Answer:
Option (3)
Explanation:
Mid-oceanic ridges are the regions along which two distinct plates move away from one another. This type of plate boundary is known as the divergent plate boundary.
Whereas a rise occurs along a divergent plate boundary and is mostly associated with the region of hot-spots, where the magma is forced to rise up forming a gently steeper underwater highland area.
Both these features occur in a divergent plate boundary and plays an important role in pushing the continents apart. So we can conclude that the rises are mostly associated with the region of hot-spots, and ridges are formed due to the seafloor spreading at divergent plate boundaries.
Hence, the correct answer is option (3).
Answer:
Oceans = > 97 percent of Earth's water.
Glaciers = > 70% of Earth's freshwater
River = > Powered by gravity
Groundwater = > 100 times more water than all rivers and lakes
97% of the water on Earth is not drinkable as it is salt-water in oceans.
Of the 3% that is freshwater, Glaciers make up about 70% which means that we don't have access to a significant amount of freshwater either.
Of the available freshwater to us, groundwater comprises 98% which enables it to be 100 times more than all rivers and lakes.
Rivers are powered by gravity in that they flow from areas of higher elevation to areas of lower elevation as gravity pulls it downwards.
