Presentation on theme: "Earth Science Chapter 4 Rocks!. Bellwork What is the most interesting thing you learned during your research? Write it down and then we will talk about."— Presentation transcript:
You do it! Read section 2 about igneous rocks. Create a classification chart describing how igneous rocks are classified Your chart should include information on origin, texture, and mineral composition of igneous rocks Charts should also include illustrations, all vocabulary words, and examples of igneous rocks
Bellwork What type of rock is created when lava is cooled quickly?
Igneous Rock Classification Origin On or beneath Earth’s surface Texture Depends on the size and shape of mineral crystals Mineral composition Dependent upon the amount of silica in the lava or magma
Origin Extrusive Rock: igneous rock formed from lava that erupted onto Earth’s surface Most common type is basalt Makes up most of the ocean’s floors
BELLWORK WHAT DID YOU FIND MOST INTERESTING ABOUT IGNEOUS ROCK FORMATION?
SEDIMENTARY ROCKS READ SECTION 3 WITH A PARTNER MAKE A FLOW CHART DESCRIBING THE FORMATION OF SEDIMENTARY ROCKS YOUR CHART SHOULD INCLUDE: – DEFINITION OF SEDIMENT – 4 STEPS OF THE PROCESS INCLUDING EXPLANATION – ILLUSTRATIONS
Sedimentary process ErosionDeposition CompactionCementation
Erosion Natural forces break down and carry small pieces of rock
CLASSIFY TYPES OF SEDIMENTARY ROCKS MAKE A CLASSIFICATION CHART DESCRIBING THE THREE MAIN TYPES OF SEDIMENTARY ROCKS CHARTS SHOULD INCLUDE DESCRIPTION OF ALL THREE TYPES HOW THEY FORM EXAMPLES ILLUSTRATIONS
Section 4 Read Section 4: How do coral animals live? How do coral reefs form? – Illustrate this as well as writing your answer. What evidence do limestone deposits from coral reefs provide about Earth’s history?
On your Own Read Section 5: 1. How are metamorphic rocks formed? 2. How do geologists classify metamorphic rocks? What are the different types of metamorphic rocks? Explain each. What are the uses of metamorphic rocks?
If you complete the worksheet.. Read section 6: The Rock Cycle 1. Make an illustration of the Rock cycle and describe the steps/changes that occur 2. Answer the questions from all three section assessments 3. You may work with a partner, but every student must have their own work to turn in
When you complete the questions Answer the questions from all three section assessments You may work with a partner, but every student must have their own work to turn in Due Tomorrow!
