Atmospheric Factors Affecting Earth

This is my paper.

Ozone

The ozone is a layer inside the stratosphere that protects Earth from UV radiation. Without the ozone, we would all be burned due to UV radiation. Ozone depletion is when a hole in the ozone appears. This is a sign of global warming caused by smog and other gases.

Greenhouse Effect

The greenhouse effect is when light from the sun travels into a glass like containment. The light gets into the glass like containment and tries to get back out. The glass protects the light so it will never come out until the light is absorbed. This is what happens with atmosphere. The sunlight travels to Earth and tries to go back out. But the troposphere acts like the glass of the Earth. The sunlight is either absorbed into the Earth, goes back out to space, or gets absorbed into gas molecules.

London Type Smog

London-type smog was caused mainly by air pollution due to combustion of coal and emission of sulphur dioxide (SO2) and dust. Such pollution mixed with fog can produce droplets of sulphuric acid (H2SO4) suspended in the air. When in 1952, in London, the concentration of SO2 during a smog event exceeded 3.5 mg per 1m3 of the air (or 3500 ug per 1m30), it caused massive cases of decease(Note: 1mg is 0.001g; another unit is 1 ug which is equal to 0.000001 g. So 1g=1000 mg or 1000000 ug).

The Atmosphere

Early Greeks considered "air" to be one of four elementary substances; along with earth, fire, and water. Air was viewed as a fundamental compound of the universe. Measurements such as temperature and pressure not only help us predict the weather, but also help us look at long-term changes in global climate. Nitrogen takes 78% of the Earth's atmosphere. Oxygen is 21% of the atmosphere. Carbon monoxide is very deadly to humans, animals, and plants.

Constant Components : Nitrogen (N2) 78.08%, Oxygen (O2) 20.95%, Argon (AR) 0.93%, Neon, Helium, Krypton 0.0001%

Variable Components : Carbon Dioxide (CO2) 0.038%, Water Vapor (H2O) 0.4%, Methane (CH4) Trace, Sulfur Dioxide (SO2) Trace, Ozone (O3) Trace, Nitrogen Oxides (NO,NO2) Trace

Space Exploration

 

The Space Program

• The space program is a program that let humans go in space
• The space program started in 1958
• NASA stands for National Aeronautics and Space Administration
• The first human to orbit Earth was Yuri Gagarin, aboard Vostok 1
• The first American in space, Alan Shepard, was aboard Freedom 7
• The first American to orbit Earth was John Glenn, aboard Friendship 7
• Between 1969 and 1972, the United States and the Soviet Union sent many unpiloted spacecrafts to explore the moon
• In July 1969, three American astronauts circled the moon aboard Apollo 11
• Once in orbit, Neil Armstrong and Buzz Aldrin entered a tiny spacecraft called Eagle
  
• On July 20, the Eagle descended toward a flat area on the moon's surface called the Sea of Tranquility
• The Eagle landed and said that they landed safely on the moon and the mission control in Houston, Texas cheered and whooped
  
• "One small step for man, one giant leap for man kind." , stated Neil Armstrong

Zoom-Istvan Banyai
I see the sun, now a rooster, and children looking at the rooster. The children ona stool. that is in a barn that is on a farm. This farm is on a playset. It is in a toyshop. A lady is playing with that playset. It is on a magizine, that a man is holding. This man is on cruise ship. The cruise ship is on a poster which is on a bus. That is in a city, on a t.v. A man is watching it, in the desert, ona poststamp. The poststamp is in Jamaica. And a man is watching them, in a plane, that is over a sea, that is in the world. The world is in space. The space is infinite.

Enigma Box

A black box that has two holes, one small and one large. There is a tube at the bottom that drips once every time it is filled with water. After at least 470 ml of water it poured out water. A bucket that is under the tube is being filled when it pours. At least one minute after the it starts it stops.

It might have to do with the shape of the box. The water might be building up and when it overflows it might go over an edge and hit a lever that might open a trap door. It also might have to do with the water. It also might have to do with the tube. Maybe it is just curved upward to point to the top so it can capture water when it fills up.

Inside the box is a tube that curves like a fish that was sketched.
