Continental crust is composed of granitic rocks made up of relatively lightweight minerals such as quartz and feldspar. In contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.

WebThere are a total of 15 tectonic plates and 42 secondary. They constitute the most solid part of the planet. Are covered by oceans known as oceanic plates. Through them, earthquakes, volcanism and orogenesis are produced. The earth is the only planet that has tectonic activity by means of plates. Oceanic plates are lighter than continental WebII. (5%) Describe the 3 fundamental types of plate tectonic boundaries and the motion of the plates at the boundary. Give a geographic example of each type. 1. Divergent: where adjacent tectonic plates both move directly away from the plate boundary, therefore, over time the two plates must diverge. A present-day geographic example of this type

WebThe lithosphere is the outermost layer of the Earth and is composed of both the crust and the uppermost part of the mantle. It is also where the tectonic plates are located. Which type of tectonic plate boundary occurs when two plates move away from each other? A divergent boundary occurs when two plates move away from each other. WebAnd when we talk about plate tectonics the plates are actually lithospheric plates. It's actually the lithosphere that's moving on top of the lower layers of the mantle. So the …
