Answer:
Scientists who study the Earth tell us the continents and ocean floors are always moving. This movement sometimes can be violent, causing death and destruction. Today, we examine what causes earthquakes and volcanic activity.
The first pictures of Earth taken from space showed a solid ball covered by brown and green landmasses and blue-green oceans. It appeared as if the Earth had always looked that way -- and always would.
Yet the surface of the Earth is not as solid or as permanent as had been thought. Scientists found that the surface of our planet is always in motion. Continents move about the Earth like huge ships at sea, floating on pieces of the Earth’s outer skin, or crust. New crust is created as melted rock pushes up from inside the planet. Old crust is destroyed as it moves toward the hot rock and melts.
The Earth seems to melt into the sea.
The Earth seems to melt into the sea.
In the 20th century, scientists began to understand that the Earth is a great, living and moving structure. Some experts say this understanding is one of the most important revolutions in scientific thought.
The knowledge of the Earth’s continual motion is based on the work of scientists who study the movement of the continents. This process is called “plate tectonics.” Earthquakes and volcanic activity are a result of that process.
Scientists say the surface of the Earth is cracked like a huge eggshell. They call these pieces “tectonic plates.” As many as 20 such plates cover the Earth. They sometimes hit each other, and sometimes move away from each other. Because some continents are above two plates, the continents move when the plates do.
