Which of the following forms igneous rocks? A. weathering of rock B. cooling of liquid magma C. heat and pressure changing solid rock D. compaction and cementation of loose material
What is B. cooling of liquid magma
100
Where are metamorphic rocks formed?
What is deep in the earth.
100
What type of rock can be foliated?
What is metamorphic rocks. Foliated means forms layers.
200
The grouping of things that are alike is known as
What is classification
200
Coal is a sedimentary rock formed from A. plants B. lava C. chemicals D. magma
What is A. plants - nonclastic sedimentary rocks
200
Magma that reaches the earth's surface is called ______.
What is lava
200
A metamorphic rock that has mineral crystals arranged in bands is ______. A. foliated B. unfoliated C. clastic B. nonclastic
What is A foliated (when metamorphic rock get heated and pressured into layers or bands)
200
What type of rock can be clastic or non-clastic?
What is sedimentary rocks. Clastic means formed by mechanical weathering.
300
Marble is formed from ___________.
What is limestone
300
What is the process that forms sedimentary rocks?
What is 1.deposition (stopping of sediments) 2. compression (pushing sediments down by weight from above) 3. cementation (sediments are glued together)
300
What is the process that forms igneous rocks?
What is the cooling of liquid magma (can be inside/intrinsic or outside/extrinsic of a volcano)
300
What is the process that forms metamorphic rocks?
What is rocks being pushed down into the earth and being exposed to heat and pressure.
300
Molten rock is made up of (hint: molten means melted!)
What is minerals
400
The series of natural processes by which rocks are slowly changed from one kind to another is _________. A. sedimentation B. the rock cycle C. classification D. petrology
What is B the rock cycle
400
What are the two features that can only be found in sedimentary rocks?
What are seashells and fossils! (remember sedimentary rocks are formed in or near water)
400
The mineral crystals of a rock formed from magma are usually ________. Why? A. small B. large C. fine D. cubic
What is B large because magma cooled inside of a volcano cools slower and forms larger chunks of minerals as it cools.
400
What are the two conditions needed for metamorphic rocks to formed?
What are heat and pressure?
400
Rocks formed from the remains of living things are classified as what type of rock?
What is sedimentary rocks.
500
Why is slate useful for roofing? What type of rock is slate?
What is slate is waterproof and it is metamorphic.
500
Which of the following would NOT be a process that preserves shells in sedimentary rocks. Why? (can be more than one choice!) A. pressing and melting B. melting and cooling C. heating and uplifting D. layering and compacting
What is A, B, and C. All of these involve melting or heating which are not part of the sedimentary rock formation process.
500
What is the most common intrusive AND extrusive igneous rock? (you need to label which is intrusive and which is extrusive)
What is granite (intrusive) and basalt (extrusive)
500
What types of rocks can be changed into metamorphic rocks?
What is sedimentary, igneous, AND metamorphic rocks
500
Limestone and halite are examples of ________. A. clastics B. nonclastics C. foliated rocks D. unfoliated rocks
What is B. nonclastics because they are formed through chemical and organic means.
