what is the chemical composition of mars?
155799
It is made up primarily of silicon, oxygen, iron, and magnesium and probably has the consistency of soft rocky paste. It is probably about 770 to 1,170 miles (1,240 to 1,880 km) thick, according to NASA.

Two nearlyidentical spacecraft around Mars and Venus have compared the two worlds'atmospheres and found them to be surprisingly similar. ... Both Venus's and Mars's atmospheres are about 95 percentcarbon dioxide. Earth's is mostly nitrogen now, but scientists think it used tobe more like the other rocky worlds.

Chemical composition: Carbon dioxide: 96 percent. Nitrogen: 3.5 percent. Carbon monoxide, argon, sulfur dioxide, and water vapor: less than 1 percent.

Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

By far the predominant gas is carbon dioxide, making up 95.9 percent of the atmosphere's volume. The next four most abundant gases are argon, nitrogen, oxygen and carbon monoxide. Researchers will use SAM repeatedly throughout Curiosity's mission on Mars to check for seasonal changes in atmospheric composition.

The Earth's atmosphere is composed of the following molecules: nitrogen (78%), oxygen (21%), argon (1%), and then trace amounts of carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, and ammonia. Lower altitudes also have quantities of water vapor.

The atmosphere of Mars is divided into only three layers. The first layer on Mars, the troposphere, is twice as large as the first layer of the Earth's atmosphere. The middle of the atmosphere is called the mesosphere. The temperature of this layer is usually the coldest part of the atmosphere.

Every inner planet has a core. ... Mars's core is made of liquid iron sulfide mixed with some nickel. Inner and Outer Cores. Earth and Venus have an inner core and an outer core; the inner core is solid due to the trememdous weight of the matter above it, and the outer core is liquid.

Silicon is the second most abundant element (27.7%), followed by aluminum (8.1%), iron (5.0%), calcium (3.6%), sodium (2.8%), potassium (2.6%). and magnesium (2.1%). These eight elements account for approximately 98.5% of the total mass of the Earth's crust.

The clouds consist of water ice condensed on reddish dust particles suspended in the atmosphere. Clouds on Mars are sometimes localized and can sometimes cover entire regions, but have not yet been observed to cover the entire planet.

Pluto is composed of a large rocky core wrapped in thick layers of ices. Its icy surface and extremely thin atmosphere are predominantly composed of nitrogen with small amounts of methane and carbon monoxide. The terrain shows remarkable variation including dark/bright regions and smooth/mountainous areas.

Mars' atmosphere however is 95% carbon dioxide, 3% nitrogen, 1.6% argon, and it has traces of oxygen, carbon monoxide, water, methane, and other gases, along with a lot of dust. Dust hanging in the air colors Martian skies tan in photos taken from the surface. Relative to Earth, the air on Mars is extremely thin.

Atmosphere. Venus' atmosphere consists mainly of carbon dioxide, with clouds of sulfuric acid droplets.

Elemental composition Elements known to be present on the lunar surface include, among others, oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti). Among the more abundant are oxygen, iron and silicon. The oxygen content is estimated at 45% (by weight).

What is Mars' atmosphere made of? The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition, according to a NASA fact sheet: Carbon dioxide: 95.32 percent.

The terrestrial planets are rich in heavier gases and gaseous compounds, such as carbon dioxide, nitrogen, oxygen, ozone, and argon. In contrast, the gas giant atmospheres are composed mostly of hydrogen and helium. The atmospheres of at least the inner planets has evolved since they formed.
