HUMAN IMPACT PROJECT

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.

The Atmosphere

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

http://www.youtube.com/watch?v=O3L6p1zDs6k

Air is a combination of gases and solid particles.

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.

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

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!

Atmospheric Composition

Earth’s atmosphere also contains solids in the form of tiny particles, such as dust, salt, and

ice.

How many atmospheric layers

are there?!?!

Atmospheric LayersThe atmosphere is classified into five different layers:

ExosphereThermosphere

MesosphereStratosphere Troposphere

Ionosphere

How do we know this??

Layers of the Atmosphere

Each layer is defined by:

•Composition of gases

•Air Pressure

•Temperature

Thermosphere

• Thermo– “heat”

• As you increase in altitude, temperature increases.

• As you increase in altitude, pressure decreases.

• Facts:

• Atoms of N and O absorb high-energy solar radiation and release thermal energy.

• 1,000 degrees C or higher But… it does not feel hot!

• (temp is different from heat)

• Charged particles cause shimmering lights called auroras!

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

• Most satellites orbit in this layer.

Why does the temperature fluctuate depending on the layer??

Summarize HOW clouds are formed!!!

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.

Cloud Formation

• 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.

Clouds in the atmosphere are formed the same way!

Types of Clouds

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

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.

Cloud ShapesLatin Root Meaning

Precipitation

Water moves from Earth to the atmosphere and back to Earth in the water cycle.

Precipitation

All forms of water that fall from clouds to the ground are precipitation.

Rain, snow, sleet, and hail are the main types of precipitation.
