How do greenhouse gases affect the earths atmosphere?
They slow the loss of heat
Did earths original atmosphere contain methane and ammonia?
Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity. Over time, the atmosphere changed due to the presence of early life forms that produced oxygen through photosynthesis.
What are the two most abundant gases in earths atmosphere presently?
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
What would earths atmosphere be like if life had not evolved?
Without life, Earth's atmosphere would lack oxygen, as it is primarily produced by photosynthetic organisms. The composition of gases would likely be primarily nitrogen and carbon dioxide, similar to the early Earth's atmosphere. There would also be fewer greenhouse gases, leading to lower temperatures on the planet.
What is earths atmosphere two gases?
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.

When earths early atmosphere formed which gases where lost because earths gravity was too weak?
Hydrogen and helium
Did earths original atmosphere contain methane and ammonia?
Yes, Earth's original atmosphere is believed to have contained methane, ammonia, water vapor, and other gases. This atmosphere was formed from gases released during volcanic activity. Over time, the atmosphere changed due to the presence of early life forms that produced oxygen through photosynthesis.
Why are the major gases that make up earths atmosphere?
Nitrogen, Oxygen and Argon make up 99% of the atmosphere
