It is possible to divide the surface of the globe into two hemispheres, one of which contains the larger part of its land and the other the larger part of its water surface. This bunching of the land has brought the people of the earth near together and has greatly facilitated their inter...

The top layer of the earth is called the earth’s crust. The earth’s crust is divided into seven sections. These sections are called plates. When two plates push against each other, or when two plates rub against each other, an earthquake will occur. An earthquake causes the ground ...
When the soil in the bottle has become entirely saturated with water, roughly compare the amount of air collected with the volume of the bottle containing the soil. What part of the soil’s volume is the air? The smaller the soil particles are, the more surface they present to water, the...

Nature is the international weekly journal of science: a magazine style journal that publishes full-length research papers in all disciplines of science, as well as News and Views, reviews, news, features, commentaries, web focuses and more, covering all branches of science and how science ...
he Earth's structure is made up of several layers. The crust is the outermost layer on which we live. Right beneath 1 the mantle (地幔), a warm, semi-liquid layer of rock. This is 2 by a thin shell of liquid iron that forms the outer core. 3 , there is a solid inner core, ...
The earth is divided into three main layers—a hard outer crust, a soft middle layer and a center core. The outer crust is broken into massive, irregular pieces called "plates." These plates move very slowly, driven by energy forces deep within the earth. Earthquakes occur when these moving...
then it must be contracting. As the crust is already cool it has ceased to contract and thus the interior shrinks away from it and it must fold up in order still to rest upon the shrinking interior. The cooling of the earth is so slow that the folding under ordinary conditions disturbs ...
The crust is composed of many different types of rocks that fall into three main categories:igneous,metamorphicandsedimentary. However, most of those rocks originated as either granite or basalt. The mantle ben
