Rocks! Objective: define and describe the three types of rocks What is a rock? A rock is a group of minerals bound together A rock can be composed of any number of minerals (at least 2) Rocks can be classified into three types: 1. Igneous 2. Sedimentary 3. Metamorphic Take 2 minutes to write down all observations about this rock Igneous Rocks Formed by the cooling of magma and hardening of hot, molten magma from inside the Earth. Take 2 minutes to write down all observations about this rock Sedimentary Rock Formed by the compaction and cementing of layers of sediments. Sediments are materials such as rock fragments, plant and animal remains and minerals that settle out of solution onto lake and ocean bottoms. Take 2 minutes to write down all observations about this rock Metamorphic Rock Formed by the effect of heat and pressure on other rocks Metamorphic rocks typically have foliations, which are parallel bands running through the rock
