Hey there! I'm happy to help!
Imagine a line going straight from the North Pole straight down to the center of the Earth. Then, imagine another line from the Equator going through the Earth and meeting the vertical line. This makes a right angle. A right angle is 90 degrees, so this means that there are 90 degrees of latitude. All of the calculations for degrees of latitude are based around this!
For example, if you move the line from the top of the North Pole to Mexico (a (Tropic of Cancer), the angle inside the Earth is 23.5 degrees. You can move this top line around to get different angles with the equator, and that's where they all come from!
Have a wonderful day and keep on learning! :D
Surface of the Earth: Most of the Earth's surface (70%) is covered with water, and the remaining 30% is taken up by the seven continental landmasses. However, underneath the water that fills the oceans, and the dirt and plants that cover the continents, the Earth's surface layer is made of rock.
Answer:
Continental shelf
Explanation:
The subdustion zones between the oceanic tectonic plates and continental tectonic plates go in both ways when it comes to the lithosphere. They are both destructive and constructive. With the subduction zone occurring, the crust from the oceanic plate gets into the mantle, gets melted, and thus destroyed. On the other hand, this type of boundary enables the magma from the mantle to penetrate through the crust and reach the surface. As the magma reaches the surface, it starts to create volcanoes, be it in the form of island arcs or continental arcs. The volcanoes then release lot of lava from them on the surface, and this lava cools off and creates new layers of rock. The uplifting volcanoes, as well as the push of the plate that subducts, results in creating a shellow and relatively flat part of the ocean which is alongside the coastline. This shallow and flat part of the ocean is known as continental shelf. The continental shelf is the part of the ocean that has the warmest water, the light penetrates through all of its waters, and it is the most abundant in life. It depth is relatively small.
