Answers
1. Which method of heat transfer is used to transfer heat from the sun to the deepest layers of soil?
Radiation to surface soil
Conduction to deep soil (soil to soil is solid)
2. Which method of heat transfer is used to transfer heat from the sun to the deep water in oceans and lakes?
Radiation to surface water
Convection to deep water (liquid)
3. Recopy the diagram on page 17 (figure 1.7) and label it with the following words:
(a) Radiation
(b) Conduction
(c) Convection
(d) Soil
(e) Convection Current
(f) Lake
4. What happens to hot air? Why?
It rises.
It is less dense.
5. List the three ways that energy may be transferred. Give an example of each, other than the beach
example.
Radiation – from a heater to your hand
Conduction – from a stove top to a pot
Convection – the boiling water bubbles reach the surface
6. Explain how Earth maintains its relatively constant temperature.
It radiates as much energy back into space as it receives from the sun.
