Nij: So is igneous rock only found near volcanoes? Heather: No, you can find igneous rocks in lots of places. And that's because Earth used to be almost entirely molten. Kids: Like when dinosaurs were alive? Heather: Way before then. Nij: While we're down here, can we see the othe...
Igneous rocks are of two types, intrusive and extrusive. Intrusive igneous rocks are formed when the magma cools off slowly under the earth’s crust and hardens into rocks. Gabbro and granite are examples of intrusive igneous rocks. Rapid cooling results in smaller crystals while slow cooling res...
No, minerals vary in hardness; for example, talc is very soft, while diamond is the hardest known mineral. 10 What are minerals? Minerals are naturally occurring, inorganic solids with a specific chemical composition and crystalline structure. 7 What is a common example of a rock? Granite is...
What type of rock is equigranular? Equigranular Texture Rocks with equigranular ("EC-wi-GRAN-ular") have mineral grains that are generally the same size. This example is agranite. Is Basalt a Equigranular? An equigranular material is composed chiefly of crystals of similar orders of magnitude...
A rock with a similar composition and appearance as granite,gneiss, can form through long and intense metamorphism ofsedimentary(paragneiss) origneousrocks (orthogneiss). Gneiss, however, is distinguished from granite by its strong fabric and alternating dark and light colored bands. ...
