Though there are manydefinitions of the term “continent,”it is generally used to identify large distinct landmasses that make up our planet’s surface. The world’s land in total has over 57 million square miles of land according to the National Geographic Society. What we know as earth’...

into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed....
Likewise, the English, Scottish, and Irish love a full breakfast when they have the time. Their plates are heavy with bacon, sausages, a variety of egg dishes, grilled tomatoes, mushrooms, and inevitably toast with marmalade or jam. On the other hand, a small or “continental” breakfast ...
When two continental plates converge, neither can push the other beneath it. The result is a buckling effect at the point of collision. The earth is pushed up in both plates, but the most dramatic effect occurs in the middle. Over a long period of time, large mountains form, such as th...
What are the moving plates of the Earth's crust called? Continental Drift: Continental drift was a scientific theory which was proposed by a German scientist named Alfred Wegener. It proposed that the continental landmasses used to be joined together before they drifted away from each other. ...
(1’30’’) But the problem with this theory has to do with simple mechanics: a crane needs a wide and sturdy base to stand on or it will fall over. Well, as you get to the top of the pyramid, there’s really no place for a crane to stand. The stone blocks are too narrow to...
What Are Tectonic Plates: Even though our day to day life seems to occur on solid Earth, the Earth's crust is actually broken up into large sections called tectonic plates. These plates move based on convection currents of magma in the mantel. ...
There are now about 600 active volcanoes. Every year they add two or three cubic kilometers of rock to the continents. Imagine a similar number of volcanoes smoking away for me last 3,500 million years. That is enough rock to explain the continental crust. What comes out of volcanic ...
Continents are floating apart from each other, this is referred to as the continental drift. About sixty miles below the surface of the sea, there is a semimolten bed of rock over which plates, or slabs, carry continents and sea floors at a rate of several inches a year. As the plates...
