What is a general description of Wind turbines?
Wind turns a turbine that is connected to a shift within a generator which will in turn produce electricity
What are the 2 main advantages and disadvantages of using wind turbines?
Advantages -clean renewable energy -land around the wind turbines can be used for grazing Disadvantages -kills many birds and bats flying through the area -high initial cost
What are the 2 main advantages and disadvantages of using HydroPower- Dam?
Advantages -often producers reservoirs -can prevent flooding Disadvantages -can cause flooding restricts migrating fish from passing through -sediments can pass through or get jammed
What are the 2 main advantages and disadvantages of using Geothermal?
Advantages -does not produce greenhouse gases emissions -inexhaustible supply Disadvantages -scarcity of geothermal sites -local climate destruction
What are the 2 main advantages and disadvantages of using wind turbines?
Advantages -moderate to high energy yield -no greenhouse gases emissions Disadvantages -expensive -can only be used in the day
What are four examples of renewable sources
Solar, Hydropower, Wind turbines, Geothermal
What are the three main greenhouse gasses?
CO2 Methane N20
What is a natural and man-made source for CO2?
Natural source- Volcanic eruptions, respiration Man-made source- burning fossil fuels
What is a natural and man-made source for Methane?
Natural source- wetlands Man-made source-livestock, landfills
What do greenhouse gases do in our atmosphere?
They absorb radiation that passes through the troposphere
What is a natural source of greenhouse gases?
denitrification
Which gases have the greatest impact on climate change?
methane; carbon dioxide
Concentration levels of which greenhouse gas is most affected by human activity of burning fossil fuels?
carbon dioxide
What is a greenhouse gas emitted from natural anaerobic processes typically associated with saturated soil conditions, such as in a swamp?
Methane
Habitat destruction and deforestation can cause
an increase in CO2 in the atmosphere
Which is a negative consequence of ocean acidification?
a decline in the production of shelled organisms
What is albedo?
a measure of how much light hits and is reflected off a surface
What does climate change do to sea turtle populations?
creates more females
