Why mars surface is red?

Why mars surface is red?

The red color that we usually see in images of Mars is actually the result of iron rust. The rocks and soil on the surface of Mars contain mostly iron and a small amount of dust.

Other elements such as chlorine and sulfur. The rocks and soil were then wiped out by the wind and the resulting dust was blown across The surface of the planet by the activity of ancient volcanoes. Recent evidence suggests that dust along with water also extends to Mars.

By the presence of channels and ducts on the surface of the planet. The iron contained within the dust reacted with oxygen in the atmosphere, creating a distinctive red rust color, while the sky appeared red as the storms lifted up the red dust. Planet's atmosphere. This dust surface, which is between a few millimeters and two meters deep, also sits on top of a layer of hardened lacquer mostly composed of basalt. Iron concentration
This basalt is found to be much higher than basalt on Earth, and also contributes to the red appearance of Mars.
Nearly true-color in-situ images from Mars Pathfinder and Mars Exploration Rover missions indicate that the Mars sky may also appear red to humans. The absorption of sunlight by dust particles in the range 0.4–0.6 dustm may be the primary cause of sky redness. The additional contribution may come from the dominance of the scattering of photons by dust particles at wavelengths of 3 mm, which is in the near infrared range of Rayleigh scattering by gas molecules

What is comets?

चित्र
What is comets? Comets are objects made of ice, dust and rock in the solar system. They have a hard core and long tail of gas and dust. Every now and then they appear within sight of the Earth, before disappearing into deep space. TWO TAILS When a comet becomes close to the Sun, its ice melts and forms two tails: one made of gas and one made of dust. Halley’s Comet Halley makes a full circle around the comet The sun every 75 years, and it has been recorded by historians for more than 2,000 years. Beyklem  which tells the story of the battle of hasting shows it moving in the sky In the year 1066. Circling the sun Comets revolve around the Sun. Their tails are always away from the sun, but in slightly different directions. As the comet is closer to the sun, the tail grows longer.

How does the Arctic Ocean freeze?

How does the Arctic  Ocean freeze? Arctic sea ice is one that forms on the Arctic Ocean during the winter months. Pure water, which does not contain any other molecules, substances or impurities, freezes at 0 ° C (32 ° F). On the other hand, about 3.5 percent of the world's seawater contains dissolved minerals and salts. This additional material reduces the freezing point of seawater to about −2 ° C (28.4 ° F) because the freezing point depends on the number of molecules present in a solution, as well as the type of molecule. During the winter months, when air temperatures in the Arctic begin to drop dramatically, a deep layer of seawater begins to develop minuscule ice crystals; This dirty water is called Fragile Ice. Another drop in temperature causes Friesil's ice to become thick. Pockets of salty slash accumulate until they become so heavy that they begin to sink. This leaves the top layer of icy crystals with a significantly lower salt content. The freezing poi...

What is the event horizon ?

What is the event horizon?  Black holes have three basic elements. In the middle of a black hole and to an infinite density is a singularity made of stellar matter. Outside the singularity is the inner space of the black hole, where the laws of physics as we know it are bent and broken, and where space and time are stretched and constricted Putty.  If your spacecraft has entered the interior of a black hole, it is too late for you. You are crossing the third component: the event horizon. It is also known as the Schwarschild radius, the part that tells us where the black holes are outlined in black. This indicates no return for anything falling next to it, as it requires a faster travel than the speed of light to cross again, as far as we know it is impossible. . No horizon is attributed only to black holes' just a remarkable phenomenon that they possess. According to some principles To control the expansion of the universe, there are regions that will never be obse...
