3. which of the following is not a gas giant planet? a. mercury b. jupiter c. saturn
4. which of the following is not a continent? a. north america b. china c. australia d. none of these
5. which of the following is caused by plate movement? a. mountains b. earthquakes c. oceans d. all of these

part iii: short answer (8 points)

1. why is the grid system important?
2. what is the difference between absolute location and relative location

Explanation:

1. The "Corn Belt" is a formal region as it is an area defined by a common characteristic (corn - production).
2. Saltwater makes up about 97% of the earth's water. This is a well - known fact in hydrology.
3. Gas giant planets are large planets mostly composed of hydrogen and helium. Mercury is a terrestrial planet, not a gas giant.
4. North America and Australia are continents, while China is a country in the continent of Asia.
5. Plate movement can cause the formation of mountains (e.g., Himalayas), earthquakes (due to the release of energy when plates shift), and the shaping of oceans (through processes like seafloor spreading).
6. The grid system is important because it allows for precise location identification on maps and globes, facilitating navigation, land - use planning, and geographical studies.
7. Absolute location is a fixed point on the Earth's surface, usually given by coordinates (latitude and longitude). Relative location describes a place in relation to other places.
