Q

What is anthropogenic?

A

Man made

17
Q

What are examples of Anthropogenic

A

Cars
Facories
Deforestation
Fossil fuel usage

18
Q

What keeps us warm?

A

The GreenHouse Effect

19
Q

What is the GreenHouse Effect?

A

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

20
Q

GreenHouse Effect Steps

A
  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
21
Q

What greenhouse gas is the most abundant?

A

Water vapor

22
Q

GreenHouse Gas equation

A

New - Old over Old times a 100

23
Q

What happens when sea ice and glaciers melt?

A

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

24
Q

What is the difference between ice caps and sea ice?

A

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

25
Q

What is thermal expansion?

A

As something gets hotter, it takes up more volume

26
Q

What are your greenhouse gases?

A

Carbon Dioxide
Water Vapor
Nitrous oxide
Ozone
Methane

27
Q

What is GWP?

A

Global Warming Potential

28
Q

What gas has the greatest Global Warming Potential?

A

Flour instead Gases
(HFC’s)

29
Q

What is Albedo?

A

Amount of ice reflectivity coming back
