Physical characteristics of Mars 5, Physical characteristics of Mars

It's about the same as Earth, but there's no air on it, so there's no life.

The ground, like the earth!

Mars has an orange-red sphere in appearance, about half the diameter of the Earth, and the surface of the earth is covered with sand dunes and gravel, and there is no stable liquid water. Mars is one of the eight planets in the solar system, the fourth closest to the Sun and the second smallest planet in size after Mercury, and one of the four terrestrial planets in the solar system.

The eight planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far.

Mars is close to the Earth and is very similar to the Earth in many ways, such as the rotation period of Mars is very close to the Earth, and Mars also has two poles, as well as day and night and four seasons.

The Martian atmosphere is weakened by solar radiation, and the daily temperature is often at minus degrees Celsius, with almost no oxygen supply, which is very unsuitable for human survival.

Summary. <>

Hello dear! I am glad to answer for you: The Martian soil is dominated by basalt, of which the amount of igneous rock-forming minerals accounts for 80 85%, mainly including olivine, pyroxene, plagioclase, iron oxides, etc. The climate of Mars is dry and dehydrated.

Surface characteristics of Mars, climate, soil.

Hello dear! I am glad to answer for you: The Martian soil is dominated by basalt, of which the amount of igneous rock-forming minerals accounts for 80 85%, mainly including olivine, pyroxene, plagioclase, iron oxides, etc. The Qi Lingfeng of Mars is a dry ruler pants and a lack of water.

Extended Material: Mars (English: Mars; Latin:

martis；Astronomical symbol: ) is the fourth closest planet to the Sun and the second smallest planet in the Solar System after Mercury, one of the four terrestrial planets in the Solar System. In ancient Europe, Mars was called "Mars", the "god zhan" in ancient Roman mythology, and also known as the "Red Planet" Min Cave.

In ancient Chinese, it was called the year of Nayou because it was like fire, and the position and brightness of the acacia often changed.

The surface of Mars is covered with hematite (iron oxide), the southern hemisphere is an ancient, crater-filled bumper highland, and the northern hemisphere is a younger lowland plain.

The climate of Mars.

Okay, no. There are many factors in the Martian climate, especially the noisy ones such as ice caps and sandstorms, and the average temperature is about -60 degrees Celsius, and the ascension can even be as low as -125 degrees Celsius near the poles in winter.

There are distinct seasonal changes on the star, which is the main similarity between it and Earth. But other than that, Mars is very different from Earth.

Mars is Earth's closest neighbor. It shares many of the same characteristics as the earth. They all have moons, they all have moving sand dunes, wind-blown dust storms, and they all have white ice caps at the north and south poles, except that the Martian ice caps are made up of dry ice.

Mars rotates once every 24 hours and 37 minutes, and its axis of rotation is inclination of 25 degrees, which is not much different from Earth.

Diagram of the internal structure of Mars. The disadvantage of Mars is that the internal structure is similar to that of Earth, with a shell, mantle, and nucleus, but due to incomplete data, the composition and size of the Martian nucleus are still uncertain.

This is Phobos, also known as Phobos, which was filmed by the Corsair. It has a huge meteorite impact crater on its surface.

This is an unusual feature on the surface of Mars, known as the "White Stone".Its origin is unknown, but what can be confirmed is that it has nothing to do with the poles, since it is located near the equator.

Mars is known as the red planet because its surface is covered with oxides, giving it a rusty red color. Fire.

Most of the star's surface is a large desert with large amounts of red oxides, as well as ochre-colored gravel ground and condensation.

The ice caps at the poles of Mars and the presence of water in the Martian atmosphere Probes from the surface of Mars prove that in ancient times, Mars had liquid water, and the volume was particularly large. This water coalesces on the surface of Mars.

Large lakes are sold at a loss, and even rented air training to the ocean. The numerous riverbeds that we can now see on the surface of Mars can be.

It was made by the water at that time. In addition, many teardrop-shaped "islands" on the surface of Mars are also darkening us.

show this.

Mars is one of the eight planets in the solar system, and it is the fourth planet in the solar system from the inside to the outside.

The planet has a diameter of about 53% of the weight of the Earth and a mass of 14% of the Earth. The inclination angle of the axis of rotation and the rotation period are similar to those of the earth, and one revolution is about twice the time of the earth's revolution. The orange-red exterior is hematite (iron oxide) on the surface.

In ancient Chinese books, Mars is called "Luminous Star", and Mars is called "Mars Star" in ancient Western times (ancient Rome), which is the only ruling planet of the 12 zodiac signs Aries, not the guardian planet of Scorpio.

Mars is basically a desert planet with sand dunes, gravel and no stable liquid water (NASA announced on September 28, 2015 that there is a small amount of water on Mars. According to Agence France-Presse (AFP) on July 25, 2018, researchers at the European Space Agency (ESA) have discovered the first liquid groundwater lake on Mars). The atmosphere, dominated by carbon dioxide, is thin and cold, with sand and dust suspended in it, and dust storms occur frequently every year.

Mars has a polar crown of water ice and dry ice at both poles, which waxes and wanes with the seasons.

Compared to Earth, Mars is less geologically active, and most of the surface landforms were formed during the more active period of antiquity, with dense craters, volcanoes and canyons, including Mount Olympus, the highest mountain in the solar system, and Mariner Canyon, the largest canyon.

Another topographical feature is the stark difference between the northern and southern hemispheres: the south is an old, crater-filled highland, while the north is a younger plain.

Modern explorations have shown that the red color of the Martian surface is due to the fact that the Martian atmosphere is capable of emitting infrared lasers, which make Mars form a huge gas laser. The surface of Mars is also rich in iron oxide and has a red color.

For many years, people have fantasized about the existence of "Martians". But in reality, Mars is far from the living environment on Earth. The atmosphere here is extremely thin, only equivalent to the atmosphere at an altitude of 30,000 meters above the earth; At the same time, the atmosphere is dominated by carbon dioxide and is unusually dry.

The average annual temperature in the equatorial region of Mars is only 15. Spring storms are so violent that they can form a long-lasting, very large "rhubarb cloud" over Mars. The surface of Mars resembles the Moon, with spherical mountains and tens of thousands.

So far, no one has been able to get close to Mars.
