100
How are natural resources distributed?
They are distributed unevenly throughout the Earth.
100
What type of resource is a fossil fuel?
Non-Renewable resources.
100
What do greenhouse gases do to the Earth?
They absorb and trap heat like a blanket, which raises Earth's average temperature.
100
True or False
Earth has a pattern of extreme climate changes throughout its history
True
100
Define a renewable resource, and give an example.
Any natural material that does not run out or can be replenished.
Sunlight Wind Water Trees
Soil/organic material (biomass)
200
Which country has the biggest reserve of oil?
Venezuela
200
What are two types of fossil fuels?
Oil, natural gas, and coal.
200
With an increase of population, what happens to the use of fossil fuels, and therefore greenhouse gases?
Increase
200
How do warming temperatures affect sea levels?
Water expands when heated, and glaciers/ice melt, sea level rises
200
What is the difference between a natural resource and a synthetic resource?
A natural resource is a material that comes from nature.
A synthetic resource is made by humans from natural materials.
Example oil is natural - plastic bottles are synthetic.
300
Name some resources that are unevenly distributed.
oil, copper, water, coal, timber, etc.
300
What happens when fossil fuels are processed/burned?
It adds CO2, a greenhouse gas, to the atmosphere.
300
Name a natural source of greenhouse gases.
Natural forest fires
volcanic activity
Cellular Respiration
Decomposing organic material
Ocean exchanging gases with the atmosphere
300
Definition of Climate Change?
A change in global climate patterns.
300
How much of Earth's water resource is fresh water?
3%
400
How were natural resources created/distributed?
Created by geologic processes like tectonic plates, volcanoes, earthquakes, erosion, weathering, mountain uplift, etc.
400
Where do oil and natural gas come from? Remember what they are called...
The remains of organisms.
400
What would the Earth be like without the greenhouse effect?
It would be cold.
400
How does cutting down trees affect climate change?
Fewer trees, less storage of CO2, more greenhouse gases, and more trapped heat.
400
What happens to natural resources when the population increases?
Demand increases, so they are less available and more expensive.
500
What are three ways countries deal with the uneven distribution of resources?
Buy/Trade
Develop manufacturing/technology/workforce
War/conflict
500
Which fossil fuels are usually found in the same area?
Oil and natural gas.
500
Name two greenhouse gases.
Water vapor - H2O
Carbon Dioxide CO2
Methane CH4
500
What does climate change do to the weather hazards like severe storms and droughts?
Makes the weather more severe, and weather hazards happen more often.
