Lesson Objectives Explain how igneous rocks are formed. Exposition: 1. Name some types of igneous rocks. Examples of Igneous rocks include Obsidian, Basalt, Granite and Gabbro 2. Describe the properties of igneous rocks. Properties of igneous rocks include: • rough • shiny • hard to very hard • do not react with acid Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified: • magma that cools slowly will form an igneous rock with large crystals • lava that cools quickly will form an igneous rock with small crystals This means that we get two main types of igneous rock, extrusive and intrusive, as shown in the table: Extrusive Intrusive Where the magma cooled On the surface Underground How fast the magma cooled Quickly Slowly Size of crystals Small Large Examples Obsidian and basalt Granite and gabbro Growing Together - Reaching Higher

Lesson Objectives Explain how igneous rocks are formed. Extrusive igneous rocks form from magma that erupted onto the surface as lava, where it cooled quickly. On the other hand, intrusive igneous rocks form from magma that cooled slowly, deep underground. 1. Explain how igneous rocks are formed. Igneous rocks are formed from molten rock that has cooled and solidified. The inside of the Earth is very hot - hot enough to melt rocks. Molten (liquid) rock is called magma. When the magma cools enough, it solidifies and igneous rock forms. Growing Together - Reaching Higher

Lesson Objectives Explain how igneous rocks are formed. CFU What are the properties of igneous rocks and name 2 examples? • Basalt and Granite are 2 types of igneous rocks. They are, rough, shiny, hard or very hard and do not react with acid. • Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified. Magma that cools slowly will form an igneous rock with large crystals. Lava that cools quickly will form an igneous rock with small crystals Growing Together - Reaching Higher

Lesson Objectives Explain how igneous rocks are formed. CFU There are 2 types of igneous rocks known as extrusive and intrusive igneous rocks. Extrusive rocks are magma that has reached the earth's surface (now known as lava) and has rapidly cooled. This has caused the crystals in this type of igneous rock to be small. However, Intrusive igneous rocks are formed when magma is forced into older rocks at depths within the Earth’s crust, which then slowly solidifies below the Earth’s surface so that large crystals form.

Lesson Objectives Explain how igneous rocks are formed. WGLL Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in the Earth's mantle or crust. The melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Intrusive igneous rocks form from magma that is forced into older rocks at depths within the Earth’s crust, which then slowly solidifies below the Earth’s surface so that large crystals form. Extrusive igneous rocks form when hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently. The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, so that there is little time for crystals to grow and so they are small or nonexistent.
