Unit 6-1
What is the definition of atmosphere?
A mixture of gas that surrounds the Earth.
What is the carbon cycle?
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms on the Earth and then back into the atmosphere over and over again.
What is Climate Change?
Earth’s climate changing effectively because of the greenhouse effect.
How to reduce greenhouse gas emissions from transportation?
Drive less and fly less.
What is atmospheric pressure?
Pressure by the weight of the Earth’s atmosphere at any point on Earth.
What are respiration and combustion?
Respiration: Transfer of energy from food in plants and animals.
Combustion: Fuel such as wood, petrol, and methane produce Co2 on burying.
What is Global Warming?
Earth’s temperature changing over a long period of time because of the amount of greenhouse gases and the sunlight temperatures.
How to reduce greenhouse gas emissions from shopping products?
Use reusable bags.
What is global warming?
Gradual increase in the air temperature at the surface of the Earth.
What are 2 processes to remove carbon dioxide from the atmosphere?
1. Photosynthesis.
2. Dissolving in the ocean.
Give examples of carbon footprint.
Burning gasoline when we drive, burning oil or gas for home heating, or using electricity generated from coal, natural gas, and oil.
How to reduce greenhouse gas emissions from Home life?
Reduce the amount of electricity used in the house (ex. Heater, Light).
What is the greenhouse effect?
The transfer of energy(heat) from the Sun to the thermal energy store of gasses in the Earth’s atmosphere
Tell 3 things that carbon sinks include.
Ocean
Soil
Areas of vegetation
Give all of the greenhouse gases.
Carbon dioxide, methane, nitrous oxide, hydrochlorofluorocarbons, hydrofluorocarbons, and ozone.
What is Carbon Footprint?
Carbon footprint is the total amount of greenhouse gas emissions that come from production.
What are the 5 stages of the nitrogen cycle? (in order)
Nitrogen fixation, nitrification, assimilation, ammonification, and denitrification.
How does carbon get back into the atmosphere from the food we eat?
Respiration
Execration
Decomposition
What are the similarities and differences between Climate Change and Global Warming?
Both are caused by the amount of greenhouse gasses and they make creatures difficult to survive, but climate change is Earth’s climate changing, and global warming is Earth’s temperature increasing.
Advantages and Disadvantages of Carbon tax (2 or more).
Advantages
Added cost can reduce emissions by motivating consumers to seek cleaner energy
Boosts economic growth by substantially increasing government revenue
Funds agencies managing climate change effect
Disadvantages
A carbon tax is regressive
A sudden increase in a carbon tax would shock the economy
It penalizes those who can’t switch to alternatives
