C1 TOPIC 1 – THE EARTH’S SEA AND ATMOSPHERE THE EVOLUTION OF THE ATMOSPHERE. Phase 1 – Volcanoes gave out gases. 1) The Earth’s surface was originally molten‚ it was very hot. 2) Eventually the surface cooled down and a bit crust formed. Volcanoes kept erupting. 3) Volcanoes gave out gases: CO2‚ water vapour and small amounts of other gases. (water and oceans formed) 4) The early atmosphere: mostly CO2‚ with no oxygen. 5) The oceans formed when the water vapour condensed.

Air pollution is caused by many things‚ earth is very good at cleaning the air on its own‚ though through the years air pollution has gotten to a very bad point where earth can no longer clean all of the pollution we produce which has now started to have very bad effects on our environment such as causing acid rain‚ smog and a lot of health problems. There are a variety of things that cause air pollution like for example cars‚ airplanes and other engine vehicles. All these engine vehicles release

gases it will lead to global warming. It’s very much like not parking your car under a tree‚ the car gets excessively heated up‚ making it uncomfortable to sit in the vehicle. Greenhouse Effect Greenhouse effect is the process in which the atmosphere of the Earth trap some of the heat coming from the sun‚ making the Earth warm but due to burning fuels‚ cutting trees‚ the concentration of heat on Earth is increased to abnormal levels making greenhouse effect as one of the major causes of global

Global Warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light‚ or heat‚ escapes the earth’s atmosphere. Thus‚ the temperature experienced on Earth begins to rise. Climate change is a part of the Earth’s history. There have been dramatic fluctuations in overall average temperature for the past 150‚000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level

It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day‚ the car gets hotter when it is out in the parking lot. This is because the

We really should be aware about this and be more thoughtful on this subject‚ we do not reason on what happened and we are more neglected throwing garbage and not taking care of the environment. Global Warming The average temperature of Earth has been warming up since 1840‚ coinciding with the start of the industrial revolution. However‚ we can not establish a cause and effect relations‚ because the atmosphere does not react so quickly. During

In the particular case of climate change‚ the international community has committed itself‚ through the Framework Convention on Climate Change (signed in Rio in 1994 and ratified by 150 nations‚ including the United States)‚ to “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic

This is a very popular issue all over the world. In order to learn more about global warming‚ we should go through what makes the earth warm and how warming affects the earth.

For other uses‚ see Atmosphere (disambiguation) View of Jupiter’s active atmosphere‚ including the Great Red Spot. An atmosphere (New Latin atmosphaera‚ created in the 17th century from Greek ἀτμός [atmos] "vapor"[1] and σφαῖρα [sphaira] "sphere"[2]) is a layer ofgases surrounding a planet or other material body of sufficient mass[3] that is held in place

Colonizing the Red Planet As humans we are very curious. We have explored and conquered all around Planet Earth. It’s only been a matter of time before we move onto bigger and better things. Mars may seem like it is too far away or too complicated to try and accomplish‚ but with the technology changing every day we are closer than ever to reach the red planet. Colonizing Mars can happen if we get water‚ learn how to grow food‚ obtain oxygen‚ and get the materials needed survive. Mars‚ otherwise know
