A material that can be replaced faster than it is used. Give an example.
Renewable Resources
ex: water, wind, solar energy, etc.
The process of digging into Earth's surface to remove resources.
Mining
Fuel formed from ancient plants and animals.
Fossil Fuels
A chart dividing Earth's history into different time periods.
Geologic Time Scale
Technology used to gather information about an object without directly observing it.
Remote Sensing
A material that cannot be replaced as fast as it is used. Give an example.
Nonrenewable Resources.
ex: coal, oil, natural gas, copper, etc.
Areas containing significant amounts of a resource.
Deposits
Are fossil fuels renewable or nonrenewable? Why?
Nonrenewable because they cannot be replenished as quickly as we use them.
Approximately how old is Earth?
4.6 billion years
What is the hardest mineral on the Mohs Hardness Scale?
Diamond
Materials found naturally on Earth and used by people.
Natural Resources
A mining method used when resources are close to Earth's surface.
Open pit mining
What two things help turn dead organisms into fossil fuels over geologica time?
Heat and pressure
What do scientists use fossils and rock layers to determine?
Relative age
A naturally occurring inorganic solid with a crystal structure.
Mineral
As population increases, what generally happens to nonrenewable resources?
They are used up/decrease faster
A rock containing valuable concentrations of minerals.
Ore
Name one example of a fossil fuel.
Coal, oil, natural gas
Geologic time periods are often divided by what major events?
Mass extinctions/major changes in life on Earth
A diagram showing layers of rock viewed from a cliff or drill core.
Stratigraphic Column
Why are resources not evenly distributed around Earth?
Different geological processes formed resources in different locations.
The sinking or compaction of land caused by groundwater removal
Subsidence
Where are fossil fuels formed? How does that related to why scientists don't expect new fossil fuels to form fast enough?
They are formed on the ancient sea floor. Formation takes millions of years, while humans use them much faster.
Which is the oldest layer? Why?
Layer F because of the law of superposition and the cross-cutting law.
