• convection

• radiation

• compression

Which of the following is the best example of increasing an objects potential energy?

• rolling a boing ball

• stretching a rubber band

• swinging a baseball bat

• dropping an apple

An object that has kinetic energy must be

• on the ground

• at rest

• in motion

• be held up high

Natural resources such as fossil fuels that cannot be replaced by natural processes as quickly as they are used are called ___.

• Renewable Resources

• Nonrenewable Resources

• Radioactive

Which of these is the best example of heat transfer by radiation?

• A snake is warmed by sunlight.

• Butter melts on warm bread.

• A ceiling fan cools a warm room.

In West Texas and Southern California, high winds drive turbines that generate electricity. One advantage that wind energy has over energy generated from solar cells is that wind energy —

• is plentiful everywhere

• can be generated at night

• produces cleaner energy

• is free of environmental hazards

When an object is at rest and not in motion it has

• thermal energy

• kinetic energy

• potential energy

• solar energy

The transfer of heat by the movement of AIR currents in Earth’s atmosphere is an example of

• conduction

• convection

• radiation

• fusion

True or False: The ability to do work is energy.

• True

• False

Which of the following is an example of solar energy being converted into chemical energy?

• Plants producing sugar during the day from sunlight

• Water evaporating and condensing in the water cycle

• The sun unevenly heating Earth’s surface

• Lava erupting from volcanoes for many days
