Earth Systems Test Tci

Marcus is giving a presentation on Earth's energy flow at Science Night. His poster includes this model, which shows Earth's crust, mantle and core. Which sentence can he include as a caption that correctly describes how energy flows in this system?

• Energy flows from the cooler rock at Earth's crust toward Earth's core.

• Energy flows from the warmer rock at Earth's crust toward Earth core.

• Energy flows from the warmer rock at Earth's core towards Earth's crust.

• Energy flows from the cooler rock at the Earth's core towards Earth's crust.

• “Conduction” is the transfer of energy between objects that are touching.

• “Convection” is the transfer of energy caused by the circulation of matter due to differences in density.

• “Radiation” is the transfer of energy as light through space or transparent substances.

Which of the following is an example of conduction?

• If you hold a hot cup of tea, your hand will warm up.

• If you heat the air inside a hot air balloon, the balloon will rise.

• If you leave a chocolate bar in a hot car, the chocolate will melt.

• If you leave a glass of water on the counter, the water in the class will evaporate.

Brianna goes for a swim in the ocean. She swims away from shore, and as she begins treading the deeper water, she notices that the water on the surface is much warmer than the water touching her toes. What Earth process explains how the surface water was heated?

• gravity

• convection cells in the ocean

• radiation from the sun

• conduction of heat from Earth's crust
