The ground beneath us is moving, although it is at such a slow rate that it cannot be noticed by people. Over millions of years, however, this movement results in massive mountains and giant valleys. Answer and Explanation:1 Tectonic plates are made up of the material that forms our Earth...
Volcanoes are mountains that erupt lava and ash. They can be very dangerous. What causes volcanoes to erupt? A. Earthquakes. B. The movement of tectonic plates. C. The heat from the sun. D. Magic. 相关知识点: 试题来源: 解析 B。解析:火山喷发是由板块运动引起的。A 选项地震不是火山喷...
Even though the movement is slow, tectonic plates can have enormous impacts, creating impact phenomena, like mountain ranges, volcanoes, earthquakes, and tsunamis.Answer and Explanation: The seven tectonic plates are the Pacific plate, North American plate, South American plate, African plate, Antarct...
Plates sinking deeper into the mantle.C. Rocks from the base of tectonic plates.D. Movements of the magma of the mantle.9.What benefits more from the discovery of the new petit-spot volcano?A. Researching the movement of the upper mantle.B. Understanding the unknown asthenosphere.C. ...
Landforms are generally created by the movement of tectonic plates and through erosion. For instance, the collision between two tectonic plates can cause the Earth’s crust to fold and create huge mountains. It can also lead to the formations of volcanoes, which can both create and destroy new...

A fault is formed in the Earth's crust asa brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. ... If you whack a hand-sample-sized piece of rock with a hammer, the cracks and breakages yo...
The convection cycles of the mantle are the main cause of the movement of what part of the Earth? A. atmosphere B. core C. crust D. oceans What geological events occur because of convection currents in magma? How do convection currents cause tectonic plates to move?
were identified as part of the theory of plate tectonics, which was advanced and developed in the 1950s through the 1970s. Before plate tectonics was identified, there was no unified theory of geography, and scientists were unable to account for or describe the movement of tectonic plates....
