Mars has an atmosphere of about 95.72% carbon dioxide.
Venus has an atmosphere of about 96.5% carbon dioxide
Both Mars and Venus have atmosphere made mostly of carbon dioxide. The atmosphere of Venus is much denser.
It is similar to the composition of the atmosphere of Venus. They are both made almost entirely of carbon dioxide.
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
Both Venus and Mars have atmospheres that are mostly carbon dioxide. However, Venus has a very thick atmosphere. The Martian atmosphere is very thin, so the answer is Mars.
Venus has the most carbon dioxide atmosphere of any planet in the solar system, with about 96.5% of its atmosphere composed of carbon dioxide. This thick atmosphere contributes to the planet's extreme greenhouse effect and high surface temperatures.
-about the same size -both have atmosphere -both have volcanos -both have clouds really Venus and Earth have no similarities whatsoever, so this is the best i can do
On both Venus and Mars, the most abundant gas in the atmosphere is carbon dioxide. On Earth nitrogen is the most abundant gas.
They are not the same at all, Venuses atmosphere is very hot dry and thick, while Mars atmosphere is thin and cold. Though they have totally different atmospheres, both planets are going through the same processes, which makes them very similar.
Earth and Venus are both terrestrial planets with similar size, mass, and composition. They both have atmospheres, although Venus has a much thicker atmosphere composed mainly of carbon dioxide. Both planets also have volcanoes and mountains on their surfaces.
Mars and Venus are both terrestrial planets in our solar system, meaning they have solid surfaces. They also have similar sizes and compositions, primarily made up of rock and metal. Additionally, both planets have volcanoes and impact craters on their surfaces.
In both lunar rocks and the atmosphere of Venusthe Argon 40/argon 36 ratio is 1:1 while in the atmosphere of Earth argon 40 is 99.6%
Earth and Venus are both terrestrial planets, meaning they have a solid surface. They also have similar sizes, with Venus being slightly smaller than Earth. Additionally, both planets have atmospheres, but Venus has a thick, toxic atmosphere made mostly of carbon dioxide.
