100
The look and feel of the rock.
What is the rock's texture?
100
Most metamorphic rock forms here.
What is deep underground?
100
The three major groups of rocks.
What is igneous, metamorphic, and sedimentary?
100
The series of processes that change rock from one type to another
What is the rock cycle?
100
True or False Coal is a type of organic rock.
What is true?
200
Which of these are NOT a sedimentary rock? a. granite b. conglomerate c. sandstone d. limestone
What is a. granite?
200
Slate is basically a denser, more compact version of what?
What is shale?
200
Which of the following is an igneous rock? a. marble b. basalt c. gneiss d. limestone
What is b. basalt?
200
Erosion and deposition play roles in the formation of this rock.
What is sedimentary rock?
200
True or False. Basalt is the most common intrusive rock.
What is False, extrusive?
300
Igneous rocks may be similar in mineral composition and yet have different what?
What is different textures?
300
The minerals that make up most of Earth's crust are called what?
What are rock-forming minerals?
300
The names of the three major groups of rocks refer to what?
What is how the rock formed?
300
The process in which dissolved materials crystallize and glue particles of sediment together.
What is cementation?
300
This rock has large crystals surrounded by smaller crystals.
What are porphyry rock?
400
True or False Plate movements help to drive the rock cycle.
What is true?
400
Metamorphic rocks that have their grains arranged in parallel bands are said to be this.
What is foliated?
400
These rocks form when minerals are dissolved in a solution crystallize on Earth's surface?
What are chemical rocks?
400
True or False. The process that presses sediments together is called deposition.
What is False, compaction?
400
Which would have larger crystals, an igneous rock formed from magma that cooled deep below the surface or an igneous rock that cooled from lava on the surface?
What is an igneous rock formed from magma that cooled below the surface because it had cooled slowly.
500
What characteristics do geologists use to identify rocks?
What is a rock's color and texture and determine its mineral composition?
500
True or False. Sandstone that began as coral can be found on continents.
What is False, Limestone?
500
A sedimentary rock that forms when rock fragments are squeezed together.
What is clastic rock?
500
How do metamorphic rock change into sedimentary rock?
What is metamorphic rock could be exposed at the surface and worn away. Erosion would carry particles of that rock to another place, where the particles would be deposited. Compaction and cementation could then change the sediment into sedimentary rock?
500
Explain how plate movements are related to the rock cycle.
What is plate movements start the rock cycle by helping to form magma, the source of igneous rocks.
