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.
Other Answer Choices:
Intrusive igneous rocks
Extrusive igneous rocks
Metamorphic rocks
Sedimentary rocks

Question 12
12.

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

Warm Up: Rocks are classified by how they formed. The three types are:
  • Igneous rocks form from cooling magma or lava.
  • Sedimentary rocks form from the bonding of rock fragments such as sand, silt, or clay; from organic materials; and from chemicals dissolved in water.
  • Metamorphic rocks form when other rocks are changed by heat and pressure.
In which type of rock would you expect to find each of the following?
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
Part 1: Classify rocks as igneous, sedimentary, or metamorphic.

The three groups of rocks each have unique characteristics. For example, many igneous rocks have a texture of interlocking mineral crystals. Sedimentary rocks may have distinct layers of sediments, known as strata.

To learn other characteristics of igneous, metamorphic, and sedimentary rocks, turn on Show common characteristics in the CHARACTERISTICS pane.

Match each rock type to its common characteristics.
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.
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.

Drag the rocks from the SIMULATION pane to the correct positions on the LOCATION tab. Click on the Status check box to check your placements as you go.

Each rock is labeled with a letter when you put your cursor on it. Record your findings by sorting the rock samples into the appropriate area.

Hint: there are 4 samples per type
