A mixture of minerals, rock fragments, volcanic glass, organic matter and other natural materials is known as this.
What is a rock?
100
Igneous rocks that are formed as lava cools on the surface of the Earth is known as this.
What are extrusive igneous rocks?
100
When mineral grains grow and rearrange, but don’t form layers, this texture results.
What is nonfoliated?
100
Intrusive igneous rocks would have this size of mineral grains due to slow cooling.
What is large?
100
Marble is an example of this type of rock.
What is a metamorphic rock?
200
A model that describes how rocks change over time is known as this.
What is the rock cycle?
200
Igneous rocks that are dense and dark colored are known as this.
What are basaltic rocks?
200
Loose materials such as rock fragments, minerals grains, and bits of shell that have been moved by wind, water, ice or gravity are known as this.
What are sediments?
200
Extrusive igneous rocks would have this size of mineral grains due to quick cooling.
What is small?
200
Gneiss is a metamorphic rock with parallel streaks in it. Thus, gneiss is said to be this type of rock.
What is foliated?
300
The type of rock that is formed when hot magma cools and hardens is known as this.
What is igneous rock?
300
Light colored igneous rocks of lower density than basaltic rocks are known as this.
What are granitic rocks?
300
This type of rock results when sediments are pressed and cemented together, or when minerals form from solutions.
What is sedimentary rock?
300
This type of rock is the result of rocks that cooled so quickly that few or no mineral grains formed.
What is volcanic glass?
300
Minerals that settle between sediments and keep them together are acting as this.
What is a cement?
400
This is the name of magma when it reaches the Earth’s surface.
What is lava?
400
Rocks that are changed because of changes in temperature and pressure or the presence of hot, watery fluids are known as this.
What are metamorphic rocks?
400
The process in which small sediments stick together and form solid rock is known as this.
What is compaction?
400
This type of rock have been transformed from igneous, sedimentary, and metamorphic rocks.
What is metamorphic rocks?
400
An example of a rock composed of organic matter is known as this.
What is coal?
500
Rocks that form from magma below the surface is known as this.
What is intrusive igneous rocks?
500
When mineral grains line up in parallel layers, the metamorphic layers are said to have this texture.
What is foliated?
500
This process occurs when minerals such as quartz, calcite, hematite are deposited between pieces of sediment and act as a glue holding sediments together.
What is cementation?
500
Sandstone is an example of this type of rock.
What is a sedimentary rock?
500
An exposed rock bank is shown to have many parallel layers that easily separate. It is likely that the rock in this bank is this type of rock.
