Lesson 11.1: Earth's Internal Heat
Worksheet 1

Instructions: Write true if the given statement is correct, otherwise, write false.

1. True - Keeping Earth’s energy budget ensures that the average temperature on
Earth remains stable and that life continues to exist.

2. True - Some believe that Earth’s internal budget is completely balanced and that
same amount of heat is released and produced on the planet.

3. False - Earth's albedo is 0.3 which means 50% of the solar energy that reaches
the surface of Earth is reflected back to space by the clouds, atmosphere and
light-colored areas (deserts and areas covered with ice and snow).

4. False - The remaining 60% of the solar energy is absorbed by the atmosphere,
land, and oceans.

5. True - All solar energy absorbed by the atmosphere, air, land, and oceans must
be radiated back to space.

6. True - Unstable elements undergo radioactive decay to attain a more stable
form.

7. True - The process of radioactive decay produces heat as a byproduct.

8. False - The young Mars had more of these unstable elements producing a
greater amount of energy compared to today’s radioactive decay.

9. True - Collapsed clouds occur because accretion of more materials led to an
increase in the gravitational attraction causing the contraction of Earth into a
smaller volume which will then enable them to spin faster.

10. True - The compaction resulted in the conversion of gravitational energy into
heat energy.
