Energy Review

What happens to most of the sunlight that strikes a dark-colored area of Earth's Surface?

• It is reflected and scattered as potential energy

• It is reflected and diffused as ultraviolet radiation

• It is absorbed and reflected as light

• It is absorbed and reradiated as heat

When a heat source loses energy, that energy is

• reflected by a heat sink

• refracted by a heat sink

• scattered by a heat sink

• absorbed by a heat sink

Which color of the visible spectrum has the shortest wavelength?

• violet

• blue

• yellow

• red

Which material will heat up the quickest? (Reference Tables)

• Basalt

• Granite

• Water

• Copper

Which type of surface absorbs the greatest amount of electromagnetic energy from the Sun?

• Smooth, shiny and light colored

• Smooth, shiny and dark colored

• Rough, dull and light colored

• Rough, dull and dark colored

What is the primary method of heat transfer through solid rock during CONTACT metamorphism?

• Conduction

• Convection

• Advection

• Absorption

Changing the shingles on the roof of a house to a lighter color will most likely reduce the amount of solar energy that is

• Scattered

• Absorbed

• Reflected

• Refracted

Land surfaces of Earth heat more rapidly than water surfaces because

• More energy from the Sun falls on land than on water

• Land has a lower specific heat than water

• Sunlight penetrates to greater depths in land than in water

• Less of Earth's surface is covered by land than by water

How do clouds affect the temperature at the Earth's surface?

• Clouds block sunlight during the day and prevent heat from escaping at night

• Clouds block sunlight during the day and allow heat to escape at night

• Clouds allow the sunlight to reach the Earth during the day and prevent heat from escaping at night

• Clouds allow sunlight to reach the Earth during the day and allow heat to escape at night

What type of electromagnetic energy has the longest wavelength?

• Infrared radiation

• Radio wave radiation

• Ultraviolet radiation

• X-ray radiation
