Chapter 4 : Rocks

Rocks - Mineral Mixtures

QuestionAnswer
A solid mixture of crystals of one or more minerals or other materials. Rock
The process by which one rock type changes into another rock type. The Rock Cycle
The hot liquid that forms when rock partially or completely melts; forms underground ; may include mineral crystals. Magma
Rock that forms in layers when sediments and fragments are compacted (pressed) and cemented together; may contain fossils. Sedimentary Rock
Rock that forms from extreme heat and extreme pressure ; changes the texture and composition of preexisting rock. Metamorphic Rock
Rock that forms from the cooling and crystallization of magma or lava. Igneous Rock
The minerals and elements a rock is made up of. Composition
The sizes, shapes, and positions of the grains that a rock is made of. (How it feels) Texture
The type of Igneous rock that forms when magma cools and solidifies beneath Earth's surface. Intrusive
The type of Igneous rock that forms when lava or pyroclastic material cools and solidifies on the Earth's surface. Extrusive
The layers of sedimentary rock that form from the deposition of sediment. Strata
The layering of Sedimentary Rock. Stratification
The texture of metamorphic rock in which mineral grains are lined up like the pages in a book. Foliated
The texture of metamorphic rock in which mineral grains are not lined up. Nonfoliated
The hot liquid that forms when rock partially or completely melts and is forced above ground. Lava
The steps that form Sedimentary Rock (4) 1) Weathering & Erosion 2) Deposition 3) Compaction (Pressure) 4) Cementation (Glue)
The steps that form Metamorphic Rock (2) 1) EXTREME heat 2) EXTREME pressure
The steps that form Igneous Rock (2) 1) Melting 2) Cooling & Crystallization
The type of Igneous rock that forms when magma cools and solidifies beneath Earth's surface. Intrusive
The type of Igneous rock that forms when lava or pyroclastic material cools and solidifies on the Earth's surface. Extrusive
The layers of sedimentary rock that form from the deposition of sediment. Strata
The layering of Sedimentary Rock. Stratification
The texture of metamorphic rock in which mineral grains are lined up like the pages in a book. Foliated
The texture of metamorphic rock in which mineral grains are not lined up. Nonfoliated
The hot liquid that forms when rock partially or completely melts and is forced above ground. Lava
The three types of texture a rock can have. 1) Fine grained 2) Medium grained 3) Coarse grained

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

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.

To see how well you know the information, try the Quiz or Test activity.
