Heathing of Earth

1. What does atmospheric transparency mean?

• how long the sun is above the horizon
• how high the sun is above the horizon
• cloud cover

What does duration of insolation mean?

• how long the sun is above the horizon

• how high the sun is above the horizon

• cloud cover

What does angle of insolation mean?

• how long the sun is above the horizon

• how high the sun is above the horizon

• cloud cover

A person in New York State worked outdoors in sunlight for several hours on a day in July. Which type of clothing should the person have worn to absorb the least electromagnetic radiation?

• dark colored with a rough surface

• light colored with a rough surface

• dark colored with a smooth surface

• light colored with a smooth surface

The diagram below shows a light source that has been heating two metal containers of air for 10 minutes. Both cups are made of the same material and are equal distances from the light source. Compared to the amount of energy reflected by the shiny cup during the 10 minutes of heating, the amount of energy reflected by the black cup is

• less

• greater

• the same

Which type of land surface would probably reflect the most incoming solar radiation?

• light colored and smooth

• dark colored and smooth

• light colored and rough

• dark colored and rough

Which of the following Earth surfaces usually reflects the most incoming solar radiation?

• snow cover

• dark soil

• green grass

• lake water

Liquid water can store more heat energy than an equal amount of any other naturally occurring substance because liquid water

• covers 71% of Earth’s surface

• has its greatest density at 4°C

• has the higher specific heat

• can be changed into a solid or a gas

On a clear summer day, the surface of land is usually warmer than the surface of a nearby body of water because the water

• receives less insolation

• reflects less insolation

• has a higher density

• has a higher specific heat

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
