All the processes that change rock from one type to another type
Rock Cycle
100
Rock that has been changed by pressure, heat, or very hot water.
Metamorphic Rock
100
The uppermost layer of soil, which is more crumbly than other soil layers.
Topsoil
200
Melted rock that has risen to Earth's surface.
Lava
200
Scientists use the ______________ which ranks minerals from 1 (softest) to 10 (hardest).
Mohs Hardness Scale
200
Forms when melted rock hardens.
Igneous Rock
200
Forms when layers of sediment settle over time and bind together.
Sedimentary Rock
200
The bottom soil horizon, mainly composed of rock.
Bedrock
300
A natural, solid substance with a definite chemical composition and physical structure.
Mineral
300
Betsy has a mineral that easily cleaves into layers. Which mineral is he likely to have?
Mica
300
Cools deep within Earth's Crust. Has a coarse texture made up of crystals.
Intrusive Igneous Rock
300
Cools on Earth's Surface. Finely grained...sometimes their is no time for crystals to form.
Extrusive Igneous Rock
300
Which soil layer would contain the most humus?
Topsoil
400
_________ is made up of one or more minerals.
Rock
400
Name four properties of minerals.
Streak
Fluorescence
Crystal Shape
Luster
Color
Cleavage
400
Sedimentary Rock is formed into two main groups----this type forms from rock that is broken into smaller pieces. A result of natural processes such as wind and rain weathering rock.
Clastic Formation
400
Sedimentary Rock is divided into two main groups based on how it is formed......this type is formed when chemicals in water come out of the water and form solids.
Chemical sedimentary rock
400
What would a farmer most likely do to prevent soil from blowing off a field?
Plant a row of trees.
500
The process by which metamorphic rock forms.
Metamorphism
500
A- scratches D; is scratched by B and C
B- Scratches A, C, and D
C- Scratches A and D; is scratched by B
D- What????
D is scratched by A, B, and C
500
What causes both igneous and metamorphic rock to form where a land plate meets and ocean plate?
Heat and pressure caused by the collision of the plates.
500
Metamorphism that takes place over a large area.
Regional Metamorphism
500
Topsoil contains a lot of iron....what is most likely the source of this mineral?
