Understanding the Rock Cycle: Types of Igneous, Sedimentary, and Metamorphic Rocks

Discover the fascinating world of rocks through the rock cycle! There are three main types of rocks: igneous, formed from cooling magma and lava; sedimentary, created by compacted sediments like sand and gravel; and metamorphic, which are transformed under heat and pressure. Learn about rock parts such as crystals and grains, helping you identify different rock types. Engage in a hands-on exploration by examining rocks with a partner and a magnifying glass. Together, observe the unique features that define each type of rock.

Presentation Transcript

  1. Lets Rock! The rock cycle

  2. 3 Types of Rocks There are 3 different types of rocks: • Igneous • Sedimentary • Metamorphic

  3. 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.

  4. 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.

  5. 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)

  6. The Rock Cycle

  7. Parts Of Rocks

  8. Rocks have many different parts • Rocks can be sorted into groups by looking at their parts. Some rock parts are: • Crystals • Grains

  9. Crystals • Crystals are different atoms that are formed in a pattern. They can be big or small, fat or thin.

  10. Grains • Grains are smaller pieces of rock or sediment. Grain size is something that is used a lot to help decide the rock type.

  11. Rock Explorers • Lets look at some rocks! • Get a partner and a magnifying glass • Come and pick up a rock (you will be looking at one rock at a time) • You and your partner will take turns looking at the rock. Decide if you think that crystals are large or small. Look to see if it has grains.
