What depressions of the World Ocean are among the top ten deepest?

The deepest place on Earth is the Challenger Trench at the southwestern tip of the Mariana Trench in the Pacific Ocean, east of the Mariana Islands. Its depth is 11 meters. If you put Mount Everest (Chomolungma) in this depression, then there will be more than two kilometers of water above its highest peak!

Following the Challenger Basin, the top ten deepest places on the ocean floor include: the Vityaz-Sh Basin (Tonga Trench, Pacific Ocean) - maximum depth 10 meters; the Vityaz basin (Kurilo-Kamchatsky Trench, Pacific Ocean) - 882 meters; Cape Johnson Trench (Philippine Trench, Pacific Ocean) - 10 meters; trough Kermadec (Pacific Ocean) - 542 meters; Nampo depression (Izu-Ogasawara trench, Pacific Ocean) - 10 meters; Milwaukee Trench (Puerto Rico Trench, Atlantic Ocean) - 497 meters; the Argo depression (Northern New Hebrides Trench, Pacific Ocean) - 10 meters; Planet Trench (New British Trench, Pacific Ocean) - 047 meters; Meteor Basin (South Sandwich Trench, Atlantic Ocean) - 9984 meters.

Random interesting fact from the Great Encyclopedia:

What is saliva?

Imagine that you have to eat a lemon. Think about how sour it is. Do you feel saliva start to come out? This is one of the features of our salivary glands. They do not act mechanically, but are controlled by the brain.

There are three pairs of salivary glands. One of them is at the level of the ears, one under the tongue, one under the lower jaw. The salivary glands solve the immediate problem of automatically regulating the quantity and quality of saliva. Animals have a small amount of saliva, as they eat raw food.

Salivary glands do not exist in fish, but they are highly developed in grain-eating birds. When a cow chews food, her salivary glands secrete about 50 liters of saliva. If she eats dry hay, the amount of saliva produced increases to 190 liters. And the largest amount of saliva that a person's salivary glands can secrete in a lifetime is 23 liters! Each of the salivary glands performs a specific function.

The largest gland - parotid - determines the water content of saliva. The main purpose of saliva is to moisten chewed food. The submandibular gland produces saliva of various kinds, which makes food "slippery". What kind of food we eat determines which salivary glands will produce more saliva.

If we taste a juicy apple that does not need to be moistened, the submandibular gland functions. But if we eat dry cookies, the parotid gland begins to work and produces a large amount of liquid saliva. Human saliva contains an enzyme called amylase. Amylase breaks down starch molecules into dextrin and then into glucose.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Film and the composition of the air of the auditorium 26.05.2016

Scientists analyzed air samples from cinema halls that showed films of various genres, and found that the emotional state of the audience can be determined by the composition of the gases exhaled by it.

Feedback also works: you can determine the film by the dynamics of the composition of the atmosphere in the cinema. Scary and funny scenes are best defined, say chemists from the Max Planck Institute for Chemistry and the Gutenberg University of Mainz.

While watching The Hunger Games, according to Jonathan Williams, head of the research team at the Max Planck Institute for Chemistry, the levels of carbon dioxide and isoprene in the air rose sharply as soon as the heroine began to fight for her life on the screen.

A healthy person exhales carbon dioxide mixed with small amounts of other gases - their number reaches 800. The physiological processes that determine the synthesis and release of these substances have not yet been fully studied.

Initially, researchers dealt with the issue of gases exhaled by humans and their impact on the composition of the planet's atmosphere and the greenhouse effect. The study of the atmosphere over the football stadium during the match did not give interesting results - perhaps because the match ended with a score of 0 - 0. Then the scientists came up with the idea to analyze the air in rooms where people experience strong emotions - for example, in the cinema.
