What rock is thought as the parent rocks for all other rock types?
Igneous rock
Sedimentary rock
Metamorphic rock
Which of the following is NOT one of the three types of rock?
Igneous rock
Magma
Metamorphic rock
Sedimentary
Fossils are found in this type of rocks
Igneous rock
Sedimentary rock
Metamorphic rock
The interlocking crystals of igneous rock help to classify it since these crystals are evidence of how the rock formed. The crystals are a result of______
Chemical reactions of minerals
Sediments being deposited
Metamorphic rock
melted rock that cooled.
What type of rocks are formed from sediments over long period of time?
Igneous rock
Sedimentary rock
Metamorphic rock
Which of the following processes is one of the first steps in the formation of some sedimentary rock?
Rock is broken down into pieces.
Rock melts deep underground.
Liquid magma cools and hardens.
Minerals change due to pressure.
What type of rocks are formed from sediments over long period of time?
Igneous rock
Sedimentary rock
Metamorphic rock
In order to be classified as metamorphic, a rock must–
be made of small bits of larger rock.
have formed very quickly.
have been completely melted.
change with heat and pressure.
Igneous and metamorphic rock can be buried and undergo tremendous heating and stress. What is the process of transformation of one rock into another?
Compaction
Lithification
Metamorphism
Weathering
What is one of the most common processes that turns sediments into sedimentary rocks
Organisms in the soil breaking down organic matter into useful chemicals
Layers made of bits of broken rock pressing down on other layers
Minerals within rock layers growing into large crystals over time
Magma cooling under the surface of Earth, crystallizing to form rock
What is a natural process that causes one kind of rock to change into another kind?
Weathering
Rock cycle
Metamorphism
Sediments
Each rock type can follow only one pathway of the rock cycle.
True
False
Igneous rock is divided into two groups, extrusive and intrusive. Extrusive igneous rocks form when magma makes its wat to its surface as lava and the cools forming rocks, Which of the following will be the characteristics of the crystals?
Crystals are very large
Crystals have coarse grained
Crystals have a very fine texture
Crystals are smaller and are fine grained
Which rock is formed form the cooling of volcanic ash on Earth's surface?
Intrusive Igneous Rock
Extrusive Igneous Rock
Foliated Metamorphic Rock
Organic Sedimentary Rock
Which of the following processes produces metamorphic rocks?
Rapid burial
Gradual cooling
Extreme pressure
Regular deposition
True or False: A metamorphic rock that has grains arranged in bands is said to be non-foliated.
True
False
True or False: Once a rock is sedimentary, it cannot become an igneous rock.
True
False
