The Atmosphere

By: Cayla Hashe and Lauren Rush

Greenhouse Gasses in the Atmosphere

Greenhouse gasses trap heat inside of the atmosphere.


Examples:

1. Ozone: Comes from the breakdown of oxygen molecules by UV rays.

2. Carbon Dioxide: Comes from the exhale of humans and animals.

3. Methane: Comes from decay of organic materials

Positive and Negative Effects

Positives:

1. Keeps the Earth warm

2. Keeps plants alive


Negatives:

1. Melting polar ice caps

2. Leads to global warming

carbon dioxide and ozone effects

Increased Carbon Dioxide:
  • Harder to breathe
  • Warmer temperature
Decreased Carbon Dioxide:
  • Easier to breathe
  • Less trees
  • Colder temperature

Increased Ozone:

  • Less heat
  • Darker sky
  • More protection from sun's UV rays
Decreased Ozone:
  • More heat
  • Less harmful UV rays

Increased Oxygen:

  • People would be more athletic (taller, bigger, stronger)
  • Easier to breathe
Decreased Oxygen:
  • Harder to breathe
  • Fires would be less strong


Global Warming

Global Warming: a gradual increase in the overall temperature of the earth's atmosphere

Causes:

  • Pollution is deteriorating the ozone layer
  • Increased population is requiring more transportation and more power/heat which leads to the burning of fossil fuels (coal etc.
Opinion:

  • We think that this is a serious issue in the world and a legitimate concern. It is important to be aware of the issue because affects our environment in many negative ways. We can try to stop this by doing our part such as working to decrease pollution.


endangered species

Penguin:


Since sea ice is melting very fast, arctic animals such as penguins have nowhere to live. Their home is disappearing and they don't have anywhere else to go that they are able to survive in. This has lead to the death of tons of species such as the penguin and other arctic animals. Penguins that live in the ocean open however, are okay since they do not depend on the ice for their habitat.
