The earth is formed of layers. The surface of the earth, about 200 kilometers thick, is made of large pieces. When they move against each other, an earthquake happens. A large movement causes a violent earthquake, but a small movement causes a mild one. Earthquakes last only a few ...

1The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of (硅酸盐) that are semi-molten at depth, and the thin, solid-surface crust. There are two kinds of crust, a lower and denser oceanic crust and an upper, lighter continental crust found over only ...
You can learn what supplies you'll need and discover useful resources for studying each of the Earth's layers. Building a Model This project allows students to use their creativity to build a model of the Earth's internal structure and can be completed using a variety of materials. ...
The Earth’s layers (strata) shown to scale. Credit: pubs.usgs.gov The thinner parts are the oceanic crust, which underlies the ocean basins at a depth of 5-10 km (~3-6 miles), while the thicker crust is the continental crust. Whereas the oceanic crust is composed of dense material ...
