Early atmosphere gases
WebEvolution of the Atmosphere: Definition. The atmosphere is a layer of gases that surrounds a planet. Earth’s atmosphere is composed of several layers that are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The modern-day atmosphere contains a mix of gases (nitrogen, oxygen, argon, carbon dioxide, and … WebWater is cycled through all of Earth’s systems in each of its three phases: solid, liquid, or gas. Water vapor in the atmosphere is a greenhouse gas due to its heat-trapping ability. Carbon Dioxide. Carbon dioxide naturally composes about 0.03% of the atmosphere, but the amount is increasing due to the burning of fossil fuels.
