The correct answer is: c. Areas at low latitudes have the warmest water because they receive the most direct sunlight.
The warmest surface waters can be found in and around the Equator. The reason for that is that this parts of the world receive the most direct sunlight, with the sunlight falling at an angle of 90° or close to it. Because the sunlight is more concentrated, these areas are much warmer than the rest of the planet, having high temperatures throughout all of the year, where there isn't change of seasons, or its only dry and wet season (but the wet one is also warm). As everything else, the water too is warmer in these ares because of the more direct sunlight, and these are the ares where the warm ocean currents actually start.
Answer:
Pacific, Arctic and Atlantic

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:
1- Option (D)
2- FALSE
Explanation:
The seafloor spreading takes place because of the divergent plate motion. Alfred Wegener observed this motion of the seafloor and the continents but was not able to explain the main mechanism behind this until the new theory came into the picture. The divergent motion of seafloor and the motion of the continents were explained by the universally accepted theory known as the Plate tectonic theory. This theory was able to explain the mechanism behind this plate motion.
The study of the seafloor spreading provided some pieces of evidence that supported the continental drift theory. They gave a basic idea about how the oceanic plate gets subducted (consumed) at the convergent plate motion that undergoes partial melting at greater depth. As a result of which the magma rises up to the surface on the overriding plates.
The crust represents the outermost layer of the earth. They are of 2 types, namely the oceanic and the continental crust. These crusts when slide past one another in a transform plate boundary, it is neither created nor destroyed. It remains conserved.
Thus, the correct answers are given above and the second statement is false.
