Identifying Major Groups of Rocks and the Processes of their Formation 4 th Grade Science By: Jessica Whitlock
What are Rocks? What do you already know about rocks? Shape? Size? Different Kinds? Location? Made out of?
What are Rocks? Rocks are made up of a mixture of minerals and other materials. *Over 2500 Minerals that we know of* Rocks come in all shapes, sizes, and colors because there are formed from one of more minerals Rocks are formed in one of these three groups
Igneous Rocks Igneous is a latin word that means fire These rocks are formed when temperatures in earth’s crust begin to rise and magma begins to melt After the magma (Lava) cools and begins to harden igneous rocks are formed.
Melting Magma Cooling and Hardening Igneous Examples: -Pumice -Rhyolite
Sedimentary Rocks Igneous rocks turn into sediments due to weathering and erosion. When these sediments are compacted together sedimentary rocks are formed. Fossils form in sedimentary rocks Example: -Sandstone
Fossils are the remains of organisms that lived millions years ago. They are found in sedimentary rocks. Fossils help provide scientists with important evidence to help determine what happened in Earth’s history and when it happened.
Melting Cooling and Hardening Magma Igneous Weathering & Erosion Sedimentary Sediments Compacting
Metamorphic Rocks Sedimentary rocks become pushed down into the ground and heat and pressure changes them into metamorphic rocks. Some examples: -Slate - Marble
Guess the Rock? ? ? Metamorphic (Slate) Igneous (Pumice) Sedimentary (Lime stone)
The Rock Cycle -This is the ever changing process that rocks go through. Cooling and Hardening Igneous Melting Magma Rocks Weathering & Erosion Metamorphic Sediments Sedimentary Heat and Pressure Compacting
