- The natural greenhouse effect has been keeping the earth warm for millions of years, allowing life to thrive on this planet. The enhanced or accelerated greenhouse effect, which is what is happening now, is causing global warming and may mean the end of life on earth if we can't slow or stop it.o this  natural greenhouse effect is very useful.    The gases that keep the earth warm are called greenhouse  gases. The most important gas, causing about 75% of the  natural greenhouse effect, is water vapor.

What Are Greenhouse Gases? Greenhouse gases absorb reflected sun energy, making the Earth's atmosphere warmer. A lot of the sun’s energy reaches the ground directly, and a portion is reflected by the ground back into space. Some gases, when present in the atmosphere, absorb that reflected energy and redirect it back to Earth as heat.reenhouse gases absorb reflected sun energy, making the Earth's atmosphere warmer.

- There are several gases that are classed as greenhouse gases.    They are:   water vapor  carbon dioxide  ozone  methane  nitrous oxide  CFCs     Energy … from the sun heats the earth's surface and atmosphere, which  drives the earth's weather and climate.es. Chlorofluorocarbons are greenhouse gases. They were largely responsible for damaging the ozone layer, but they have been checked since the Montreal Protocol (1987 - 1999), which has been ratified by 196 countries.

The Greenhouse Effect and Greenhouse Gases Carbon dioxide present in the earth's atmosphere contributes to the Greenhouse Effect. Greenhouses work well to promote plant growth because the energy from the visible rays of the sun can be used by plants in the greenhouse to fuel photosynthesis, and the greenhouse glass traps heat to keep the plants warm.

1. the suns rays reach the earths surface without any proble Greenhouse Gases. We noted earlier that water vapor (H2O) and carbon dioxide (CO2) are two of the major greenhouse gases. Both of these molecules are present on Earth naturally, their amounts having evolved to steady levels as a total effect of plant and animal life.There are several other gases that contribute to the greenhouse effect.f all the greenhouse gases, carbon dioxide is present at the highest concentration by far. Based on 1990 concentrations, carbon dioxide is said to be responsible for almost 60% of the total greenhouse effect when efficiency and concentration are considered.

- Carbon dioxide adds to the greenhouse gases that are warming the atmosphere. Carbon dioxide moves in and out of the atmosphere using the carbon cycle, from trees, oceans, soil and animal life.Extra carbon dioxide is now being added to the atmosphere by man burning fossil fuel, and by deforestation, removing forests that used to absorb and store carbon.arbon dioxide doesn't really hurt the atmosphere. Venus and Mars both have atmospheres comprised primarily of CO2. CO2 is also a necessary constituent of our atmosphere for … plant respiration (photosynthesis) and for keeping the earth warm.

What does the greenhouse effect do to the environment? The earth's greenhouse effect is what makes this planet suitable for life as we know it. The earth's atmosphere contains trace gases, some of which absorb heat. These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases.. Albedo has an important influence on the earth's temperature. Greenhouses are structures designed to retain heat. The heat-trapping ability of a greenhouse is influenced by a number of factors including the transparency of the greenhouse cover, color of the surfaces inside the greenhouse, and type of surfaces inside.

Carbon dioxide Carbon dioxide in the atmosphere is also important because it captures heat radiated from Earth's surface. That heat keeps the planet warm enough for plant and animal (including human) life to survive. Increasing levels of carbon dioxide in the atmosphere may be responsible for long-term changes in Earth's climate.

Greenhouse Gas Emissions: Causes & Sources Behind the struggle to address global warming and climate change lies the increase in greenhouse gases in our atmosphere. A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.

Unit 12 (Ryan) Earth's History Why is the ozone layer important for Earth's life forms? The ozone layer is important for Earth's life forms because it protects Earth from harmful ultraviolet radiation. This made the environment able to support more complex life forms. 2.) Describe the role of cyanobacteria in changing Earth's early atmosphere. Cyanobacteria helped in changing Earth's atmosphere by adding an abundance of oxygen to it. To this day cyanobacteria's account for 20% to 30% of photosynthesis today.

Unit 12 (Ryan) Earth's History Explain two reasons why having an oxygen-rich atmosphere is important for life on Earth. 1.) We need an oxygen-rich atmosphere for life on Earth to breathe and survive. We need oxygen to simply be alive. 2.) We need an oxygen-rich atmosphere (creating the ozone layer) to protect life on Earth from harmful ultraviolet radiation.

Greenhouse Gas Emissions: Causes & Sources How greenhouse gases affect global warming. The gases in the atmosphere that absorb radiation are known as greenhouse gases (sometimes abbreviated as GHG) because they are largely responsible for the greenhouse effect. The greenhouse effect, in turn, is one of the leading causes of global warming. The most significant greenhouse gases are water vapor (H2O), carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), according to the Environmental Protection Agency (EPA).

- Earth's Greenhouse Gases. Even though only a tiny amount of the gases in Earth s atmosphere are greenhouse gases, they have a huge effect on climate. There are several different types of greenhouse gases. The major ones are carbon dioxide, water vapor, methane, and nitrous oxide.All of these have molecules with three or more atoms. The atoms are held together loosely enough that they vibrate when they absorb heat.ven though only a tiny amount of the gases in Earth s atmosphere are greenhouse gases, they have a huge effect on climate. There are several different types of greenhouse gases.

Greenhouse effect The greenhouse effect is caused by greenhouse gases; the most important greenhouse gases in Earth's atmosphere are: water vapor, carbon dioxide, and methane. When there is more greenhouse gas in the air, the air holds more heat. This is why more greenhouse gases cause global warming.

- Glossary: Astronomy. Glossary: Life in Universe. We have already seen that carbon dioxide plays an important role in producing the greenhouse effect, which makes Earth a comfortable place to live, and that it does so by interfering with the return of energy to space from the Earth's surface by infrared radiation.

- Greenhouse Gases. We noted earlier that water vapor (H2O) and carbon dioxide (CO2) are two of the major greenhouse gases. Both of these molecules are present on Earth naturally, their amounts having evolved to steady levels as a total effect of plant and animal life.n addition to knowing the concentration of the greenhouse gas, it is important to understand that each gas has a different relative greenhouse efficiency. In other words, some gases are better at absorbing the solar radiation than others, and therefore have a greater overall impact on the greenhouse effect.

- It is significant that so much carbon dioxide stays in the atmosphere because CO 2 is the most important gas for controlling Earth’s temperature. Carbon dioxide, methane, and halocarbons are greenhouse gases that absorb a wide range of energy—including infrared energy (heat) emitted by the Earth—and then re-emit it.ising concentrations of carbon dioxide are warming the atmosphere. The increased temperature results in higher evaporation rates and a wetter atmosphere, which leads to a vicious cycle of further warming. (Photograph ©2011 Patrick Wilken.

Why is the greenhouse effect necessary for life on earth? The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface. The name comes from an incorrect analogy with the warming of air inside a greenhouse compared to the air outside the greenhouse.

What is the greenhouse effect? The greenhouse effect is caused by the interaction of the sun's energy with greenhouse gases such as carbon dioxide, methane, nitrous oxide and fluorinated gases in the Earth's atmosphere. The ability of these gases to trap heat is what causes the greenhouse effect.Greenhouse gases are made of three or more atoms. This molecular structure makes it possible for these gases to trap heat in the atmosphere and then re-emit it towards the surface which further warms the Earth.he greenhouse effect increases the temperature of the Earth by trapping heat in our atmosphere. This keeps the temperature of the Earth higher than it would be if direct heating by the Sun was the only source of warming.
