Renewable and Nonrenewable Energy
What is a fossil fuel?
The trapping of the sun’s heat in the atmosphere due to greenhouse gasses. This ultimately warms the earth beyond what it needs.
Greenhouse Effect
The melting of glacial ice due to climate change. This causes more of the sun’s rays to be absorbed by darker colored surfaces.
Albedo Effect
What have humans done to cause negative impacts upon salmon numbers?
Anything discussed in class...
The long-term changes in global temperatures and alterations in other aspects of the climate.
Climate Change
A type of renewable energy that uses the sun.
Solar energy
A type of greenhouse gas.
carbon dioxide, methane, water vapor, CFCs, etc (any from notes or discussed in class)
What happens to atmospheric and land temperatures when more ice melts.
It increases
The removal of trees, or _________ is a contributing factor to climate change due to humans.
deforestation
What acid is created when more carbon dioxide is added to our oceans?
A type of energy that uses large winndmills.
Wind power
This greenhouse gas causes the pH of the ocean to decrease because it creates carbonic acid in the waters on Earth.
Carbon dioxide
A large mass of ice on the surface of the land.
Glacier
The burning of _____________ _____________ from dead organisms is a major contributing factor to climate change.
The pH number all living things, including salmon, prefer to sustain life.
Neutral, pH 7
Nonrenewable energy forms (3)
Coal, Oil and Gas
This greenhouse gas comes from all the cattle we rely on to feed us beef when they fart, as well as the decomposition of organic matter, and burning of fossil fuels.
Methane
How does the Albedo Effect contribute to salmon decline?
It increases air temperature, increasing sea temperature, decreasing salmon population.
What anthropogenic factors are causing the change in pH within the oceans and waters that salmon live in?
A low pH is considered to be which of the following?
acidic, basic, alkaline, turbid
Acidic
Hydroelectric Power
Carbon dioxide
What causes the Albedo Effect to be accelerated?
More greenhouse gasses in the atmosphere, less reflection of the sun's rays into the upper atmosphere, more glacial ice melting (any other logical explanation.)
These gasses trap heat in the atmosphere and are due to humans burning fossil fuels.
greenhouse gasses
Which of the following is considered an acid?
H+ OH - H2CO3 HCO3-
H+ H2CO3
