Answer:
It comes from deep, protected underground aquifers.
Explanation:
- The groundwater is a water present beneath the surface deep within the soil pores and fractured rocks. An unconsolidated deposit named as aquifer contains unstable but drinking water, as this water is recharged from the surface.
- It's often regarded as cheap, convenient and pollution-free as most of the industrial and agricultural wastewaters does not reach such great depths.
- Thus making up 20% of the freshwater in the world. And hence regarded as a long term natural water cycle. The groundwater moves around 16 miles per day thus are filtered.
The answer is true because that helps them pinpoint locations across the globe.
I got you. a, 1, software, x. haha hope this helped
Answer
The region of the earth that John Tuzo Wilson believed was broken into plates was the “Hotspots” i.e. The Hawaiian Island.
Explanation
The two major contributions of John Tuzo Wilson towards the solidification of the theory of plate tectonics were the introduction of hotspots and the recognition of transform boundaries. The earlier scientific arguments concerning plate tectonic theory was the existence of volcanically active areas present in the middle of plates. The lack of explanation was addressed by John Tuzo who used the Hawaiian island as an example of an island chain that is volcanically active which was a sticking point for some opponents of the plate tectonic theory. He explained that the origins of volcanic rocks in such places are plumes rising from hotspots within stable core of mantle convection cell.
