Earth Science Lesson 1.1

Front

How does energy move through the crust?

Back

Conduction is the process by which heat energy is transferred through direct contact between materials.

Front

What is an example of heat transfer when the sun warms your skin?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Front

What are the three types of thermal energy transfer?

Back

Conduction, Convection, and Radiation are the three types of thermal energy transfer.

Front

What has the highest albedo?

Back

Glacial ice has the highest albedo, meaning it reflects most of the sunlight that hits it.

Front

Where do cold ocean currents generally originate from?

Back

Cold ocean currents generally come from either pole, the North Pole or the South Pole.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through a material without the movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Explain radiation in terms of energy transfer.

Back

Radiation is the transfer of energy through space by electromagnetic waves, which can occur in a vacuum.

Front

What is albedo?

Back

Albedo is a measure of how much light that hits a surface is reflected without being absorbed.

Front

How does the albedo of glacial ice compare to that of oceans?

Back

Glacial ice has a higher albedo than oceans, meaning it reflects more sunlight.
