The AtmosphereAs you view this time-lapse video write down 3 things that occur in the Earth’s atmosphere.

Atmosphere: the layer of gases that surrounds Earth.

The Atmosphere

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.


The concentrations of some atmospheric gases are not as constant over time as the concentrations of N and O.

• Water vapor • Carbon Dioxide


• 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!


What about the Ozone layer??

The ozone layer blocks harmful ultraviolet rays from reaching Earth’s surface.

Molecules of ozone are formed by the addition of an oxygen atom to an oxygen molecule.

O3


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

ice.


Very

important

to the

water

cycle!!

Atmospheric Layers

The atmosphere is classified into five different layers: TroposphereStratosphere Mesosphere

Thermosphere Exosphere

Inosphere

1.Write down one amazing fact about:

• Troposphere-• Stratosphere-• Mesosphere-• Thermosphere-

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.

Stratosphere• Strato– “layers”

• As you increase in altitude, temperature increases.


• Facts:

• Gases are layered and don’t mix

• Ozone layer

• Air is thin and contains very little moisture.

Mesosphere• Meso– “middle”



• Facts:

• Middle layer

• Coldest layer (-93 degrees C)

Thermosphere• Thermo– “heat”

• As you increase in altitude, temperature increases.


• 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”



• Facts:

• The transitional region between Earth’s atmosphere and outer space

• Most satellites orbit in this layer.

You are lying in a park. Your eyes are closed, and you feel the warmth of the sun on your face….

•Have you ever stopped to think that it takes a little more than 8 minutes for the energy that warms your face to travel from a star that is 149,000,000 km away?!

Where do we get our energy??

Yes…. The SUN!

How is energy transferred (moved) in the atmosphere??

•Radiation•Convection•Conduction

Energy Transfer in the Atmosphere

The Earth receives energy from the sun by radiation.

Radiation is the transfer energy as electromagnetic waves.


Only 2 billionths of the sun’s energy makes it to Earth!

What happens to solar energy once it enters the atmosphere???

• 25% is reflected by clouds and air

• 20% is absorbed by ozone, clouds and atmospheric gases.

• 5% is reflected by the Earth’s surface

• 50% is absorbed by the Earth


Have you ever touched anything hot??

Conduction is the transfer of thermal energy between objects when their atoms or molecules

collide.

When air molecules come into direct contact with the warm surface of Earth,

thermal energy is transferred to the atmosphere.



Convection is the transfer of thermal energy by the movement of heated material from one place

to another.

Fill in the blanks!!!As air is heated, it becomes less __________and rises. Cool air is denser, so it ______________. As the cool air __________________, it pushes the warm air up.

The cool air is eventually _______________ by the Earth’s surface and begins to ________again.

This cycle of warm air _________and cool air ________________causes a circular movement of air, called a convection current

As air is heated, it becomes less dense and rises. Cool air is denser, so it sinks. As the cool air sinks, it pushes the warm air up.

The cool air is eventually heated by the Earth’s surface and begins to rise again.

This cycle of warm air rising and cool air sinking causes a circular movement of air, called a convection current

• The Earth’s crust

Demo: Cloud in a Bottle

•Materials:•Plastic Bottle•Warm Water•Match

Clouds and PrecipitationSection 11.3

Demo: Cloud in a Bottle

• Clouds are formed when water droplets in the air cool and then collect on dust particles.

• In this demonstration, 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 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 (condensation nuclei) in the atmosphere. The air is cooled by expansion during its upward movement.

Cloud FormationA condensation nucleus is a small particle in the atmosphere around which water droplets can form.

When the number of these droplets is large enough, a cloud is visible.


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

Latin Root Meaning

CumulusStratusCirrusnimbus

HeapLayerCurl of hairrain

Types of CloudsLow clouds- Low clouds are of mostly composed of water droplets since their bases generally lie below 6,500 feet.


Middle clouds- they are composed primarily of water droplets,sometimes ice. The bases of mid-level clouds typically appear between 6,500 to 20,000 feet

High clouds- High-level clouds form above 20,000 feet and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals.

Precipitation

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

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

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