Answer:
C. There is more usable freshwater below the earth's surface than there is above it.
Explanation:
A. Most of earth's freshwater is found in lakes and rivers.
Although lakes and river are one of the surface water that house the highest percentage of fresh water (about 0.3%) but most of the earths fresh water are not found in lakes and rivers but are found in ground water and ice caps and glaciers. This statement is definitely not true.
B. Almost half of the water in the U.S. is used for mining and industry.
According to USGS(US geological survey) most water usage in the US is for thermoelectric power and irrigation followed by public supply before the use for mining and industry comes in. The statement is wrong to say almost half of the water in the US is used for mining and industry.
C. There is more usable freshwater below the earth's surface than there is above it.
Fresh water in ground water constitute about 30.1 % fresh water found in the earth. In fact some of the fresh water found on surface water bodies like rivers migrated from ground water. Groundwater is the largest reservoir of usable fresh water. The statement is correct and it is true.
D. Water is called the "universal solvent" because it dissolves in most other liquids.
Water is regarded as a universal solvent because it dissolves more substances than any other liquid not because it dissolve in most other liquids.

Answer:
The Earth is constantly changing its position with the sun as the Earth tilts in relation to the sun. This creates the differences in the seasons and the annual warming and cooling cycles of the Earth’s Northern and Southern Hemispheres.
Explanation:
- When the North Pole tilts most toward the sun, the Northern Hemisphere experiences summer.
- Spring and Autumn) occur midway on the Earth’s journey from winter to summer and from summer to winter.
- On March 20 or 21 of each year, the Earth reaches the vernal equinox, which marks the arrival of Spring in the north and Autumn in the south. The autumnal equinox occurs on September 22-23 and marks the arrival of Fall in the north and Spring in the south.
- When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, and this has nothing to do with how close or far the Earth gets to or away from the Sun in its orbit. It’s all because the Earth is tilted on its axis.
