What are greenhouse gases? (definition)
Gases such as carbon dioxide and methane that absorb radiation from the sun and trap the heat in the atmosphere.
What is Global Warming?
A gradual increase in temperature of the Earth's atmosphere caused by gases and pollutants.
What is Climate Change?
A change in a region's weather conditions, over a long period of time.
What are fossil fuels?
Natural fuel formed from the remains of living organisms.
What is Global Climate?
The range of weather that varies from region to region?
What are three greenhouse gases we talked about?
- Water Vapor
- Carbon Dioxide
- Methane
What impact does agriculture have on the humans and the environment?
It is an industry that supplies us with food. Greenhouse gases are emitted from cows belching (methane) and from fertilizer (nitrous oxide).
What is deforestation and what impact does it have on the environment?
When trees are cut down, leading to less trees absorbing the carbon dioxide.
When there are less organisms like kelp and trees, what happens to the CO2 levels in the atmosphere?
There is MORE CO2 in the atmosphere.
What event in the world lead to the increase of greenhouse gases in the atmosphere?
The industrial revolution.
What are three examples of fossil fuels?
- oil
- natural gases
- coal
- petroleum
What is examples of renewable resource?
- Solar energy
- Wind power
What is ocean acidification?
The acidity of the ocean increasing due to an increase in CO2 levels.
Since the 1800s what have we seen changed with global temperatures?
They have increased in record high temperatures.
What has happened to the ice caps in the last 100 years, and why?
They have melted leading to an increase in the sea levels. This is because of the rise in global temperatures.
How do fossil fuels form?
They form over the millions of years from the remains of the fossils of dead animals and plants that have been buried under the ground. Heat from the earth's core and pressure from the ground above lead to fossils changing into different fossil fuels.
Why is it better to use renewable resources over nonrenewable resources?
Renewable resources lead to lower levels of greenhouse gases.
Why is transportation the leading cause of emitting greenhouse gases?
Every car, plane, and other forms of transportation release CO2 in the atmosphere.
What are 4 natural processes that contribute to greenhouse gases in the atmosphere?
- Respiration
- Decomposition
- Volcanoes
- Solar Radiation Changes
What is one way humans can help the save the environment?
- Reduce, Reuse, Recycle
- Decrease the amount of pollution we release.
- Use renewable resources
