Most of the energy emitted from the earth’s surface does not go directly out to space.  This emitted energy is reabsorbed by clouds and by the gases in the atmosphere.  Some of it gets redistributed by convection.  Even more energy is released into the atmosphere through condensation.  The majority of the energy is reabsorbed by the greenhouse gases such as methane, nitrous oxide, ozone, carbon dioxide and water vapor.  These gases constantly emit the sun’s energy back into the atmosphere and keep the earth a habitable temperature.  Eventually, most of the energy makes its way back out to space and Earth’s energy balance is fairly well maintained.  The energy that doesn’t make its way out is responsible for global warming

-because some gasses keep on being recycled non stopped and they are absorbed an emitted back to earth surface ( oxygen and nitrogen)

-plants take carbon dioxide, and give out fresh oxygen to humans. humans take fresh oxygen and give out carbon dioxide to plants (carbon dioxide)

# data[].attributes.body
Because it is a cycle

because of the atmosphere ozone

Questions: How is the % of gases regulated fairly in the atmosphere.
-Because of its cycle, one of them are the plants. They regulate the gases in the air

Beause of its a cycle

How is % of the gases regulated fairly in the atmosphere?

Because some are taking and some are released so it stays constant.thats how the gases in the atmosphere is disturbed fairly

Make sure to write your questions as well :)

It increases due to human activities by the time, by burning fossil fuels,car and companies gases etc.

Question 3
-Because of factories that burn fossil fuel, it increases air pollution.
-Cars cause fuel fumes.
-Creates green house effect on earth.

Q . Describe 2 human activities that leads to increase of co2 concentration in the air

ANSWER : Breathing and digesting food

# data[].attributes.body
when humans pollute the air the CO2 levels increase in the air. air pollutions harms humans and causes internal trouble. humans using cars excretes bad gas in the air which will increase CO2 levels

# data[].attributes.body
Q3 answer:
Human activities such as :
Burning of oil , coal , and gas as well as deforestation are then primary causes of the increased carbon dioxide concentrations in the atmosphere

# data[].attributes.body
-Describe some possible reasons for rapid increase  of CO2 concentration on the graph?

.The burning of fossil fuels
.Cars burning fuel and producing pollution
. deforestation
( cutting down of trees )

# data[].attributes.body
One of the major causes is green house gases from burning fossil fuels and the etc.....

-Breathing polluted air puts you at a higher risk for asthma and other respiratory diseases.
-When exposed to ground ozone for 6 to 7 hours, scientific evidence show that healthy people’s lung function decreased and they suffered from respiratory inflammation.
-Air pollutants are mostly carcinogens and living in a polluted area can put people at risk of Cancer.
-Coughing and wheezing are common symptoms observed on city folks.
-Damages the immune system, endocrine and reproductive systems.

-factories can affect the CO2 of air
- burning of fossil fuels increases the CO2 in the atmosphere.

Because of the air polition the CO2 increased

Air is a gaseous substance that is composed primarily of nitrogen, oxygen and argon. The air in the atmosphere that surrounds the Earth is approximately 78 percent nitrogen, 21 percent oxygen and 1 percent argon, with the remainder made up of various other gases including neon, helium and hydrogen.

# data[].attributes.body
By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

The air in our atmosphere is composed of molecules of different gases. The most common gases are nitrogen (78%), oxygen (about 21%), and argon (almost 1%). Other molecules are present in the atmosphere as well, but in very small quantities.

# data[].attributes.body
dry air is 78.09 percent nitrogen and 20.95 percent oxygen, accounting for over 99 percent of the total volume. The remaining 1 percent is made up of argon, carbon dioxide, neon, methane, helium, krypton, hydrogen, xenon, ozone, nitrogen dioxide, iodine and trace amounts of carbon monoxide and ammonia.

While the composition doesn’t change much as you travel up through the lower layers of the atmosphere, what does change is the number of molecules. As you travel higher, the air molecules become less plentiful.
