Asteroids, Plate Tectonics, And The Rise Of Granite On Earth

The video explains how giant asteroids impacted Earth, leading to the formation of plate tectonics. These tectonic movements resulted in the creation of granite, a rock with unique buoyancy properties. Granite's lower density compared to basalt allows it to rise to the surface, forming continents and mountain ranges. Over time, tectonic plates continue to move, accumulating more granite on Earth's surface.

What was the primary consequence of the giant asteroids impacting Earth?

• Formation of new oceans

• Creation of vast deserts

• Increase in Earth's temperature

• Fracturing of Earth's crust

What geological process was triggered by the asteroid impacts?

• Earthquakes

• Plate tectonics

• Volcanic eruptions

• Tsunamis

What characteristic of granite allows it to rise to the Earth's surface?

• Its magnetic properties

• Its color

• Its temperature

• Its density

How does granite compare to basalt in terms of density?

• Granite and basalt have the same density

• Granite is less dense than basalt

• Granite is denser than basalt

• Granite's density varies more than basalt's

What happens to granite when tectonic plates collide?

• It sinks into the mantle

• It forms new oceans

• It is pushed up to form mountains

• It melts into magma

What is the long-term effect of granite accumulation on Earth's surface?

• Expansion of oceanic crust

• Development of mountain ranges

• Formation of deserts

• Creation of new tectonic plates
