There are three types of rock found on Earth. These are igneous, metamorphic and sedimentary. Each rock type is formed in a different way. For example, the rock malachite is mostly made of the ...

There are three types of rock; sedimentary, igneous and metamorphic. We call the study of rocks, and how they're formed, geology. Granite, an igneous rock, makes up most of the continents on Earth.

To find when plate tectonics began, experts led from Johns Hopkins University in Baltimore studied metamorphic rocks from across the globe that date back as far as 3 billion years ago.

Metamorphic rocks that are formed from igneous rocks won’t contain the combustible elements – the ones that burn – but metamorphic rocks made from sedimentary rocks might.

Abiotic organic synthesis during geological processes has long drawn scientific interest, as it is believed to have laid both ...

The most extreme rocks in America are ultrahigh temperature metamorphic rocks in Connecticut, which reached 1,800 degrees Fahrenheit (1,000 degrees Celsius.) ...

Discover Mount Shuksan's green top, all built from ancient oceanic greenschist. Greenschist is a special type of rock that gets its green tint from minerals compressed long ago deep under the ...
