding percent concentrate

The amount of solute divided by the total amount of solution and to get the final answer multiply the result by 100

Why does water have such a high surface tension

The polar molecules stick to each other positive side to negative side

What category of ion are oxygen and hydrogen

Oxygen is slightly negative while hydrogen is slightly positive

What conditions cause waters level of salt to increase

Water that is found in areas where it cannot flow.
Water that evaporates at a high rate.
Water that is found in areas where it freezes often.

Plants release water into the atmosphere from the pores in their leaves through a process called ____?

Runoff

What is a water shed

A place where collected water from rain snow and other forms of precipitation are clumped together at one outlet such as a river or a lake

Generally speaking, where in Minnesota has radium been found in watersheds?

Southern Minnesota

Which possible water contamination is radioactive and is linked to fracturing Quartz rock underground as its source?

Radium
