Monday, May 04, 2015 The Earth’s Crust Rock Families Igneous Rock
Rock Families #1 Igneous Fire Rocks There are three rock families: #2 Sedimentary Water Rocks #3 Metamorphic Changed Rocks
1. Igneous Rock Igneous Rock - “Born of Fire” Igneous rock forms from melted rock (lava or magma) when it cools.
Lava – melted rock that is found outside (“on”) the Earth’s crust
Magma – melted rock that is found inside the Earth’s crust
Magma – melted rock that is found inside the Earth’s crust Lava – melted rock that is found outside (“on”) the Earth’s crust Lava sampling
When lava and magma cool, they form two different kinds of Igneous rock: 1. Intrusive rock – igneous rock that is formed from cooled magma (e.g. granite)
2. Extrusive rock – igneous rock that is formed from cooled lava (e.g. pumice)
The main difference between intrusive and extrusive rock is their crystal size, which depends on how quickly they cool.
Intrusive rock (from magma) cools very slowly inside the Earth’s crust and forms large crystals. Extrusive rock (from lava) coolscools quickly quickly and forms small crystals.. Igneous rock video
Examples of Igneous Rock: Granite Pumice Obsidian Basalt
Igneous Rocks Hot rocks/Fire Rocks Igneous comes from Latin and means fire.
