1. Unit 3 Study Guide outline honors science

2. What is the difference between renewable and nonrenewable resources?
Renewable Resource - Natural resources that can be replaced by nature at a rate close to the rate at which they are used.
Nonrenewable Resource - A natural resource that exists in a fixed amount.
They are renewed very slowly or not at all.
Consumption is faster than the rate it can be replaced.

3. Make a t-chart of renewable vs. nonrenewable resources.
Solar
Wind
Water
Geothermal
Biomass
Coal
Oil
Natural Gas
Petroleum
Uranium (nuclear)

4. Identify activities that increase:
The amount of Carbon Dioxide in the atmosphere
Burning fossil fuels due to transportation and using electricity.
Respiration
Deforestation
Volcanoes erupting
The amount of Methane in the atmosphere
Landfills
Animal Waste
The amount of Water Vapor in the atmosphere
Increasing temperatures cause more evaporation which increases the water vapor in the atmosphere

5. Provide details for each of the following natural hazards
Provide details for each of the following natural hazards. Include information like the tools used to predict them, the scales use to measure their intensity & their locations.
Earthquake
Seismograph – records the motion of the ground caused by an earthquake, but does not predict when they will occur.
The Richter Scale measures the intensity of the earthquake
They occur mainly around the Ring of Fire due to the many plate boundaries
Hurricane
Radar is used to track the direction of the hurricane so we can predict when they will hit certain locations
The Saffir Simposn Hurricane Scale measures the intensity of the hurricane
When they hit the United States it is on the East Coast because they start in the Atlantic Ocean and move westward.
Tornado
Doppler radar is used to predict it will occur but cannot pinpoint the exact location.
The Enhanced Fujita Scale categorizes the hazard by wind speed
They mostly occur in tornado alley in the Midwest of the US due to the flat lands.

6. What is climate change?
a long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature

7. What happens to the environment due to the climate changing?
Polar ice caps are melting which causes sea level to rise (increase in flooding)
More severe natural hazards. For example, a warmer climate increases water temperature which will increase the severity of hurricanes

8. Explain (in detail) what has happened to human population from 0 AD to today.
From 0AD to the 1700’s there was a steady, slow increase in human population.
The Industrial Revolution took place in the 1700s which gave us an advancement in machinery, technology and medicine. This is when we started seeing a vast increase in human population.

9. Draw and label the steps involved in the greenhouse effect.
1. The sun radiates heat to Earth
3. The Earth radiates the rest of the heat back toward space
2. The Earth (land and water) absorbs about 51% of the heat
4. Greenhouse gases in the atmosphere trap about 19% of the heat in our atmosphere.

10. Two plastic bottles: _________ Alka-Seltzer tablet: _________
Recall the Greenhouse Effect Lab that we did in class. Explain what the materials represented. What happened to the temperature in each bottle? Why?
Two plastic bottles: _________
Alka-Seltzer tablet: _________
Water: _________
Sealed bottle: _________
Heater: _________
Earth’s surface
CO2 Emissions (greenhouse gas)
Earth’s surface/water vapor (greenhouse gas)
Atmosphere
Sun
The temperature in both of the bottles increased. The bottle with one greenhouse gas (the water vapor only) did not increase as much as the other bottle that had two greenhouse gases (carbon dioxide and water vapor)
