100
How are sedimentary rocks formed?
WEDCC
100
What types of climates have more chemical weathering?
hot, wet climates
100
What is the difference between erosion and deposition?
Erosion is the moving of soil and rock particles, and deposition is the placement of soil and rock particles in a new place
100
Which type of seismic wave travels the fastest?
P-waves
200
Which mineral is used in watches and computer chips?
Quartz
200
How are metamorphic rocks formed?
heat and pressure
200
Name 2 factors that affect weathering and describe how.
slope, burrowing animals, pollution, surface area, etc.
200
What is the greatest agent of erosion?
running water
200
Which type of seismic wave can only travel through solids?
S-waves
300
Why is a streak test a much more reliable way to identify a mineral than surface color?
surface color can change with rusting, wetting, etc., but streak color will always be the same
300
How do igneous rocks form?
heating and cooling
300
What is the type of weathering that causes rust from oxygen combining with iron-bearing minerals?
oxidation
300
What is a finger-shaped deposit at the mouth of a river?
a delta
300
What type of seismic wave causes the most damage?
surface waves
400
Name and describe 3 tests used to identify minerals (besides streak test).
varies
400
What is black volcanic glass that cools quickly (so no crystals)?
obsidian
400
Name the 3 main particles found in soil?
sand, silt, clay
400
What is a ridge-like deposit of sediments on a floodplain?
a leevee
400
Why do earthquakes and volcanoes tend to occur in the same places?
they both often occur along tectonic plate boundaries
500
Define independent variable, dependent variable, control group, and constants.
independent variable-the variable the experimenter changes dependent variable-changes as a result of the dependent variable changing control group-a group that receives no treatment/is the norm or standard to compare to constants-everything in the experiment that must stay the same (except for the independent variable)
500
How is the rock cycle a cycle?
any rock can change into any other type of rock given the right conditions
500
Name and describe two methods used to conserve soil.
varies
500
What type of deposit occurs when rills become wider and deeper?
gullies
500
What is a "hotspot" and why does it produce volcanoes?
It is a thin spot in the earth's crust where magma is pushed out
