02a The atmosphere

Introduction to Our Atmosphere

ORIGIN OF THE ATMOSPHERE

At first, Earth had no atmosphere.

Then volcanoes released toxic gases like carbon dioxide, water vapor, and nitrogen.
Later, as the planet cooled down and oceans appeared, plants produced oxygen through photosynthesis. This created the atmosphere we have today.

Air is a mixture of gases. It has about

78% nitrogen (N2), (used by some bacteria)

21% oxygen (O2) (used for respiration)

and 1% other gases like

carbon dioxide (used for photosynthesis)

argon, ozone and water vapor.

FUNCTIONS OF THE ATMOSPHERE

GAS RESERVEs: It provides

Oxygen (for respiration)

CO2 (fro photosynthesis)

Nitrogen (essential for life, some bacteria use it)

PROTECTION . meteorite, X rays, Gamma rays, UV rays

TEMPERATURE regulation: Greenhouse effect (gases. CO2, water, methane)

+ METEOROLOGICAL PHENOMENA

Video QUESTIONS

What is the ATMOSPHERE?

The atmosphere is the layer of gases that surround the Earth.

Why do we need Oxygen?

We need oxygen to breath.

What does the mitochondria obtain thaks to the Oxygen?

It gets energy.

What is the AIR mainly made of?

The air is 78% Nitrogen and 21% Oxygen.

Other that N and O, what other gases are in the AIR?

Argon, Methane, Ozone, Carbon dioxide.

Name the 3 main greenhouse gases?

Water vapour, carbon dioxide and Methane.

Write solutions proposed in the video for the Global Warming issue.
Use less the car/ Go walking or by bicycle./ Plant trees and avoid deforestation./ Reduce, Reuse and Recycle.
Draw the molecule of Ozone:

O-O-O

Which gases destroy the ozone layer and where do they come from?
CFC gases from refrigerators and sprays
What is the title of this video?

We are what we breathe. If you take care of the aire you take care of yourself.

Atmosphehere and Geosphere CARDS GAME - DIY the Game!

Obtained from https://deceptivelyeducational.blogspot.com/2015/10/earths-layers-atmosphere-card-game-free.html

This is a set of 1-10 playing cards plus wild cards, for us to play like Skip-Bo Junior.

Download a free 11-page PDF of the playing cards from Google Drive here.

Print on heavyweight cardstock and cut out. Print two copies of the WILD cards (on page 5). NOTE: This is a pretty ink-heavy printable; I recommend taking the PDF to a copy shop so as not to use up all your home printer's ink.
