Lecture 3 Igneous Rocks
... Igneous Rocks are classified by Texture and Composition – BOTH are used. Figure 4.3 (located below‐ in these notes) shows a general igneous rock classification which includes basic igneous rock types. Texture refers to the size and arrangement of crystals, glass and pyroclasic material in a rock. ...

... When geologists talk about plates they mean a large, rigid slab of solid rock. The word tectonics comes from Greek and translates to "to build." If we put these two words together, we get the term plate tectonics and this is the theory geologists use to explain how the Earth's surface is built up. T ...

Layers of the Earth
... The earth is made up of 3 main layers, which are comprised of sub-layers. The outermost layer of the Earth is the crust. It is like the peel of an apple. It is very thin compared to the other layers. The crust is only about 3-5 miles (8 km) thick under the oceans (oceanic crust) and about 25 miles ( ...
