Mars Dichotomy

The planet Mars is a red plant that is found in the Solar System in the Milky Way Galaxy one planets farther from the sun than Earth. The planet Mars has a very thin atmosphere full of primarily carbon dioxide. The surface of Mars is very dusty and rocky because of volcanoes. The geology of Mars is different from Earth in many ways including the amount of volcanoes, mountains, valleys, and internal makeup.

Scientists, however, have identified issues with this theory. The main detraction is that an impact of that size and magnitude would have left a circular impression on the planet. Most analysis of

20. Although it is much colder on Mars than on Earth, the similar tilt of Earth’s and Mars’ axes means they have similar seasons. Like Earth's, Mars’ north and south polar caps shrink in the summer and grow in the winter. In addition, a day on Mars is 24 hours 37 minutes—nearly the same as Earth’s. No other planet shares such similar characteristics with Earth.e 21. Mars’ seasons are twice as long as those on Earth because it takes Mars 687 days to orbit the sun, twice as long as Earth’s 365-day journey.a 22. With no large moon like Earth’s to stabilize it, Mars periodically tilts much more toward the sun, creating warmer summers on Mars than it otherwise would have.d 23. The Earth’s moon is 240,000 miles away. Earth’s next closest neighbor is Venus, which comes as near as 24 million miles. After the moon and Venus, Mars is our next closest neighbor at 34 million miles away—though when Mars and Earth are at the opposite sides of their orbits around the sun, they are separated by 249 million miles.e 24. Mars is home to Hellas, a vast and featureless plain that covers 1300 miles (the size of the Caribbean Sea). It was created by asteroids crashing into the planet’s surface of Mars

To compare, all three planets have secondary atmospheres that were produced by volcanoes. To contrast, Venus is too close to the Sun, and was too warm for liquid water to form and without liquid water; the CO2 could not settle out of the atmosphere and dissolve into the oceans. This caused Venus to suffer from runaway greenhouse effect and became hot with an extremely dense and vastly insulated atmosphere. Along with this, UV sunlight destroyed the H2O in the atmosphere. On the other hand, Earth had enough distance from the Sun for liquid water to form and precipitate out into the ocean while the CO2 in the atmosphere dissolved into the oceans and was removed from the atmosphere. The trace amounts of H2O and CO2 in the atmosphere create an insulating layer which is enough to keep the Earth at a mild temperature. Out of the three planets, Mars is the farthest from the Sun. It is possible that Mars had liquid water earlier in its history. The CO2 dissolved into water; however, Mars has less mass than Venus or the Earth. Because of Mars’ smaller mass, it has less tectonic activity and Volcanism stopped early in its formation. This did not allow the atmosphere to be renewed from CO2 or H2O

Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be

“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present.

Much to common disbelief, Mars and Earth have many things in common. Some of these factors include similarities in size, inclination, structure, composition and the presence of water on their surfaces (Universe Today, 2016). Mars is the next closest planet to Earth. It withholds all necessary elements needed for life to exist. These include water, carbon dioxide (CO₂) and nitrogen (HowStuffWorks, 2017). There are also unbelievable similarities between Mars’ atmosphere and the Earth’s atmosphere from billions of years ago. Like Mars, when the Earth was first formed it had no oxygen and its atmosphere was comprised of carbon dioxide and nitrogen. Earth was not able to produce oxygen until photosynthetic bacteria developed (HowStuffWorks, 2017). Mars’ atmosphere consists of 95.3% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.2% oxygen.

Mars: Mars is the fourth planet from the sun and is named after the Roman God of War because of the red color is has. Mars is considered a terrestrial planet with a thin atmosphere made up of carbon dioxide.

Mars is named after god of war the god roman. Mars is called the red planet because of the air is iron oxide giving it a red color. Mars have many craters by volcano that erupt. the biggest volcano is mount Olympus is active. Olympus is either the tallest or second tallest volcano on the planet but sciences can not tell due to atmosphere and measuring tool that can measure to

Mars is an interesting and mysterious planet. It is often referred to as the Red Planet. The Romans named Mars after the god of war. The rocks, soil, and sky all have a red hue on account of rust. Mars is the fourth planet from the sun at about 141 million miles (228 million kilometers) and the last terrestrial planet from the Sun. Mars follows closely behind Earth but is comparatively smaller, with about half the diameter of Earth (6,794-km) and about one-tenth of Earth s mass (6.419 x 1023 kg). Thus the force of gravity on Mars is about one-third of that on Earth. Mars is probably the planet we know the most about since it is so close to Earth, though what we know now is not even close to everything about the planet. Over

Mars is the fourth planet from the sun. Befitting the red planet's bloody color, the Romans named it after their god of war. The Romans copied the ancient Greeks, who also named the planet after their god of war, Ares. Other civilizations also typically gave the planet names based on its color — for example, the Egyptians named it "Her Desher," meaning "the red one," while ancient Chinese astronomers dubbed it "the fire

Mars and Earth are both part of the four terrestrial planets that orbit within the inner solar system and are from the same origin. They are both made of rock and metal. Mars has an extremely weak magnetosphere however, so probably doesn’t have a liquid metal core. Earth on the other hand does have a liquid metal core, which provides its strong magnetosphere. Solar radiation can therefore directly penetrate Mars, while Earth can reflect solar radiation. Mars is much further from the sun than Earth making it much colder. This distance from the Sun also makes a big difference in the length of their years, with Mars year being about twice as long. Further, Mars orbit around the sun is more eccentric than Earth’s, which leads

Mars is big enough to have undergone most of the early processes that shaped the other terrestrial planets: accretion (or the melding of space debris), melting, core separation and differentiation, and subsequent cooling by conduction, convection and volcanism. So an understanding of Mars' evolution can essentially be translated into an understanding of Mercury, Venus, Earth and the Moon's evolution, too.

Before even considering extraterrestrial life in the first place, the necessary elements must be available. As mentioned above, the red planet was once warmer and wetter, providing ideal conditions for life. The availability of water is of utmost importance when regarding life. On Mars’ surface, the existence of carved channel networks provides evidence for possible floods in the past (Baker 2001). In addition, the presence of “contraction-crack polygons” cover great distances over the martian landscape and mimic terrestrial ice-wedge terrains of permafrost regions (Baker, V. R. 2001). It is also uncratered, signifying potential water associated activities in the recent past. The atmosphere on Mars used to be much thicker than it is presently. The extensive
