We depend on 75 percent of the freshwater supply of the world
Answer:
Sunlight cannot penetrate into the deeper oceanic zone
Explanation:
The oceans are extensively large bodies of water and are comprised of varying depth from place to place. The equatorial and the tropical region receives the maximum amount of sunlight as a result of which the ocean surface temperature rises significantly. So, the surface water up to a depth of about 200 to 300 meters below the sea level remains warm, as sunlight can easily penetrate in this zone.
But, at a depth more than about 300 meters to a depth of 1000 meters, this sunlight cannot penetrate and due to this reason the water in this zone remains cold enough. Thus, the temperature of the ocean water decreases with the increasing depth.
Which one do you need help with?
Answer:
The main difference between them is that; Wegener's Continental Drift postulates that earth was made up of a single continent, while the theory of Plate Tectonics states that earth's surface is broken into numbers of shifting plates or slabs.
Explanation:
Wegener's Continental Drift was a theory set forth by <em>Alfred Wegener in 1912. </em>He explained how continents shift positions on earth's surface. This movement happened over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
While on the other hand, the Theory of Plate Tectonics is the theory that the outer shell of earth is divided into several plates that glide over the mantle(the rocky inner layer above the core). The plates act like a hard and rigid shell compared to Earth's mantle.
