ROCKS. Chapter 6. What is a Rock?. The material that makes up the solid parts of Earth is known as rock . Geologists classify rocks into three major types by the way the rocks form. Igneous Sedimentary Metamorphic. Igneous rock forms when magma, or molten rock, cools and hardens.By satya

Igneous Rock. Chapter 2 section2. Origins of Igneous Rock. Begins as magma Magma can form When rock is heated Pressure is released Rock changes composition When magma cools it solidified or becomes hard Magma has many different minerals with different melting points.
Igneous Rock. September 12, 2011. Is That a Fact!. Igneous rocks that form deep underground are called plutonic rocks , after Pluto, the god of the underworld in Roman mythology. Volcanic rocks are named after Vulcan, the Roman god of metalworking and fire. Bellringer.
Igneous Rock. (from fire). Extrusive: Volcanic glass (Obsidian). Extrusive: Basalt ( o cean floor; ridges). Extrusive: Pumice (volcanic explosions). Intrusive : Granite (course crystals). Intrusive: Dykes. Metamorphic. Changed Rock. Metamorphic : Gneiss (Compressed Granite).
Igneous Rock. Igneous Rock. Igneous rocks form when magma (beneath the surface) or lava (reaches the surface) cools and hardens Igneous comes from the Latin word ignis , which means fire There are two types of igneous rock, intrusive and extrusive. Intrusive Igneous Rocks.
Igneous Rock. Earth Science Chapter 3 Section 2. Introduction. Igneous rock is sometimes called volcanic rock Igneous rock forms when magma cools and hardens (crystallizes). Formation of Igneous Rock. Most igneous rock forms from magma deep below the earths surface.
Section 6.2. Igneous Rock. Objectives. Summarize the three factors that affect whether a rock melts. Describe how the cooling rate of magma and lava affects the texture of igneous rocks. Classify igneous rocks according to their composition and texture.
Do Now: Name as many types of Igneous Rocks you know…. Igneous Rocks: Igneous Rock. Objectives. Summarize three factors that affect whether rock melts. Describe how the cooling rate of magma and lava affects the texture of igneous rocks.
Igneous Rock Lab. Goals of the lab. Observe the different textures of igneous rocks. Observe the differences in colors of igneous rocks. Based upon your observations of textures and colors, make inferences about the magma from which these rocks have been formed.
