11th Grade Science E Block Review

What creates Energy?

What are nonrenewable resources?

NONRENEWABLE RESOURCES

A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

COAL, PETROLEUM, AND GAS

Coal, petroleum, and natural gas are considered nonrenewable

because they can not be replenished in a short period of

time. These are called fossil fuels.

HOW IS COAL MADE ???

HOW ARE OIL AND GAS MADE ???

NUCLEAR ENERGYNuclear fission

uses uranium to create energy.

Nuclear energy is a nonrenewable

resource because once the uranium

is used, it is gone!

Nuclear Power Plant

What is a renewable resource?

Let us think....

If nonrenewable resources are

resources that cannot be re-made at a scale

comparable to its consumption, then

renewable resources would be………?

RENEWABLE RESOURCESA renewable resource is a natural resource that can be re-made or re-grown at a scale comparable to its consumption.Types:

Solar, Geothermal, Wind, Biomass, Hydroelectric

SOLAR

Energy from the sun.

Why is energy from the sun renewable?

Comparing Solar energyActive solar

Energy

• Uses a device to concentrate solar energy

Passive Solar Energy

• Does not require a mechanism to utilize solar heat

• Windows facing the South

GEOTHERMAL

Energy from Earth’s heat.

Why is energy from the heat of the Earth

renewable?

Geothermal Energy Production

WIND Energy from the wind.

Why is energy from

the wind renewable?

BIOMASSEnergy from

burning organic or

living matter.

Why is energy from biomass renewable?

WATER or HYDROELECTRIC

Energy from the flow of

water.

Why is energy of flowing

water renewable?

Test-taking strategies• Carefully read each Question and Answer.• Look closely at the visual information

– Graphs, pictures, tables• Use your knowledge to eliminate answer

choices.• Answer every question.• Mark those you wish to review again• Use your best handwriting• Answer all parts of the open-ended questions

Sample Test Questions

1. Which system uses a nonrenewable

resource to generate electricity?

A wind turbines using air movement

B solar panels using the Sun’s radiation

C geothermal power plants using steam

D nuclear power plants usingradioactive elements

2. Which statement correctly describes

an energy source and its effect on the

environment?

A Fossil fuel, which comes from a continuously renewable resource, generates greenhouse gases.

B Solar power, which comes from a continuously renewable resource, generates greenhouse gases.

C Nuclear energy, which comes from a nonrenewable resource, generates dangerous waste.

D Hydroelectric power, which comes from a nonrenewable resource, generates dangerous waste.

Short Opened-Ended Question (2 pts)3. The Arctic National Wildlife Refuge in Alaska is

over 19 million acres of land. Its unique habitat supports at least 45 species of land and marine animals, 36 species of fish, and 180 species of birds. Some people want to drill for oil in parts of the refuge. Scientists estimate that the total amount of recoverable oil in the refuge is between 5 and 16 billion barrels.

Part A: Describe an environmental problem that could be caused by drilling for oil in Alaska.

Part B: Describe a regional benefit of drilling for oil in Alaska.

Scoring GuideScore In this item, the student—

2-demonstrates a thorough understanding of the impact that drilling for oil in Alaska will have on the environment by describing an environmental problem that could be caused by drilling, and describing a regional benefit drilling in Alaska could provide to the region. The response is clear, complete, and correct.

1-demonstrates a partial understanding of the impact that drilling for oil in Alaska will have on the environment by describing an environmental problem that could be caused by drilling, or describing a regional benefit drilling in Alaska could provide to the region. The response may contain some work that is incomplete or unclear.

0 provides insufficient evidence to demonstrate any understanding of the content being tested.
