If there had been no gases, no life would be there. The atmosphere supports life.
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
The earth would be too cold for life. Greenhouse gases have been essential for life on this planet, and have kept Earth warm for millions of years.
Greenhouse effect. The same effect that keeps Earth warmer than if there would be no atmosphere: without an atmosphere, the average temperature on Earth would be below zero Celsius.
It would be the MOON because Consequently, earth's first atmosphere, was shallow and sparse, composed of lightweight hydrogen(h2) and helium (he) gases. Its atmosphere and climate would have been similar to that of our moon.
Greenhouse gases, such as water vapor, carbon dioxide, and methane filter reflect warmth back to Earth. Without these critical components of the atmosphere, the Earth would quickly turn into a giant frozen block, and life forms would freeze and die. So you can see that greenhouse gases are extremely important to have.
Its called the greenhouse effect!Surface temperature.
The greenhouse effect is caused by greenhouse gases that absorb infrared rays and thereby keep the earth warmer than it otherwise would be. The greenhouse effect is important to life on earth. Without greenhouse gases, there would be global cooling and life as we know it would no longer be possible. With increased levels of greenhouse gases, there is global warming and undesirable climate change.
A decrease in the amount of greenhouse gases in Earth's atmosphere would result in Cooler global temperatures. This would help decrease the impact of global warming.
Of course, greenhouse gases keep the Earth from being one large popsicle. The newest studies of the atmosphere indicate that the atmosphere is pretty stable, now. The reason is that nearly all of the greenhouse gases are water vapor mostly evaporated from the oceans.
Climate scientists estimate that the average temperature on Earth would be colder by approximately 30 degrees Celsius (54 degrees Fahrenheit). With our existing mix of gases in the atmosphere the average temperature on Earth is about 13C. The Earth's temperature without greenhouse gases would be -17C. There would be no life on Earth
the mixture of invisible gases that surround earth

This would be called the greenhouse effect

Gases in the atmosphere trap the sun’s warmth -apex
