The Rock Cycle - Mrs. V. Murphy's Science Class

The Rock Cycle The Rock Cycle is the natural process that rocks in the Earth's crust go through, that involves them continuously transforming into

igneous, sedimentary, and metamorphic rocks. What is a Rock? Naturally Occurring (not man made) Solid

Mixture of minerals and organic matter What makes a rock different from a mineral? Rock Both

Mineral Made of one or more minerals Solid Made of 1 type of element

Random crystal or no crystal structure Naturally Occurring Orderly crystal structure Quartz Granite = Feldspar

Muscovite Types of Rocks Sedimentary: Sandstone Metamorphic: Gneiss

Igneous: Diorite Igneous Rocks Igneous Rocks are formed from Magma and Lava Igneous rocks are classified by where they form

Intrusive forms when magma cools in the Earth vs . Extrusive

forms when lava cools on Earths surface Intrusive Vs. Extrusive Diorite Granite

Basalt Pegmatite Gabbro Rhyolite

Andesite Scoria Igneous Rocks: Crystal Size and Cooling Time Location of Rock Crystal Size

Intrusive (in earth) Extrusive (earth surface) Large crystals Small crystals

Longer cooling time Shorter cooling time Picture Cooling time Sedimentary

Rocks Sedimentary Rocks form from sediment or rock particles Sediment is material that is deposited by air, water, or ice. These materials can be: tiny pieces of rock broken minerals

pieces of plants and animal remains How do sedimentary rocks form? Sediments pile on top of each other on land or in water. As sediments pile, they become compacted and cement together. This forms cemented layers of sediment.

Sedimentation Process Sedimentary Rock Layers Sedimentary Rock Layers Some rocks form from

plants or shells Coal- created from the remains of plants (dead wood, bark, leaves, stems, and roots) The coal we use today started forming millions of year ago in swamps Limestone- created from the shells and skeletons of ocean organisms.

Limestone Formation Metamorphic Rocks Metamorphic Rocks Extreme heat and pressure can change rocks.

The original rock is called the parent rock The new rock formed is called the metamorphic rock Heat and pressure change the structure of the parent rock and their minerals recrystallize Examples of

Metamorphic Rocks Extreme heat and pressure Parent Rock Shale Metamorphic Rock Slate

Examples of Metamorphic Rocks Extreme heat and pressure Parent Rock Limestone

Metamorphic Rock Marble Examples of Metamorphic Rocks Extreme heat and pressure Parent Rock

Mica Metamorphic Rock Phyllite When a rock forms, does it stay that way forever? NO!!!!!!

Rocks are always changing by processes like: Weathering Melting Erosion Cooling Compaction Cementation

Composition of Igneous Rocks Igneous rocks are mainly composed of silicate minerals (quartz, feldspar,etc.) Rocks with high silicate levels-are typically light in color ex: granite, rhyolite Rocks with low silicate levels- dark in color

ex: gabbro and basalt IGNEOUS ROCKS BASALT RHYOLITE Composition of Igneous

Rocks Igneous rocks are mainly composed of silicate minerals (quartz, feldspar,etc.) Rocks with high silicate levels-are typically light in color ex: granite, rhyolite Rocks with low silicate levels- dark in color ex: gabbro and basalt

Igneous rocks make long-lasting landforms 1. Intrusive rock formations-as magma pushes up toward Earths surface, it makes channels and other formations underground. 2. Extrusive rock formations builds plateaus when erupting from long crack gently sloping volcanoes (Hawaiian islands) cone-shaped volcanoes

(1). contains greater amount of silica (2). erupts explosively (3). Mount St. Helens is an example RECAP: Rock cycle-the set of natural processes that form, change, break down, and reform rocks

Our world is built of rocks Rocks have many purposes 1. used to build houses and skyscrapers 2. great source of metals 3. used to carve statues and other works of art
