8.4.4-With the concerns about global warming increasing, the production of gases and their effects on the atmosphere are being closely watched. When fossil fuel is burned in a car engine, ________ increases in the atmosphere.
Hydrogen
Oxygen
Carbon Dioxide
Nitrogen
8.4.4-Choose all of the examples of Climate
Utah is a desert.
Is it snowing in Salt Lake City today.
The Bahamas are typically hot and sunny, with moderate rainfall.
The average temperature of the Northwest has increased by 1 degree Fahrenheit over 30 years.
Florida is going to have a windstorm, maybe even a hurricane!
8.4.4-When the combustion engine was invented it had many positive effects on society, but years later it has been discovered that the burning of oil and coal has one major negative effect on the environment. What is that negative effect?
It improves air quality
It increases the greenhouse effect
It uses renewable resources
It only causes a hole in the ozone
8.4.4-Analyze the relationship between CO2 emissions and surface temperature change between 1950 and 2000 using the data presented in the graphs.
increase emissions leads to an increase of CO2 in the atmosphere which may be the cause of the increase in temperature
increase emissions leads to an increase of CO2 in the atmosphere which may be the cause for the decrease in temperature
increase emissions leads to a decrease of CO2 in the atmosphere which may be the cause of the increase in temperature
increase emissions leads to an increase of CO2 in the atmosphere which definitely causes the increase in temperature
8.4.4-Which of these energy sources have the cleanest output?
Petroleum and Nuclear
Solar and Wind
Solar and Nuclear
Coal and Petroleum
8.4.4-Sustainable use is often defined as the use of natural resources at a rate that meets the needs of the present human population but which also allows future generations to use the resource to meet their needs. Which of these BEST illustrates the concept of sustainable use?
Crops are rotated in a farmer's field to maximize grain yields
A fishing trawler uses a large net to catch a school of small fish
A logging company reseeds and replants in a forested area after cutting down trees for timber
Coal is mined using underground tunnels to avoid destruction of surface soils by strip mining.
8.4.4-During the past 40 years, close to 20 percent of the Amazon rain forest has been cut down, more than in all the previous 450 years since European colonization began. Scientists predict that an additional 20 percent of the trees will be lost over the next 20 years. The Amazon rainforest, like other rainforests, produces half its own rainfall through the moisture it releases into the atmosphere through transpiration. Eliminate enough of that rain through deforestation, and the remaining trees dry out and die. Other problems result from the deforestation of rainforests. One can be seen here.
Deforestation leads to many negative situations on Earth as illustrated by this satellite image. All BUT ONE is a consequence of the deforestation of the rainforest. That is:
Deforestation leads to extinction of species
Deforestation leads to bare soil that is easily eroded
Deforestation leads to the destruction of many wildlife habitats
Deforestation leads to a decrease in fossils fuels
The burning of fossil fuels barely contributes to global warming.
True
False
8.4.4-The burning of fossil fuels barely contributes to global warming.
Tips to Conserve Energy
Ways to Reduce Pollution
Ways to Help the Environment
Tips to Conserve Water
8.4.4-The graph indicates what about the relationship between atmospheric carbon dioxide and time
over time, the amount of atmospheric carbon dioxide decreases
over time, the amount of atmospheric carbon dioxide stays the same
over time, the amount of atmospheric carbon dioxide increases
over time, the amount of atmospheric carbon dioxide does not change
8.4.5-Which natural hazard often presents warning signs before it occurs?
Tsunamis
Earthquakes
Landslides
Volcanic eruptions
8.4.5-Why do scientists collect data from natural hazards?
To develop technologies to mitigate effects
For scientific records only
To understand animal behavior
To predict the weather
8.4.5-What can the study of patterns in natural hazards help us predict?
Likelihood of future catastrophic events
Rainfall amounts in different locations
The exact time an event will occur
The speed of tornado winds
8.4.5-Why is earthquake predicting not as reliable as predicting other hazards?
Scientists don't study earthquakes
Earthquakes only happen in specific regions
Earthquakes can occur without warning
Earthquake data is often lost
8.4.5-How can the prediction of natural hazards help mitigate their effects?
Stop the occurrence
Decrease its intensity
Preparation and planning
Minimize the hazard
