Answer:
1)
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. ... The gravitational pull of the sun and moon on the earth also causes waves.
2) About 97 percent of Earth's water is in the ocean.
3) The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep.
4)Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
5)As fresh water evaporates, salty minerals dissolved in the water get left behind. Over time, this process made the Dead Sea much saltier than ocean water. The lake's saltiness means that larger organisms such as fish and frogs can't survive in the Dead Sea.
