This is a naturally occurring solid mixture composed of minerals, small rock fragments, organic matter, or glass.
What is rock?
100
This material, also called molten rock while inside the earth.
What is magma?
100
Rock and mineral fragments that are loose or suspended in water, mineral or organic matter deposited by water, air, or ice are called.
What are sediments?
100
Metamorphic rocks form when parent rocks go through this process.
What is squeezed, heated,or exposed to hot fluids.?
100
Cement is made from limestone, which contains tiny sediments this is known as what type of rock.
What is sedimentary rock?
200
This rock type builds up in layers.
What is sedimentary rock?
200
This type of molten rock erupts onto Earth’s surface.
What is lava?
200
The process by which rock sediments are removed and transported away by water, wind, or ice.
What is erosion?
200
Each metamorphic rock has one of these.
What is a parent rock?
200
This type of rock, through cooling and hardening, forms glass.
What is igneous rock?
300
A rock type formed underground, through heat and pressure.
What is metamorphic rock?
300
This process or processes in molten rock creates igneous rock.
What is cooling and hardening?
300
The conditions in the air above the Earth such as wind, rain or temperature, especially at a particular time over a particular area.
What is weather?
300
This results when uneven pressures cause flat minerals to line up, giving the rock a layered appearance.
What is foliation?
300
Rocks that are squeezed, heated, or exposed to hot fluids create rocks like marble that are commonly used to make statues.
What is metamorphic rock?
400
These are the individual particles in a rock.
What is grain?
400
The rate at which lava cools controls the size of this within igneous rocks.
What is crystals or crystal formation?
400
The process by which unconsolidated material converts into coherent, solid rock, through compaction or cementation; this process turns sediment into rock.
What is lithification?
400
In this process the rocks do not melt. They remain solid, but the texture and, sometimes, the mineral composition of the parent rock change.
What is metamorphism?
400
This process creates sedimentary rock, through compaction and/or cementation.
What is lithification?
500
Earths most abundant rocks, formed from melted rock that cools and hardens.
What is igneous rock?
500
Geologists classify igneous rocks by this; it refers to grain size and grain arrangement.
What is texture?
500
This process physically breaks rocks down into smaller and smaller pieces while another process involves a reaction with water that decomposes rock into smaller pieces.
What is mechanical weathering and chemical weathering?
500
The most obvious characteristic in metamorphic Rocks but not present in all metamorphic rocks.
What is foliation?
500
Over thousands of years, each type of rock can change into one of the others, this process is called.
