Happy Autumnal Equinox!!  Periods 1,2,4--Sign in to Edmodo and tell the class what you did over the break. Then glue in the rock cycle song.  3 rd period.

Do Now: Group your samples into two categories of your choice using their physical characteristics. (Avoid size and volume)

 Igneous rocks form when molten rock cools and solidifies. Molten rock is called lava when it is above the Earth’s surface and magma when it is below.

Igneous Rocks c. Classify rocks by their process of formation.

Aim: How are rocks classified? Do Now: In your notes answer the following questions. 1)What do you think rocks are made of? 2)How do you think scientists.

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.

Igneous Rocks

Look at the words below. Pick 3 words you don’t know, 2 words you do know, and come up with 1 word that describes all the words below.

form from the cooling of molten rock (lava and magma). Igneous Rocks form from the cooling of molten rock (lava and magma).

Are lava and magma the same? LAVA is molten material found on the surface of the earth. MAGMA is molten material found beneath the surface of the earth.

Classified by Formation: Extrusive Rock is formed from lava erupted onto Earth’s surface. Exits the Earth Basalt

Classified by Formation: Intrusive Rock is formed when magma hardens beneath Earth’s surface. Inside the Earth Granite

Classified by Texture: Fast Cooling Lava (Extrusive) Fine-Grained, small crystals, more smooth Slow Cooling Magma (Intrusive) Coarse-Grained, large crystals, more rough

An intrusive igneous rock would have what type of texture? Why? Coarse-Grained, large crystals. Smooth & rough. It is hotter in the earth than on the outside of the earth so it takes longer for magma to cool down.

An extrusive igneous rock would have what type of texture? Why? Fine-Grained or glassy texture It is cooler on the surface of the Earth so the rocks can cool faster.

Classified by Mineral Composition Mafic describes dark colored rocks because of magnesium and iron. Felsic describes light colored rocks because of feldspar and silicon

Mineral Composition Igneous Rocks Granite is made of: Feldspar, Mica, Quartz, Hornblende Rhyolite is made of: Obsidian is made of: Quartz, Iron, Magnesium

How do you use igneous rocks? Tools Gravel Buildings Cleaning Streets Polishing Bridges Gardening

Classify igneous rocks according to their formation. Where do they form AND made of magma or lava? Intrusive (magma) and Extrusive (lava) How do they cool? Slow = Large crystals Fast = Small or No Crystals What they are made of (mineral composition)? Mafic and Felsic

SAMPLE 1 = PUMICE SAMPLE 2 = ANDESITE SAMPLE 3 = OBSIDIAN SAMPLE 4 = GRANITE SAMPLE 5 = SCORIA SAMPLE 6 = GABBRO SAMPLE 7 = RHYOLITE SAMPLE 8 = DIORITE SAMPLE 9 = BASALT
