Question 4
4.

The United States is rich in natural resources, but lacks some strategic minerals. Name 2 reasons that we choose to import (buying materials from another country) rather than use what we already have?

Example: The US buys oil from the Middle East even though the US has lots of oil that we could use.

Question 18
18.

Read the information and answer the questions.
A coral reef is made up of organisms called corals. Corals are marine animals whose skeletons form the structure of the reef. The bright colors of coral reefs are caused by algae that live inside the skeletons of the corals and provide the corals with energy.
Coral reefs provide homes for about 25% of all marine species. The Coral Reef Ecosystem diagram shows some of the organisms found in a coral reef ecosystem.
When stressed, corals expel the algae, lose their bright colors, and become white. This is known as a coral bleaching event. If the stress lasts for only a short time, the corals can recover. But if the stress lasts for a long time, the corals can starve.
Question 19
19.

An increase in the temperature of seawater is one possible cause of coral bleaching. The Global Coral Bleaching Events graph shows the relationship between the change in seawater temperature and three global coral bleaching events.


The change in seawater temperature is correlated with the amount of carbon dioxide in the atmosphere. The Atmospheric Carbon Dioxide graph shows how the amount of carbon dioxide in he atmosphere has changed since 1960.

Question 20
20.

Question 21
21.

Describe what could happen to a healthy coral reef ecosystem if atmospheric carbon dioxide levels continue to increase.

Be sure to include:
- Describe one way a healthy coral reef ecosystem could change if atmospheric carbon dioxide levels continue to increase.
- Describe how that change to a coral reef ecosystem could affect other organisms in the coral reef ecosystem.

Question 22
22.

Question 23
23.

Coal, oil, natural gas and propane are fossil fuels, They are called fossil fuels because:
They are nonrenwable and will run out
They are formed from the buried remains of plants and tiny animals that lived hundred of millions of years ago
They are burned to release energy and they cause air pollution
They are mixed with fossils so they will burn better
Why is important to manage nonrenewable resources? Select all that apply.
They are in limited supply
To protect vulnerable ecosystems
Using them has no effect on the environment
Using them creates waste and pollution
They are cheap to produce
What is geothermal energy?
Geothermal energy is concerned with extracting more fuels from the earth to provide heat and energy.
Geothermal energy is heat from within the earth which can be used to heat buildings or generate electricity
Geothermal eEnergy is heat from the sun which can be stored and used as a efficient energy source.
As the cost for oil increases the demand will _________.
Increase
Decrease
Stay the same
What is a renewable resource?
A natural resource that is replenished at a rate less than its rate of consumption.
A natural resource that is replenished at a rate comparable to its rate of consumption.
A natural resource that we only obtain from another country.
Which of the following are considered non-renewable resources? Select all that apply.
Fossil Fuels
Fresh water
Wood
Minerals
Animals
Nuclear Power
When do "renewable" resources become "non-renewable"?
Pollution of the environment by humans.
When the resource can be recycled or reused.
When resources are used a higher level than they are being replaced.
When the temperatures become too high.
The state in which a fish population can survive indefinitely is called
loss of biodiversity
biodiversity
sustainability
renewable resource

A student claims that coral reef ecosystems are stable because they can recover after a bleaching event.

Which evidence should be collected to evaluate the student's claim?
