As far as has been found, there is no water and ice.
Arizona Crater. It was first confirmed by the American engineer and entrepreneur Baringer in 1905 that it was a crater, so the crater is also known as the Bassenger Crater. Not only is it large, but it is also peculiar, making it a great place for local sightseeing.
The crater is about 1,200 meters in diameter, about 180 meters deep, and the edge level is 30 to 40 meters high, which is close to being square. The formation of the Baringa crater is a "large iron block", estimated to be 60 meters in diameter and about 1 million tons in mass, 20,000 years ago at a speed of 20 kilometers per second to hit the earth, resulting in a very large **, thus leaving the earth with an "wound" that is difficult to heal.
Lake Cali on the island of Salemaa, Estonia. At the end of the 20s of the 20th century, it was determined that the lake was a crater with a diameter of 200 meters and a depth of 22 meters. At least six craters were also found within kilometres of the lake.
Salemaa Island is located on the eastern side of the Baltic Sea and covers an area of more than 2,600 square kilometers. It is also rare to have a group of craters on a small island. The meteor shower that caused the crater cluster on the island erupted about 3,500 years ago.
Where there is water, it is the water that has accumulated over time and the terrain has formed.
-
So far, there have been no reports of water being found inside the crater.
-
This is possible, because craters will have these things.
-
This is quite possible, because the contents of the crater have not been thoroughly studied.
-
This should also be possible, because the crater from the meteorite may have water accumulation, and then the weather will be too cold and it will freeze.
-
This is very likely, and if the weather is cold enough, the presence of water and ice is also quite normal.
-
NASA announced on the 13th that its scientists confirmed the presence of water on the moon after a preliminary analysis of the lunar collision data obtained by the lunar crater observation and sensing satellite.
-
I think it's possible, but it's still a bit dangerous to **.
-
In 1991, scientists discovered an unusual bright spot in Mercury's north pole, possibly caused by ice on the surface or underground.
-
I don't know this, there are many mysteries of the universe, and it is worth exploring.

This claim is false because there is no scientific basis for it.

Meteorites are craters because of the ring-shaped craters formed by meteorite impacts on the surface of planets, moons, asteroids, or other celestial bodies. A central cone may form in the center of a crater with a diameter of more than 4 km. The crater may be filled with water due to rainfall and other reasons, forming an impact lake.
On celestial bodies with weathering processes or on celestial bodies with crustal movements, old craters are gradually worn away. For example, on the earth, through weathering, the accumulation of wind-blown dust and sand, and magma impact craters will be covered up or worn away. The formation of known craters on Earth ranges from about 1,000 years ago to 2 billion years ago.
However, craters dating back 200 million years are rarely found, as geological processes have wiped out most of the old craters.

When large meteorites pass through the earth's atmosphere, due to the speed is too fast, friction with the air produces huge heat, in the process of continuous landing, meteorites will continue to disintegrate into fragments, these fragments hit the earth to form craters, these meteorites after long-term weathering after the meteorite slowly decomposes, and finally melts into the ground, so that the shadow of the meteorite can not be seen.
There is also an explanation that it was used by humans around the crater to make iron tools, and archaeologists have found through continuous research that most of the primitive inhabitants living near the crater contain meteorite components in their ** and tools.
Characteristics of meteorites.
The average density of meteorites is between 3 and the main component is silicate. Meteorite has a density of , mainly composed of iron, nickel. The meteorite composition is somewhere in between, with a density in between.
Meteorites vary in shape, the largest meteorite is the Jilin No. 1 meteorite, which weighs 1,770 kilograms, and the largest meteorite is the Goba meteorite from Namibia, which weighs about 60 tons.
More than 40,000 meteorite samples have been collected worldwide, in various styles, which can be broadly divided into three main categories: stony meteorites (the main component is silicate), iron meteorites (iron-nickel alloys) and stony-iron meteorites (a mixture of iron and silicate).

There are two more scientific explanations for the formation of the annular slow lead mountain:
1.Spurt. Soon after the formation of the Moon, the highly hot lava and gas inside the Moon break through the surface layer and eject out, like a volcanic eruption on Earth.
They began to be more powerful, and the lava erupted high and far, piling up on the outside of the vent, forming a crater. Later, the power of the jet gradually decreased, and the jet accumulation only seeped into the bottom of the mountain, forming a small peak, which is the peak in the crater. Some of the injections are extinguished earlier, or there is no re-injection, and there is no ** peak.
2.Meteoroids, meteorite impacts.
A meteoroid hits the moon. On May 13, 1972, a large meteorite crashed into a crater the size of a football field on the surface of the Moon. The moonquake caused by the impact was recorded by a four-moon seismograph placed on the lunar surface.
Proponents of meteorite impacts believe that about 3 billion years ago, there were many meteorites in space, and the moon was in a semi-molten state. When a huge meteorite hits the moon's surface, it splatters rocks and soil around it, forming a circle of craters. And because there is no wind and rain on the surface of the moon and violent geological tectonic activities, the crater formed at the beginning has been preserved.

The fact that there are no meteorites in the crater may be because the meteorites in the crater will slowly decompose after long-term weathering and finally melt into the ground, so the shadow of the meteorite cannot be seen. Or it was used by nearby residents to make iron tools, because archaeologists found through continuous research that most of the original inhabitants living near the crater contained meteorite components in their tools.
Meteorites, also known as "meteorites", are unburned meteors or dust fragments that have left their original orbits outside the Earth and are quickly scattered on the surface of the Earth or other planets.
Most meteorites come from the asteroid belt between Mars and Jupiter, and a small number from the Moon and Mars. Meteorites can be roughly divided into stony meteorites, iron meteorites, and mixed meteorites of stone and iron.
Meteorite refers to the remnants of meteorites that fall to the ground, which are composed of minerals such as iron, nickel, and silicate, also known as meteorite stones, and also refer to meteorites that contain more or all of them are stony.
Craters are mainly formed on the surface of moons or small stars and other celestial bodies after meteorite impacts. Usually they appear to be a ring-shaped, concave-shaped pit. Some craters are particularly large, which are also known as craters. >>>More
The largest crater in the world is Barringer Crater in Arina, USA, North America.
Arizona's incredible crater is an out-of-the-sky meteorite. Arizona Crater, also known as Baringer Crater, is a huge crater in the Arizona Desert with a diameter of kilometers and a depth of 180 meters, which was formed by a meteorite hitting the Earth about 50,000 years ago. The main component of that meteorite is iron, which can be tens of meters wide. >>>More
