FSSA Review: Heat Transfer

Which statement below is the best description of energy transfer by convection?

• from the sun to Earth

• from magma to the cooler rock touching the magma inside Earth

• by air moving from low elevations near Earth’s surface to higher elevations in the atmosphere

• between the water molecules on the ocean’s surface in contact with air molecules

Even on a very cool day, the plants inside this greenhouse stay warm if the Sun is shining. How does heat energy flow going into the greenhouse?

• circulation

• conduction

• convection

• radiation

The following diagram shows the process that warms the air above a lake. Which step shows conduction?

• Step 1

• Step 2

• Step 3

• Step 4

The following diagram shows energy transfer processes that happen above the ocean. Which step of the diagram involves convection?

• Step 1

• Step 2

• Step 3

• Step 4

Which type or types of heat transfer drive this motion of air?

• radiation and conduction

The movement of water through the oceans is one way that heat is transferred on Earth. By which process does water transfer heat from the equator to the poles?

• the Coriolis effect

• conduction

• radiation

• convection

Which of the following processes transfers the sun’s energy between particles as well as through empty space?

• conduction only

• radiation only

• convection only

• both conduction and convection

Different areas of Earth’s oceans receive different amounts of energy in the form of heat, resulting in ocean currents and weather patterns. What is the main source of this energy?

• kinetic energy from tides

• electromagnetic radiation from the sun

• kinetic energy from ocean currents

• energy transfer within Earth’s crust

The following diagram shows how some of the energy received from the sun is absorbed by Earth’s surface.

How is most of the solar energy transferred when it strikes Earth?

• nuclear energy to thermal energy

• nuclear energy to chemical energy

• electromagnetic radiation to thermal energy

• electromagnetic radiation to chemical energy

Which process is involved when solar energy warms the surface of Earth?

• conduction

• convection

• radiation
