Gases
What is the term for gases in the atmosphere that interact with energy radiating from the Earth, that "trap" more energy in the Earth System
Greenhouse Gases
What vocabulary word describes a system that has an equal amount of energy entering and exiting?
Stability
Approximately how many people live on Earth?
about 8 billion
What does Reforestation mean?
Planting trees so that they can gobble up CO2 in the atmosphere and produce Oxygen
What kinds of foods are best to be cut with a serrated blade knife?
Tomatoes, Bread (things that are soft or delicate)
What are the two must abundant greenhouse gases in Earth's atmosphere?
Carbon Dioxide & Methane
When there is an increase in the amount of greenhouse gases in the atmosphere, what will happen to the amount of energy that is exiting the Earth system? (increase, decrease, stay same)
Energy exiting will decrease (more gets trapped in), which will increase temperature.
Which of the following sources of energy produces the least amount of gas emissions?
A fireplace, a coal furnace, a propane heater, a windmill.
Windmill. Others produce gases by combustion
Solar Panels and Wind Turbines are renewable energy sources that do not put greenhouse gases into the atmosphere. Because wind is the result of rising and sinking air all over the world, wind turbines can be installed at any latitude. Solar panels however, work much better at certain locations than others. Where on Earth is an ideal location to install solar panels?
Equatorial Regions (most direct sunlight)
These are usually made of metal, and are used to pick up hot items by pinching them. They make a fun clicky clacky noise
Tongs
What types of human activities put Carbon Dioxide into the atmosphere?
Combustion (burning) fossil fuels in engines, factories, power plants, etc.
With the recent trend of increasing global temperatures, is there more energy entering or exiting the Earth system?
Entering. Less is exiting because greenhouse gases trap energy in the atmosphere.
Solar panels are a power alternative that does not put gas emissions into the atmosphere, but they aren't practical to use everywhere. Why might solar panels not be as effective near Earth's poles?
The polar regions do not receive much direct sunlight. Locations near the equator and mid latitudes would be more suitable for solar energy.
What are 3 things that can be done to reduce greenhouse gas emissions in the atmosphere? Can be personal or large-scale ideas/solutions.
Drive Less, Carpool, Eat less meat, use renewable resources, plant more trees, carbon capture.
This is a large bowl with many many holes in it that is used to drain water, without spilling large ingredients.
Colander
Which 3 of these gases are NOT greenhouse gases?
Carbon Dioxide, Oxygen, Nitrogen Dioxide, Methane, Water Vapor, Sulfur Dioxide.
Oxygen, Nitrogen Dioxide, and Sulfur Dioxide are NOT greenhouse gases
Some of Earth's surfaces are covered in ice and snow. These surfaces are reflective and don't absorb much solar energy. As the Earth gets warmer, what will likely happen to the amount of reflective cover on earth, and what will happen to Earth's temperature?
Snow and ice melt, so reflective cover decreases, which would increase Earth's temperature
Describe to me how an increasing human population leads to glaciers melting rapidly?
Up to Wehrle
more people > more gas emissions > more greenhouse gases trapping energy > temp goes up > ice melts.
If the cows diets makes them fart and poo less, or if they produce less methane, there will be less methane in the atmosphere, which would allow more energy to exit Earth's atmosphere.
This large, square shaped kitchen knife is mostly used for hard things like bones and tough meats, but can also be used to finely chop and even crush some ingredients.
Cleaver
Explain to me why greenhouse gases only interact with energy that is exiting earth, and not the energy coming in from the sun?
The energy coming in is traveling on a faster wavelength. It slows down when it hits the earth, and the gas molecules are vibrating at a speed that matches the slower energy wave, causing interaction with the gas (energy will bounce off)
During the Cryogenian Period of Earth's history, there was a decrease in Carbon Dioxide in Earth's atmosphere, which ultimately caused a "snowball earth". What are two Reasons that the Earth became covered in snow and ice at this time?
1. Less carbon dioxide allowed more energy to escape, cooling down the earth. 2. The reflective snow and ice allowed more energy to be redirected back into space
Describe to me why an increase in human population could lead to Coastal communities being flooded by ocean water.
Up to Wehrle
What is the name of the process where factories can collect their gas emissions, and store them somewhere else, which keeps them out of the atmosphere?
Carbon Capture
This metal utensil has a handle and a surface with many small sharp holes, like a cheese grater but even smaller, and is used to finally grate things like cheeses and fruit skin.
