Igneous rocks, sedimentary rocks, and metamorphic rocks
100
If an igneous rock, such as obsidian, cools very quickly, how would you describe its texture?
It's texture would be smooth and shiny texture like a thick piece of glass.
100
What is texture?
Texture is the look and feel of rock's surface.
100
What type of rock is sandstone?
Sedinmentary and in the group of clastic rocks.
200
How do igenous rocks form?
Igneous rocks form from cooling of magma or lava.
200
What does erosion mean?
Erosion means water, ice, wind, or gravity moves weathered rock or soil.
200
What kind of rock is chalk?
organic
200
How does sandstone form?

is the process by which sediment settles out of the water or wind carries it. Sediment is laid down in new locations.
300
Where do most metamorphic rock form?
Beneath Earth's surface
300
Which type of rock is formed under heat and pressure of the mantle?
Metamorphic
400
What does the term "coarse-grained" mean?
Coarse-grained means that magma cooled slowly forming rocks with large crystals.
400
What is cementation?
Cementation is the process which dissolved minerals crystallize and glue paricles of sediment together.
400
Describe the conditions under which metamorphic rocks form.
The condition under which metamorphic rocks form is heat and pressure.
400
Which type of rocks form through the process of cooling magma or lava?
Igneous Rocks
500
What does the term "Fine-grained" mean?
Fine-grained means that lava cooled rapidly forming igneous rocks with small crystals.
500
List the characteristics used to identify a rock.
mineral composition, color, and texture.
500
Describe the rock cycle.
A series of processes on Earth's surgace and in the crust and mantle that slowly change rocks from one kind to another.
