Solar Energy on Earth Review

This is the transfer of thermal energy by electromagnetic waves and how energy from the sun reaches Earth.

• Conduction

• Radiation

• Convection

Why are latitudes near the poles cold? (p.152-153)

• The poles receive a lot of direct sunlight and have more energy per unit of surface area.

• Sunlight is spread over a larger area near the poles resulting in less energy per unit of surface area.

Surfaces on Earth with high albedo

• Reflect more sunlight

• Absorb more sunlight

Why is Earth warmer at the equator and colder at the poles? (p.152-153)

• Earth's spherical shape causes the equator to receive direct sunlight all year resulting in more sunlight per unit of surface area.

• Earth's spherical shape causes the equator to get less direct sunlight all year resulting in less sunlight per unit of surface area.

According to your lab data on p.155 and text on p.156, what is true about land vs water?

• Land absorbs and releases thermal energy relatively quickly compared to water.

• Water absorbs and releases thermal energy relatively quickly compared to water.

How do surfaces on Earth affect the atmosphere 🌏? Which statement best describes what happens during the day and night to the atmosphere over the land and water?

• The air above the land will absorb thermal energy quicker and will also release thermal energy quicker at night.

• The air above the water will absorb thermal energy quicker and also release thermal energy quicker at night.

How did the silver and black cans transfer energy to the water?

• By the process of conduction

• By the process of radiation

Snow and Ice have a

• high albedo and reflect light

• low albedo and absorb light

Dark surfaces on Earth have a..

• high albedo and reflect light energy

• low albedo and absorb light energy

What does most sunlight do when it reaches earth?

• Gets absorbed by the surface

• Gets reflected by the surface

• Gets absorbed by the air

• Gets reflected by the air
