Humans rely primarily on vision to identify the direction of terrain. The sun's rays can no longer reach the depth of 6,000 meters in the ocean. It's impossible to determine direction if you can't see your planet. fingers. No one has ever tried to stay at such a depth without navigation. In this place, no one should be able to do that.
The human senses are primarily composed of three systems: touch, vision, and hearing. Touch mainly involves touching the surface features of objects. In the ocean there is water in all directions, so touch is no different. ; hearing can identify directions, but generally Only when the background sound interference is low and there is another loud sound source can you use the sound source to identify the direction of the sound source. There are manyits complex sound sources in the ocean, and it is impossible to locate the sound source without a clear sound source. Visual positioning is simpler, just look at the direction of an object's shadow in the sun, the position of the sun in the sky, etc. At night you can use the Big Dipper, Polaris, Morning Star, etc. to locate. In the sea 6,000 meters deep, you can't even see your fingers. Are there any obvious signs in there?
Ocean currents in a certain area will have a certain direction, and deep sea water also flows. To identify the direction based on ocean currents, you need to explore all the hydrological features in advance and memorize them. your mind. When pilots and astronauts train, they have to go through a lot of training to position themselves on the sea, but maybe no one can see the sky. can achieve positioningnt relying solely on the water flow. Putting aside the hypothetical situation, people have to take a deep-sea submersible to reach a depth of 6,000 meters. Manned submersibles are equipped with navigation and positioning equipment, so they generally will not get lost, and for safety reasons, there may be bands. Hanging on submersibles, the rope can also prevent the submersible from being lost.
Human beings do not have the ability to rely on the Earth's magnetic field to discern direction, so it is impossible for humans to swim freely in the ocean like whales. Therefore, regardless of the fact that the sea water pressure can crush people to death, it is difficult for people to discern the direction in the 6,000 meter deep sea, and the final result is to be buried in the belly of a fish.
Also called Venus:
Vénus is the second planet after the sun and the brightest star in the sky. At its maximum brightness, it has a magnitude of -4.4. is brighter than the famous Sirius is 14 times brighter. Venus is an inner galaxy, so it is sometimes a morning star and sometimes an evening star. No satellite of Venus has yet been discovered. Because Venus and Earth are very similar in size, mass, density, and weight, and because they formed at almost the same time from the same nebula, astrologers consider them sister planets. However, not long ago, scientists discovered that Venus is actually very different from Earth. There is no ocean on Venus. It is surrounded by a thick atmosphere composed mainly of carbon dioxide and contains no water. Its clouds are composed of tiny droplets of sulfuric acid. At the surface, its atmospheric pressure is equivalent to 92 times thatthe sea level on Earth.
Because Venus appears in the sky in the morning and dusk respectively, the ancient Chinese called it Taibai or Taibai Venus. Chinese history books call the morning star “Qiming” and the evening star “Chang Geng”. Ancient astrologers always believed that there were two such planets, which is why they called them "Morning Star" and "Evening Star" respectively. In English, Venus - "Venus" (Venus) is the ancient Roman god of love and beauty. It was shrouded in mystery by rolling clouds.
Due to the "greenhouse effect" caused by Venus' thick carbon dioxide atmosphere, the temperature on Venus' surface reaches around 482°C. Sunlight passes through the atmosphere and warms the surface of Venus. Heat on the Earth's surface is blocked by the atmosphere as it radiates outward and cannot be dissipated into space. Thatmakes Venus hotter than Mercury. One day on Venus is equivalent to 243 Earth days, which is longer than its year of 225 days. Venus rotates from east to west, meaning that on Venus the sun rises in the west and sets in the east.
The surface of Venus is dotted with numerous small craters. Due to Venus' thick atmosphere, craters less than 2 kilometers in diameter are almost impossible to preserve. And when large meteorites hit the surface of Venus before small craters formed, the fragments they produced created exceptional groups of craters on the surface. Volcanoes and volcanic activity are numerous on the surface of Venus. At least 85% of Venus' surface is covered in volcanic rock. Large quantities of lava flowed hundreds of kilometers, filling the lowlands and forming vast plains. In addition to hundreds of large volcanoes, more than 100,000 small craters pdot the surface of Venus. Lava flows from volcanoes create long channels that can stretch hundreds of miles, with one stretching more than 7,000 miles.
