What is the difference between nonrenewable and renewable resources?
Renewable - those that can be replaced or never runs out.
Nonrenewable - those that cannot be replaced at the same rate it is being used.
What are the 2 types of waves?
Mechanical & Electromagnetic
What is the Law of Superposition?
When sedimentary rock layers are deposited, younger layers are on top of older rock layers.
What is convection?
cool material sinks as hot material rises due to
DENSITY
What is the difference between high and low pressure?
High - pressure weather system brings clear skies and fair weather.
Low - pressure weather system brings clouds, precipitation, and storms
List the 4 nonrenewable resources & 5 renewable resources
Nonrenewable: Coal, Oil, Natural Gas, & Nuclear Energy
Renewable: Wind, Geothermal, Biomass, Solar, Hydroelectric

Explain the movements of all 3 plate boundaries?
Convergent - two plates colliding with each other
Divergent - two plates moving away from each other
Transform - two plates sliding horizontally past each other

What are the parts of a compressional wave?
Compression and Rarefaction
Explain how ALL 3 rocks form
Sedimentary - Weathering & Erosion AND Compaction & Cementation

What are the parts of a transverse wave?
Crest, Trough, Wavelength, Amplitude
Explain the difference between absolute & relative dating
Absolute: Determines exactly how many years old something is
Relative: Determines if one thing is younger or older than another
Explain what the 3 types of convergent boundaries form
Continental vs Continental - folded mountains
Oceanic vs Continental - volcanic mountain range
Oceanic vs Oceanic - arcs of volcanic islands
Some natural disasters can be predicted, name the technology used to predict the following: Hurricanes, Earthquakes, Tsunamis, & Tornadoes
Hurricanes - Saffir-Simpson Scale
Earthquakes - Richter Scale
Tsunamis - DART (Deep-Ocean Assessment & Reporting)
Tornadoes - Fujita Scale

Deforestation, Burning fossil fuels (transportation & electricity), Breathing
What happens to the medium after a wave travels through?
It returns to its original position.
