Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust
The mantle is the thickest layer of Earth, making up about 84% of the planet’s volume. It extends from the bottom of the crust to a depth of about 2,900 km. It is composed of silicate rocks rich in iron and magnesium. The mantle is semi-fluid and contains convection currents that ...
Kepler’s second law of planetary motion, in astronomy and classical physics, one of three laws describing the motions of the planets in the solar system and which states that a radius vector joining any planet to the Sun sweeps out equal areas in equal

The Water Cycle consists of a number of steps. Learn how water moves above and below the surface of the earth with a neat labelled diagram of Water Cycle
A volcano is a place on the Earth's surface (or any other planet's or moon's surface) where molten rock, gases and pyroclastic debris erupt through the earth's crust. Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some ...
A landform diagram provides a window into the past, present, and future of our shared planet. Using the key ideas of uniformitarianism, the law of original horizontally, the law of superposition, crosscutting relations, and unconformities, learn to deduce the progression of a landscape,...
While some scientists are hard at work investigating phenomena beyond Earth, others are still making new discoveries on our planet. Among the discoveries that keep piling up are theidentification of various semiprecious stonesand minerals. In fact, there are more than 5,000 different types of mine...
Phase diagram, graph showing the limiting conditions for solid, liquid, and gaseous phases of a single substance or of a mixture of substances while undergoing changes in pressure and temperature or in some other combination of variables, such as solubil
