​3 Types of Rocks

Over the past few weeks we have been learning about 3 types of rocks: IGNEOUS, METAMORPHIC, and SEDIMENTARY.

​This section will review each rock type and how it is made. Pay close attention, there will be questions at the end!!!

• "Ignis" means fire in Latin

• This was the first rock on Earth​

• Gas bubbles can get trapped inside while the rock is cooling

• ​May contain crystals or have a shiny, glass-like surface

  ​

​Fun Facts

• Molten rock called MAGMA is under Earth's surface.

• It eventually comes through Earth's surface and turns into LAVA.

• The lava COOLS and HARDENS, turning into igneous rock ​

​How it's Made

IGNEOUS Rock​

• May contain FOSSILS, or evidence of past life

• Usually form in a water environment, like streams

• ​Usually soft and can crumble easily

• Contains layers and rounded grains ​

  ​

​Fun Facts

• First, other rocks are WEATHERED, or worn down.

• EROSION causes the weathered rocks to move by wind or water

• ​These pieces of rock, called SEDIMENTS, eventually stop moving and form layers. These become SEDIMENTARY rocks

​How it's Made

SEDIMENTARY Rock​

• "Morph" means change

• Can have visible layers that look "bent" or distorted

• One example of metamorphic rock is slate. They used to use slate to make blackboards.

  ​

​Fun Facts

• Formed inside the Earth due to HEAT and PRESSURE

• Come from existing rocks (sedimentary or igneous)

• These rocks ARE NOT LIQUID, the heat does not melt them

• They are MORPHED by heat and pressure​

​How it's Made

METAMORPHIC ROCKS Rock​

Review Time!!!

Now you are going to learn about the Rock Cycle! There will be questions throughout so pay close attention!

​The Rock Cycle

The rock cycle is the continuous (or non-stop) motion of rocks becoming new rocks. There is not a set start point, you can choose any of the 3 types of rocks and follow it to see what it turns into and how it eventually becomes itself again!!

Multiple Choice

The Rock Cycle is continuous, meaning it never stops.

• True

• False

Multiple Choice

You HAVE to always start with sedimentary rock when following the rock cycle.

• True

• False

​Let's start with IGNEOUS...

• Igneous rock can be formed when metamorphic rock or sedimentary rock MELT.

• When heat and pressure are applied to igneous rock, it forms a metamorphic rock ​

• When igneous rock goes through weathering and erosion, it turns into sedimentary rock ​

​

Multiple Choice

When igneous rock goes through heat and pressure it becomes...

• Igneous rock

• metamorphic rock

• sedimentary rock

Now SEDIMENTARY....

• Sedimentary rock can be formed when weathering, erosion, and finally cementation happens to igneous rock and metamorphic rock.

• ​When heat and pressure are applied to sedimentary rock, it forms a metamorphic rock.

• ​When sedimentary rock melts, it turns into igneous rock.

​

Multiple Choice

When sedimentary rock melts, it turns into

• Igneous Rock

• Sedimentary Rock

• Metamorphic Rock

Now METAMORPHIC....

• Metamorphic rock can be formed when heat and pressure are applied to igneous rock and sedimentary rock

• When metamorphic rock melts, it becomes igneous rock

• When metamorphic rock goes through weathering and erosion, it turns into sedimentary rock

Multiple Choice

What is needed in order for metamorphic rock to form?

• Heat and pressure

• Melting

• Weathering and erosion
