it is hydrogen
Neptune's minor atmospheric gases are ethane and hydrogen deuteride. Its major gases are hydrogen, helium, and methane. Neptune's blue appearance is caused by the mixture of these gases.
hydrogen and helium
The atmospheric gases carbon dioxide, methane and nitrous oxide are all greenhouse gases that help to heat the Earth.
The glass on the greenhouse stops temperature from leaving or entering like the gases do to the earth.The atmospheric gases are called 'greenhouse gases' based on the idea that the gases 'trap' heat like the walls of a greenhouse do
Hydrogen, Helium
The lowest atmospheric layer that contains greenhouse gases is the troposphere
Hydrogen,and Helium
Yes
The troposphere.
i have no clue
The major gases in Neptune's atmosphere are hydrogen, helium, and methane. Hydrogen and helium are the most abundant gases, with methane making up a smaller but still significant proportion.
