THE ROCK CYCLE

THE ROCK SCIENTIST• Tom and Bob were partners on a project they have to do in science class. They had to

find the three types of rocks Igneous, Sedimentary, and Metamorphic. So they did a PowerPoint to show the three types of rocks and how they form.

IGNEOUS ROCK • Igneous rocks are form from lava cooling. Igneous rocks have little white crystals but

some rocks you can see and some don’t so you have to use a microscope. Igneous rocks can be found near volcanoes.

SEDIMENTARY ROCK• Sedimentary rock is form by weathered products of preexisting rocks. They also can be

formed by sediment compacted together. Sedimentary rocks can form underwater. Deposited eroded pieces of the earth can form together to make a sedimentary rock. Sometimes there are no crystals but when there are, the crystals are a little big.

METAMORPHIC ROCK• Metamorphic rocks are formed by heat and pressure combine together. Morph means

change so metamorphic changes from igneous and sedimentary. Metamorphic Rocks are grainy and they have really big crystals.
