The correct answer is - groundwater.
The freshwater is represented with only 3% of the total water reserves on the planet. Further more, most of the freshwater is actually frozen in the ice caps and glaciers on the poles and their close proximity, and that water accounts for around 87%. The rivers and the lakes do provide freshwater, but they only account for 1% of the total freshwater reserves, not to mention the fact that big portion of them are heavily polluted and can not be used for drinking at all.
The groundwater though, is much less polluted, is easy to extract and to use, and it accounts for around 12% of the total freshwater reserves, which makes the prime candidate for usage.
Answer:
(b) the night would be half as long
Explanation:
- As the earth, if rotated twice as fast than it does now and the sun stayed the same then the night would be as half as long as the rotation of the planet on its axis would be double to that of its and 12 hours of night would be as long as the speed of the axial rotation.
Most north locations on earth experience slightly over 12 hours of daylight, as well as the position of sunrise and sunset.
Pollution is the primary cause
Answer:
C.
Explanation:
Because the Earth is tilted on its axis not every part of the Earth gets the same amount of sunlight. This is the reason that we have seasons and why not every part of Earth has the same season at the same time or with the same intensity. People usually think this is because the earth moves away or closer to the sun but it is actually because of the tilt.
