The earth is made up of several layers(地层).The top layer of the earth is called the earth’s crust . The crust is divided into sections which are called plates. When two plates push against each other,or when two plates rub against each other,an earthquake happens. An earthquake causes...
Volcanoes and earthquakes are common features on the Earth's surface. Volcanoes occur when magma from deep within the Earth erupts onto the surface. Earthquakes are caused by the movement of tectonic plates. 1. The outermost layer of the Earth is called the ___. A. mantle B. core C. cru...
Scientists who study the earth's layers are called geologists. Since they cannot see the inside of the earth they use geographical clues to help them. These clues are gathered from activities such as volcanoes and earthquakes. From these clues geologists hypothesize (make an educated guess) what ...
