Rocks Misc.
100
A natural, solid mixture of minerals or particles is called this.
What is a rock?
100
Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface is called this.
What is an intrusive igneous rock?
100
The rock material that is broken down into smaller pieces or dissolved in water as rocks erode is called this.
What is sediment?
100
Molten rock material found under Earth's surface is called this.
What is magma?
100
All minerals are rocks but, not all rocks can be minerals. Name the texture of rock that makes this statement true.
What is biochemical.
200
The type of rock that forms from magma or lava cooling and crystallizing (or solidifying) is termed this.
What is igneous rock?
200
This type of igneous rock is formed from lava ON the earth's surface that cools and solidifies.
What is an extrusive igneous rock?
200
The physical (mechanical) and chemical processes that change objects on Earth’s surface over time are called this. In other words, this process breaks rocks into small fragments.
What is weathering?
200
A rock transforms to sediment by these two processes.
What are weathering and erosion?
200
This type of rock may be identified by observing the arrangement of the grains which often appear as bent or twisted layers or bands of crystals.
What is a metamorphic rock?
300
The fragments that make up a sedimentary rock are called this.
What are grains or sediments?
300
This intrusive igneous rock has larger, intergrown crystals and is the type of rock that Stone Mountain is primarily composed of.
What is granite?
300
The process that squeezes out fluids and decreases the space between the grains in a sediment deposit is called this.
What is compaction?
300
Prior to becoming igneous rock, this process must occur to any rock.
What is melting?
300
The laying down or settling of eroded material is called this.
What is deposition?
400
The grain size and the way grains fit together in a rock are called this.
What is texture?
400
This type of extrusive igneous rock is black with a glassy texture.
What is obsidian?
400
The crystallization of minerals from water into the spaces between sediment grains that makes sedimentary rocks stick together is called this.
What is cementation?
400
Metamorphic rocks are created by these two primary forces.
What is extreme heat and pressure?
400
This type of weathering involves processes by which rock is broken into smaller pieces.
What is physical (or mechanical) weathering?
500
The series of processes that change one type of rock into another type of rock is called this.
What is the rock cycle?
500
This igneous rock is very light and can float in water. It also has holes due to the release of gases and is used as an abrasive.
What is pumice?
500
The removal of weathered material from one location to another is termed this. In other words, this process moves the weathered fragments of rock material.
What is erosion?
500
If a rock goes through melting, solidification and exposed to heat & pressure then weathered and eroded and deposited what is this substance called.
What is sediments?
500
This type of weathering involves processes by which the materials in a rock are changed into new materials.
What is chemical weathering?
