Rock Stack

Notes to study for science test.

QuestionAnswer
What is a rock? A naturally formed, solid chunk of the Earth that is usually made up of one or more types of minerals.
What are the three types of rocks? Igneous rocks, Sedimentary rocks, and Metamorphic rocks.
Igneous rocks are formed by what? Volcanoes-they form when magma cools.
What are the two types of Igneous rocks? Intrusive (inside the Earth) and Extrusive (on the ground) rocks.
Slower cooling means more what? More crystallization.
Sedimentary rocks are formed by what? Sediments of other rocks-they are deposited at the same place and held together by "glue".
How are particles deposited? Water, wind, rain, and glaciers.
Where are Sedimentary rocks built up? On land and underwater.
Metamorphic rocks are formed by what? Rocks that have been changed by heat, pressure, or both-atoms from rocks break apart and reorganize themselves.
What are the two types of Metamorphic rocks? Foliated (you see bands) and Non-foliated (you don't see bands) rocks.
What are two examples of Igneous rocks? Granite and Basalt.
What are two traits of Igneous rocks? Crystallization and air pockets.
Do rocks closer to the surface cool slower or faster? Faster.
What are three examples of Sedimentary rocks? Sandstone, Limestone, and Shale.
What are four traits of Sedimentary rocks? Crystals, layering, shells, and fossils.
How do Sedimentary rocks react to acid? Sandstones rocks absorb the acid. Acid fizzes when it hits Limestone, but Shale has no affect on acid, or vice versa.
What are two traits of Metamorphic rocks? Mica and recrystallization.
What are two examples of Metamorphic rocks? Schist and Gniess.

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
