Planetary scientists have a lot about Mars over the past 40 or so years of robotic exploration. The earliest probes discovered Mars is heavily cratered in the southern latitudes, as much as the Moon, but the northern latitudes are much less cratered, such that scientists began to suspect an ancient ocean was responsible for resurfacing the northern parts, erasing signs of past impacts. By counting the number of craters in a given region, we can determine the relative ages of each terrain. Combining images and topographic data, scientists can trace ancient shorelines (multiple sea levels, as the seas dried up or evaporated). Observations of the south pole revealed a frozen carbon dioxide ice cap with seasonal variations that contain a historical record of the Mars atmosphere. Mars has been and is thought to still be volcanically active. Volcanoes are present, of the kind that created Yellowstone or Hawaii on Earth; tectonism without plate tectonics. Traces of methane in the atmosphere are replenished annually, suggesting either replenishment by volcanoes or life forms. Geomorphological and structural observations show that water flowed across the Martian surface. We can have estimates of the size and composition of the core of Mars, and magnetic data showing local magnetism but no global magnetic field. Water ice has been found just below the surface in the northern hemisphere. We have some mineral maps, and radar images of the subsurface layering. In short, a lot of scientific data has been found, and piecing all that together to determine that past geological history of Mars is an ongoing endeavour.

∙ 13y agoThey both have roughly the same day length, taking close to 24 hours for one spin on its axis.
The orbital periods and speeds are similar, but Mars being further out takes longer to go around the sun and is slower.
They both have a similar angle of axial tilt, earths being 23.44 degrees and mars' being 25.19 degrees.
Although Mars is colder and further out, the mean temperature is in the same ball park.
They are both inner rocky planets in orbit around the sun.

It also has large amounts of water, though it is all frozen. The Martian day is only 39 minutes longer than an earth day. The total surface area of Mars is almost the same as the total amount of dry land on earth. Mars' axial tilt is very close to that of earth, meaning similar seasons. It also has an atmosphere.

They are next to each other in the solar system? and they are round....no they are spherical

What are 3 characteristics of scientists that is important to their work but are also found in non scientists?
appearance , dedication , and knowledge
Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?
It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
Are all scientists atheists?
No, historically many scientists have been strongly religious; nowadays more scientists tend to be atheists than the general public and it also seems likely that the more senior the scientist, the more likely they are to be atheist. There are scientists who are religious and try to contort science to prove their religious beliefs. On the other hand, there are scientists who are religious and understand perfectly that religion and science are completely separate and distinct. In the world of science, those within it are all unique individuals, just like the rest of the world. So one way of believing or thinking anything can't be assumed.
How do scientists discuss new ideas?
Scientists usually publish their new ideas in a scientific journal. They can also hold a symposium to discuss the ideas, if they wish.
What kind of questions do scientists ask?
Ones that are answered through observing
How many kinds of animals are their?
In all there are about 3 million species scientists have found but scientists also estimate they have only found about 30% of all the types on Earth.
Why do some scientists believe in extraterrestrials?
Given the size of the universe, it is almost impossible for Earth to be the only place where life has developed. Some scientists also just want to know what is there; they don't believe or disbelieve, but want to find out.
How planet earth similar to mars?
Earth is similar to Mars because we know that life is possible on earth and some scientists believe that life is also possible in mars because it has some things which is also present in Earth and is needed for all living things.
Why wegeners ideas about continental drift were not believe?
His ideas where not generally believed because he was an astronomer and meteorologist. Also scientists believed the earth was shrivelled like an old apple.
How does scientists believe the creation of the world?
Most scientist probably believe that the Big Bang created the universe and eventually the Earth. However most also believe there was some time of intelligence that guided it, as the odds against it happening as pure chance are astronomical.
Why it good for scientists to be skeptical?
When scientists are skeptical, the are more likely to find new thing. When scientists are not skeptical, they are less open to opportunities. For example, if scientists were not skeptical of the idea the Earth was flat, then they would have continued many many more years without knowing the true shape of the world. Also, without scientists skepticism, they would not have found out that the planets rotated around the sun, not that everything rotates around Earth.
Is the earth a cube or sphere?
A long time ago- around Christopher Columbus's time- people use to think that the Earth was a cube. Scientists now know that the Earth is a sphere. There is also evidence that it is if you don't believe that - but i highly doubt that. Astronauts that have landed on the moon have seen the Earth and have taken photographs of the Earth. They show that the Earth is a sphere. All the planets that the scientists have discovered so far have all been spheres.
Why do some scientist believe aliens are real and do they have evidence?
Yes and No. Some scientists think that aliens don't exist, some do. If they do, then they also obviously believe in them on other planets. What do you think? I think that they do exist, why would us humans be the ONLY ones on planet Earth? Positiveness of Answer: 100% jokypants1

Do scientist believe there is life on mars?
Scientists now know that there is life on Mars! They have found bacteria, which is microscopic life. they have also found ice, real frozen water, not dust and rock combined. they have also found waterways or canals where water use to flow. Many scientists are thinking that millions of craters at once hit Mars destroying all of the life, leaving some clues that there was life sent by the satellites and rovers.
Scientists are studying the greenhouse effect of which planet?
Earth mostly, but also Venus and Mars.
How many people believe in the big bang theory?
It depends, because some might say 'scientists'. But not all scientists believe in this theory. Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'
