Which of the inner planets have an atmosphere containing mostly carbon dioxide?
Earth is the terrestrial planet that has oxygen in its atmosphere. Some other elements in the atmosphere are nitrogen and carbon dioxide. Mercury, Venus, and Mars are the other terrestrial planets, but their atmospheres are composed of other elements. For example, Venus' atmosphere is composed primarily of carbon dioxide.
The carbon cycle moves carbon from the earth and the oceans into the atmosphere. Burning fossil fuels (coal, oil and natural gas) releases carbon. When animals, and humans, breathe we release carbon into the atmosphere. Burning fossil fuels or wood (all containing carbon) the carbon dioxide is released in the atmosphere. The answer is the natural carbon cycle, in which animals exhale carbon dioxide into the atmosphere and plants then absorb the gas and use…
What planet has a greenhouse effect that warms the planet due to the trapping of infrared radiation by carbon dioxide in the planet's atmosphere?
Both Venus and Mars have carbon-dioxide atmospheres. The Earth also started with a carbon-dioxide atmosphere but the development of anerobic bacteria produced oxygen as a waste-product which eventually altered the atmosphere and killed off the bacteria but allowed other types of organism using oxygen to develop, and that eventually led to animal life.
The atmosphere didn't literally need the Carbon Dioxide! The main purpose of the Carbon Dioxide is for the plants! Plants needed Carbon Dioxide for their process called photosynthesis to produce their own food and in return they exchange it into Oxygen but for me personally the Carbon Dioxide in our atmosphere is also there to maintain the balance in it.
Mercury has no real atmosphere, so it's a bit like the moon in that respect. Venus has a very thick atmosphere of mainly carbon dioxide, it has a huge surface pressure of around 93 bar, around 93 time that of earths. Earths atmosphere is mainly nitrogen (79%) and oxygen (20%) with some carbon dioxide (1%) roughly speaking. Mars has a thin atmosphere, mainly carbon dioxide.
There are a wide range of atmospheres for terrestrial planets (smaller, rocky planets) depending on their sizes, orbits, and composition. In our solar system, there are 4 very different atmospheres for the 4 terrestrial planets. Mercury - no appreciable atmosphere due to small size and closeness to the Sun Venus - hot, extremely dense carbon dioxide atmosphere (Greenhouse effect) Earth - cool, low density nitrogen atmosphere, oxygen maintained by green plants Mars - very thin…
It depends on how you define air. Other planets in the solar system have atmospheres, but they have different compositions from Earth's atmosphere, which may or may not be called air. The gas planets have atmospheres made mostly of hydrogen and helium while Venus and Mars have atmospheres made mostly of carbon dioxide. The air we are familiar with is mostly nitrogen and oxygen. When Earth was young it likely had a carbon dioxide atmosphere…
The atmospheric source of carbon that is part of the carbon cycle is carbon dioxide. Carbon dioxide moves into the atmosphere from the oceans, the land, rocks and soil, from vegetation and from animals. However, not all of the carbon dioxide in the atmosphere is natural. Humans are adding carbon dioxide to the atmosphere by burning fossil fuels.
