Energy in Earth Science

Which transfer of energy occurs mainly through the process of convection?

• Electromagnetic energy transferred from the Sun to the moon
• Solar Energy transferred through space to the Earth's surface
• heated air in the lower atmosphere transferred upward by density differences
• heat from radioactive decay transferred by molecular collisions to surrounding mantle rock

 As heat energy is added to an open container of boiling water, the temperature of the boiling water willQuestion*

• decrease
• increase
• stay the same

An object that is a good radiator of electromagnetic waves is also a good

•  insulator from heat
• reflector of heat
• absorber of electromagnetic energy
• refractor of electromagnetic energy

During which phase change of water is the most energy released into the environment?

• water freezing
• ice melting
• water evaporating
• water vapor condensing

Pieces of lead, copper, iron, and granite, each having a mass of 1 kilogram and a temperature of 100ºC, were removed from a container of boiling water and allowed to cool under identical conditions. Which piece most likely cooled to room temperature first?
