What are Earth's plates? Plate Tectonics: Plate tectonics refers to a theory that consists of the movement of the seven large Earth plates and the movement of the other smaller plates on Earth's lithosphere. The tectonic process began about 3 to 3.5 billion years ago. ...
A. Small pieces of the Earth's crust. B. Large pieces of the Earth's crust that move slowly. C. Pieces of the moon. D. Pieces of the sun. 相关知识点: 试题来源: 解析 B。解析:文章中提到“Tectonic plates are large pieces of the Earth's crust that move slowly over time.”,即构造...
The abiotic spheres—comprising the lithosphere, atmosphere, and hydrosphere—are made up of non-living components. Abiotic factors include elements such as minerals, gases, and water, all of which do not originate from living organisms. These spheres interact with each other and influence the Eart...

A new study says we may only have another 1.45 billion years to enjoy the dynamic action of Earth’s geologic engine.
There are eight major tectonic plates that move above the earth's mantle at rates up to 150 millimetres every year. In simple terms the process involves plates being dragged into the mantle at certain points and moving away from each other at others, in what has been dubbed 'the conveyor ...
Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other. Earthquakes are most common along fault lines, which are fractures that allow the plates to move. ...
Earthquakes are defined as a shaking of the earth's surface that occurs after a release of energy in the earth's crust (壳). Because the earth's crust is made up of numerous plates that are constantly moving slowly, shakings can occur and result in small earthquakes. Most earthquakes...
