6. Human Impact on the Environment
Acid Rain- form of precipitation that is unusually acidic(low pH). It can have harmful effects on plants, aquatic animals and infrastructure.
The Greenhouse effect- A process in which solar radiation is absorbed by atmospheric greenhouse gases and isn’t able to escape back into space. This causes the atmosphere to increase in temperature over time.
Deforestation- the process where forests are cleared. Plants use sunlight, water and CO2 to produce oxygen, if there are no plants then…..
Ozone Layer- a region of Earth's stratosphere that absorbs most of the Sun's UV radiation. The ozone shield protects us from these harmful rays.

Atmosphere: the layer of gases that surrounds Earth.

15. The Atmosphere
As you view this time-lapse video write down 5 things that occur in the Earth’s atmosphere.

16. Atmospheric Composition
Air is a combination of gases and solid particles.

17. Atmospheric Composition
Earth’s atmosphere consists mainly of nitrogen (78%) and oxygen (21%).
The amounts of nitrogen and oxygen in the atmosphere are fairly constant over time.

18. Atmospheric Composition
But…. the concentrations of some atmospheric gases are not as constant over time…
Any idea of what those gases may be??
Water vapor
Carbon Dioxide

19. Atmospheric Composition
During the past 150 years, the concentration of atmospheric carbon dioxide has increased.
Carbon dioxide traps warm air in our atmosphere and leads to
….Global warming!

20. Atmospheric Composition
Earth’s atmosphere also contains solids in the form of tiny particles, such as dust, salt, and ice.
Very important to the water cycle!!

21. How many atmospheric layers are there?!?!

22. The atmosphere is classified into five different layers:
Atmospheric Layers
The atmosphere is classified into five different layers:
Exosphere

33. Troposphere Tropo= “turning” or “change”
As you increase in altitude, temperature decreases.
As you increase in altitude, pressure decreases.
Facts:
90% of the atmosphere’s total mass.
Weather occurs here.
Gases are constantly mixing.

34. Exosphere Exo – “outside” or “beyond”
As you increase in altitude, temperature decreases.
As you increase in altitude, pressure decreases.
Facts:
The transitional region between Earth’s atmosphere and outer space

46. Demo: Cloud in a Bottle Materials: Plastic Bottle Warm Water Match
Procedures: 1. 2.
Summarize HOW clouds are formed!!!

47. Demo: Cloud in a Bottle
Clouds are formed when water droplets in the air cool and then collect on dust particles.
The dust particles were provided by the smoke from the match.
The air inside the bottle was cooled by releasing the pressure after the bottle was squeezed.
The temperature is changed by squeezing the bottle: the amount of air within the bottle is constant, but squeezing the plastic bottle changes the volume of the gas. Expanding the bottle causes a lowering of the air temperature – in this case, enough to cause the water gas to form a liquid – the cloud.

48. Clouds in the atmosphere are formed the same way!
Cloud Formation
Clouds in the atmosphere are formed the same way!
Clouds are formed when air containing water vapor is cooled and moisture condenses into droplets on microscopic dust particles in the atmosphere. The air is cooled during its upward movement.

49. Types of Clouds
Clouds are generally classified by the altitudes at which they form and by their shapes.

50. Types of Clouds
Low clouds- Mostly composed of water droplets and are found at 6,500 feet.
Middle clouds- Composed of water droplets and sometimes ice. They typically appear between 6,500 and 20,000 feet.
High clouds- Composed of ice crystals. They form above 20,000 feet and at cold temperatures.

52. Precipitation
