Question 2

What are Externalities?

Answer 2

Implications that are not accounted for in the price(Unintended side effects)

Question 3

Answer 3

Living on Earth in a way that allows humans to use its resources without depriving future generations of those resources

Question 4

What are the layers of the Atmosphere?

Answer 4

Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere

Question 5

What gases make up the atmosphere?

Answer 5

78% Nitrogen
21% Oxygen
1% Other gases

Question 6

What is the Troposphere?

Answer 6

Ground-Level
“Bad Ozone” = Pollution
Cold = Temperature decreases
Holds majority of atmospheric molecules

Question 7

What is the Stratosphere?

Answer 7

Planes
Hot = Temperature and Altitude increase
Good Ozone = Protects against UV

Question 8

What is the Mesosphere?

Answer 8

Middle
Coldest Layer = Temperature decreases
Meteors burn up

Question 9

What is the Thermosphere?

Answer 9

Hottest layer = Temperature increases
Northern Lights

Question 10

What is the exosphere?

Answer 10

Satellites orbit
Outermost layer

Question 14

Kyoto Protocol

Answer 14

Japan
Reduces greenhouse gas emissions
CO2 NO2
CH4 (Methane)

Question 15

Paris Agreement

Answer 15

Long term temperature goal to keep global temperature below 2 degrees Celsius

Question 16

What is anthropogenic?

Answer 16

Man made

Question 17

What are examples of Anthropogenic

Answer 17

Cars
Facories
Deforestation
Fossil fuel usage

Question 18

What keeps us warm?

Answer 18

The GreenHouse Effect

Question 19

What is the GreenHouse Effect?

Answer 19

Infrared radiation hits the greenhouse molecules causing them to vibrate and warm the air

Question 20

GreenHouse Effect Steps

Answer 20

1. Solar radiation passed through the atmosphere and warms the Earth’s atmosphere
2. The energy is absorbed by Earth’s surface and radiated as infrared
3. GreenHouse gases absorb most of this energy

Question 21

What greenhouse gas is the most abundant?

Answer 21

Water vapor

Question 22

GreenHouse Gas equation

Answer 22

New - Old over Old times a 100

Question 23

What happens when sea ice and glaciers melt?

Answer 23

Less dense water in polar regions which decreased the sinking of colder water and slows down ocean currents

Question 24

What is the difference between ice caps and sea ice?

Answer 24

Ice cap is on land
Sea ice is on water(ocean)

Question 25

What is thermal expansion?

Answer 25

As something gets hotter, it takes up more volume

Question 26

What are your greenhouse gases?

Answer 26

Carbon Dioxide Water Vapor Nitrous oxide Ozone Methane

Question 27

What is GWP?

Answer 27

Global Warming Potential
