Geology

Where are the world's supervolcanoes? The Western United States, Italy, New Zealand, and Asia all contain volcanoes capable of catastrophic eruptions.

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.

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.

Time is money. Even an amateur prospector can improve the odds of making some coin by classifying in conjunction with sluicing. Saving your back by shoveling once can cut the medical bills! A high banker can do all this and more. Fundamentals, design, physics, and mechanical descriptions follow.

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.

Land subsidence caused by groundwater withdrawal poses a significant threat to governments, businesses, and the general public.

These phrases are known by most us: Flushing it down the toilet, a diamond in the rough, a pearl in the wild. They all refer to finding value where none is expected. As it turns out, human waste contains precious metals and gems washed down the drain unconsciously during our hurried lives.

This article looks at the processes by which rocks melt and the different ways they cool and solidify to form igneous rocks.

Unique and rare Septarian brown stones among other types are found along a narrow stretch of Lake Michigan shorelines. Find out the one other place in the world they can be found.

The Bolshaya Udina volcano in Siberia is coming back to life. This Russian volcano situated along the dangerous Ring of Fire has shown so much seismic activity over the past few years that its classification has changed from extinct to active. Some scientists think that it could erupt at any time.

Millennia have vanished, taking species and ecosystems with it. Fossils restore the broken mosaic of prehistory, providing insights into how animals lived and died. Recent riddles included glass pearls inside clams, where butterflies got their legs from and a toe that continues to defy explanation.

At any point on the earth's surface, if you dig down far enough, you will come to rock. Rocks are the building blocks of the earth's crust. There are many different types of rock, and they are all composed of one or more minerals. This article explores 10 fascinating facts about rocks and minerals.

Mud is a versatile and interesting material. It's useful for both humans and animals. It can also be dangerous, especially in the form of mud volcanoes and mudflows.

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.
