Answer:
Tidal friction caused by Earth's stretching from the Moon's gravity is gradually slowing down the rotation of Earth.
1. True
Explanation:
- The gravitational force of moon give rise to the tides in the sea and also it cause tidal friction. This tidal friction results in the stretching of the earth due to which the rotation of the earth is slowing down.
- The tides also affect the land and these tides causes the land to rise and fall by a much smaller amount than the oceans.
Answer:
The pressure at the top of Pikes Peak is much lower (only about 60% that at sea level).
Explanation:
Atmospheric pressure decreases with altitude. The higher a location is in the mountains, the lower the atmospheric pressure will be. Pressure continues to decrease until the boundary with outer space where there is no air pressure at all and the atmosphere officially ends. Mountain climbers that scale the highest peaks in the world must bring oxygen tanks because of the scarcity of air at the roof of the world.
