• radiation
• convection
• conduction

Multiple Choice

Thermal energy always moves from the area of lower temperature to areas of higher temperature.

• False
• Depends on the material
• Sometimes
• True

Multiple Choice

A group of friends gathers around a fire to stay warm. This is an example of

• Radiation

• cooking
• Conducation

• Convection

Multiple Choice

Why is the earth hotter at the equator?

• The sun's rays hit the equator more directly.
• The equator is closer to the sun.
• There are more greenhouse gases at the equator.
• The equator receives more sunlight throughout the year.

Multiple Choice

• albedo

• specific heat

• radiation

• Convection

Multiple Choice

• lower
• equal
• no
• higher

Multiple Choice

• true

• false

Multiple Choice

The Sun warming the soil is an example of____.

• nuclear fusion
• wind power
• solar radiation
• geothermal energy

Multiple Choice

The warm ground heating the air above it is an example of___

• evaporation
• radiation
• convection
• conduction

Multiple Choice

The measure of the reflectivity of a surface.

• reflection
• albedo

• absorbance
• refraction

Multiple Choice

A snow-covered mountain has a______ albedo than a dark-colored corn

field. Therefore, it will reflect ________solar energy than the field.

• Blank 1: more

  Blank 2: higher

• Blank 1: higher

  Blank 2: more

• Blank 1: water

  Blank 2: Sun

• Blank 1: less

  Blank 2: lowest

Multiple Choice

which will most likely absorb more solar energy, a field of light-colored crops or a forest of dark trees?

• The field, dark surfaces have a lower albedo and thus reflect less and absorb more solar energy.

• The field, light surfaces have a lower albedo and thus reflect less and absorb more solar energy.

• The forest, light surfaces have a lower albedo and thus reflect and absorb more solar energy.

• The forest, dark surfaces have a lower albedo and thus reflect less and absorb more solar energy.
