Part 2: Where do different kinds of rocks form?

Igneous rocks that form under Earth’s surface are called intrusive. Intrusive igneous rocks usually have large mineral grains because they form from magma that cools slowly. Igneous rocks that form above ground are extrusive. 

Extrusive igneous rocks have small mineral grains or no grains at all because they form from lava that cools quickly.  

Heat and/or pressure underground causes the minerals in metamorphic rock to form bands or become "cooked."  

Sedimentary rocks form where sediments (pebbles, sand, silt, clay) form layers.

Move your cursor over the rock pictures. Based on what you see, classify the rocks by dragging them into the correct box on the CHARACTERISTICS tab. Click on Status to check your answers.

Once you have successfully classified each rock, put each rock below into the appropriate category.

In your own words, compare igneous, sedimentary, and metamorphic rocks.

What type of rock does cooled magma form?

Categorize the characteristics of extrusive and intrusive igneous rock

Draggable item		Corresponding Item
Sedimentary rocks		Air pockets, or vesicles, formed in rapidly cooling magma or lava
Metamorphic rocks		The remains of ancient plants and animals (fossils)
Igneous rocks		Foliation (layered or banded texture) from minerals flattened by heat and pressure

Draggable item		Corresponding Item
Metamorphic rocks		Formed from cooled magma. Texture of interlocking crystals with no layering or color banding. Some igneous rocks contain small holes or vesicles
Igneous rocks		Formed of particles such as pebbles, sand, silt, or clay cemented together. May contain fossils. Often form in layers.
Sedimentary rocks		Formed from rocks transformed by heat and/or pressure. Interlocking crstal texture often shows foliation (layewrs) or alternating light and dark bands.
