To any student of geology and natural disasters, there is no way around it, the "Ring of Fire" is the most seismic active place on the planet. About 70% of the world's volcanoes and earthquakes take place here. Nonetheless, many dangerous volcanoes can be found elsewhere around the planet.
To determine the relative ages of rock units and create a timeline for geologic events in an area, geologists follow five key principles of relative dating.
Scientists say that Eurasia and the Americas might crash into each other in the Arctic and form a new continental land mass.
If you want to identify a mineral, you need to examine its properties. This is a guide to how scientists identify minerals by their physical properties.

The theory of plate tectonics grew from Alfred Wegener's theory of continental drift and incorporates modern data such as the magnetic record of the seafloor. The theory of plate tectonics helps to explain natural phenomena such as volcanic island arcs, large mountain belts, and seamount chains.
Diamonds are very important to our society because of the meanings we attach to them. But, where do diamonds come from? They form in four ways: deep eruptions, subduction, impact, and collisions in space.
