Properties of Igneous Rocks. Types of Igneous Rocks  Plutonic / Intrusive: These rocks formed from magma that crystallized and cooled slowly underground.
IGNEOUS ROCKS Lava is molten rock found at or near Earth’s surface. Magma is molten rock found beneath Earth’s surface. Igneous Rocks form from both lava.
Aim: How are Igneous Rocks formed? Do Now: Take out your ESRT and turn to page 6. Look at the chart called Scheme for Igneous Rock identification and answer.

Hot rocks/Fire Rocks Igneous comes from Latin and means “fire”.
Intrusive igneous rocks are formed beneath earth’s surface from magma Are coarse grained, made up of large, visible crystals that grow together The larger.

Igneous Rock...

Two types of molten rock: Igneous Rocks Felsic Mafic High in silicates Low in silicates slow flowing light color fast flowing dark color Molten Rock: Rocks made:

Igneous Rocks Felsic Mafic Granite Hornblende

Above the surface − Extrusive or volcanic. − Cools and solidifies quickly. − Crystals with small grain size or no crystals at all (glass). − Can also show air gaps from bubbles. Relatively light. Igneous Rocks Form in 2 places:

Igneous Rocks Below the surface − Called intrusive or plutonic. − Cools and solidifies slowly. − Shows crystals with large grain size.

Volcanic Rock Plutonic Rock

Igneous Rocks Descriptive Terminology of Rock Texture Texture: the size, shape, and arrangement of the mineral crystals in the rock. Porphyry: Large crystals are surrounded by a fine-grained mass of rock. It can also have bubbles. Frothy: Rocks with no crystals/minerals visible. Has many air gaps (bubbles) and has a foamy appearance.

Igneous Rocks Descriptive Terminology of Rock Texture Fine Grain: Small, barely visible crystals. Seen with the aid of a magnifying glass. Coarse Grain: Large crystals, visible with the un-aided eye, of various minerals in the rock together. Glassy: Rocks with no crystals and a clear or translucent appearance.
