• The cold energy from your hand transferred to your friend's hand through conduction.

• The heat energy from your friend's hand transferred to your hand through conduction. 

• The cold energy from your hand transferred to your friend's hand through convection.

• The heat energy from your friend's hand transferred to your hand through convection.

• They would stop moving

• They would speed up

• There would be no effect

Describe the difference in how land and water heat and cool.

• Water cools and heats more quickly than land because water has a higher specific heat capacity.

• Land cools and heats more quickly than large bodies of water because as it has a lower specific heat capacity.

Which of the following is true about the heating of land and water?

• During the day, the Sun's energy heats up the land faster, which makes the air above it warmer.

• During the day, the Sun's energy heats up the water faster, which makes the air above it warmer.

• At night, the land cools off slower, making the air above it warmer.

• At night, the water cools off slower, making the air above it cooler.
