Powerful magma eruptions brought the diamonds to the surface, creating kimberlite pipes. Kimberlite is named after Kimberley, South Africa, where these pipes were first found. Most of these eruptions occurred between 1,100 million and 20 million years ago. Kimberlite pipes are ...
The kiddos are going to want to do this one over and over again! Pin What is a Volcano? The easiest definition of a volcano is a hole in the earth, but we recognize it as a landform (usually a mountain) where molten rock or magma erupts through the earth’s surface. There are two...
The three main types of rocks on the Earth’s surface are Igneous, Metamorphic, and Sedimentary rocks. Here’s a little bit more about them. What are Igneous Rocks?Igneous rocks are made from magma from the earth’s core or other rocks that have melted, crystalized, cooled, and hardened....
Dry steam geothermal power plants use steam that is brought from below the earth's surface through pipes, directly to the power plants turbines. Flash steam geothermal power plants use hot water that is brought from below the earth's surface. The hot water is sprayed into a tank and creates...
They are thought to have been brought to the earth’s surface by tectonic plate movement during mountain building processes. Another tectonic process called subduction occurs when one tectonic plate moves under another and is forced to sink, due to gravity, into the mantle. Organic carbon is ...
If you want to witness up close fire and heat collide as the magma flows out of the earth, becoming the hot, orangey substance more popularly known as lava, Hawaii is definitely the place to be. A living proof of the splendid power of nature to create life out of mere rocks, fire, ...
Thunder is the first dragon to have been seen by any of the adult humans atICARIS. The sounds and noises that are used for Thunder, his Father, and the Elder are the same croons and growls used for Toothless. Reminiscent to his ancestor, Toothless, Thunder has an archenemy whom he encoun...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
Diamonds are most often found in kimberlite pipes, carrot-shaped, volcanic rock formations. Diamonds started out as carbon that crystallized deep in the earth under great pressure and temperature. Volcanic activity brought the diamonds to the Earth’s surface in kimberlite magma. Erosion of kimberlite...
leading to a deficit of surface water along the equator in the ocean. The ocean then balances this deficit by bringing equatorial deep water up from the ocean floor, which transports nutrients to the surface, feeding organisms that thrive in equatorial regions, and leave their remains on the eq...
