Module 10 Earth Science
Approximately what percentage of plastics are actually recyclable?
10
What percentage of the Earth is water?
71%
The United State's EPA regulates more than _____ different toxins that can be found in industrial pollution.
80
Burning coal, oil, and natural gas has led to an increase of this in the atmosphere
C02
What is a major factor in building up the heat in the Earth's atmosphere?
C02
What are the three gases in our atmosphere that make life on Earth possible?
Carbon dioxide, methane, and nitrous oxide
What are the two main types of pollution flooding the ocean?
Chemicals and trash
How do chemicals make their way into aquifers? Please answer using complete sentences.
Chemicals can make their way into aquifers when farmers use pesticides and fertilizers on their fields and it sinks into the water table and then into the wells. It can also get into aquifers when pesticides, fertilizers, and hazardous wastes are used, they can runoff into the ground and into aquifers.
Which of the following is an example of recycling?
Collecting and using materials to make something new
What brings warmer than normal surface ocean temperatures in the tropics?
El Niño
What is NOT a cause of land pollution?
Emissions
Describe what happens in an El Niño event? Please answer using complete sentences.
In an El Niño event the surface temperature of water in the tropics increases and the Winds in the equator weaken and reverse. The global pattern of the wind in weather is changed and can effect animals, drought, winters, hurricanes and other types of weather making everything more warm.
What happens to plastic waste?
It often ends up in the ocean for fish to eat.
Radon
Just about all soil has some trace amounts of uranium in it. When uranium undergoes radioactive decay, it releases radioactive radon gas. This is a natural source of pollution that eventually winds up in all groundwater.
What are well-engineered and managed facilities for the disposal of solid waste?
Landfills
Chemicals
Man-made and naturally occurring chemicals can make their way into aquifers. Farmers use pesticides and fertilizers on their fields that can make their way into the water table and then to wells.
Periodic cycles in the Earth's orbit around the Sun
Milankovitch Cycles
What are the periodic cycles in the Earth's orbit around the Sun?
Milankovitch Cycles
What causes trash islands to form?
Ocean currents
Salt
One way to remove ice and snow from the roads is to treat the roads with rock salt. When the snow and ice melt, it can carry with it sodium chloride, which dissolves in water. When salt enters the groundwater system, it pollutes it making it unusable.
What are the benefits of recycling? Please answer using complete sentences.
Recycling helps reduce the quantities of solid waste deposited in landfills and it reduces the pollution of air, water, and land resulting from waste disposal.
What is an example of long-term health effects of air pollution?
Respiratory disease
What is the sinking of land in areas where excessive amounts of water were removed?
Subsidence
How does soil become contaminated?
The incorporation of unwanted chemicals in the soil due to human activity
What is a way to reduce plastic waste?
Using reusable shopping bags
What were widespread following Noah's flood which set the stage for the Ice Age?
Volcanic eruptions
What are the effects of land pollution?
What are the effects of land pollution?
Caused by smoke and emissons generated by burning fossil fuels
air pollution
Which of the following is a way to improve the overall air quality?
carpooling
What items are used in a landfill to protect against pollution?
clay flexible plastic soil
Warmer than normal surface ocean temperatures in the tropics
el nino
Chemical contamination
factory discharge fertilizers waste runoff rom septic tanks water treatment discharge oil spills
Which of the following is NOT recyclable?
food
Ensuring availability of water for future generations is a __________.
goal of water conservation
What provides direct information about how temperatures and greenhouse gas concentrations have changed in the past?
ice cores
Cooler than normal ocean temperatures may occur in the tropics
la nina
What is the most common form of soil contamination?
lead
marine trash
plastic bottle caps food wrappers cigarette butts old fishing nets
What is a natural source of pollution that eventually ends up in all groundwater?
radon
_____ pollutants are those harmful substances that are created from the reactions between primary pollutants and the components of the atmosphere.
secondary
These do have an effect on how much energy hits the planet
sunspots
This type of aquifer is more vulnerable to pollution
unconfied aquifers
This combined with warm ocean temp. set the stage for the ice age that followed Noahs flod
volcanic activity
Caused by toxins contaminating the local water supply
water pollution
