Rocks and Minerals Lets Rock!

Engage Is it a Rock (Version 2) Have the students so this on their own and then as a table Make copies and glue in notebooks

Explore Journal- List what you know about Rocks and Rock cycle Brain pop- Rock Cycle and Types of Rock Assign notes and vocab

Explain- The Earth’s crust is made up of 2 things: Minerals and Rocks Coal Gneiss Scoria Rocks are combinations of minerals Minerals are individual crystals of all the same stuff ***You should see lots of different minerals in every single rock

Minerals are….. Naturally occurring Nonliving Have specific chemical formula Quartz : SiO Emerald: Be3Al2Si6O18

In 2008, crystals up to 39 feet long were found in a cave in Mexico at a depth of 1000 feet. The cave is extremely hot, with air temperatures reaching 136 °F with 90 to 99 % humidity.

There are 3 Types of Rocks

Three Types of Rocks Rocks are classified by how they form Igneous Sedimentary Metamorphic Rocks can change from one type to another over time Schist

Rock Classification Rocks are classified by: How they form Texture Grain size Mineral composition Conglomerate Sedimentary Rock

Igneous Rock Igneous rocks are formed by magma and lava as it cools. Igneous rocks form in two different ways. Rock that comes from lava cools very fast and can either be very light and airy or the rocks can be glassy. Rocks that come from magma are formed under ground. They are often times very hard and have more colors.

Intrusive Igneous Rock Intrusive igneous: cooling takes place slowly beneath Earth’s surface granite

Extrusive Igneous Rock Extrusive igneous: cooling takes place rapidly on Earth’s surface Pumice

Igneous rock

Sedimentary Rock Sedimentary rock: forms from the compaction and/or cementation of sediments This process is called lithification Sediments are: Rock pieces Mineral grains Shell fragments Limestone

How do sediments form? weathering Sediments form through the processes of weathering and erosion of rocks exposed at Earth’s surface erosion

Sedimentary Rock con’t…. Sedimentary rock can also form from the chemical depositing of materials that were once dissolved in water When water evaporates, minerals are left behind and form rock gypsum

Sedimentary Rock Sedimentary rock is made when sediments (sand, gravel, and dirt) are pressed together over time and become a rock Sedimentary rock is formed in layers.

Sedimentary Rocks Limestone Shale Sandstone Granite

Metamorphic Rock Metamorphic rock: forms when any rock type is changed into a different kind of rock Changes due to great heat and/or pressure Gneiss

How does rock change? Rocks are heated, squeezed, folded, or chemically changed by contact with hot fluids marble

Metamorphic Rock Metamorphic rocks are made from other rocks. Heat and pressure help change an igneous or sedimentary rock into a new kind of rock (think about how a caterpillar becomes a butterfly)

The Rock Cycle

The Earth Recycles Rock The rock cycle is an ongoing series of processes inside Earth and on the surface Slowly changes rocks from one kind to another Any type of rock can change into another type

How does this relate to plate tectonics? Plate movement drives the rock cycle Subduction (1 plate pushed under another plate) Re-melts rock into magma Mountain building Folding, faulting, uplift Exposes rock at the surface to be weathered and eroded
