How did mountains appear?

Because of their gigantic size, people thought that mountains were eternal and unchanging. But geologists, scientists who study mountains, can prove that mountains change and that they are not eternal.

Certain changes in the earth's surface have led to the emergence of mountains that are constantly being destroyed and changed. The slopes of the mountains are destroyed by freezing water, the soil and particles of rocky soil are washed out by rain and water flows. Over time, even the highest peaks turn into hills and plains.

According to the method of education, geologists divided the mountains into four types. However, the mountains were formed as a result of abrupt changes in the earth’s surface many millions of years ago.

Folded mountains are made up of layers of rocks compressed by enormous pressure into gigantic folds. In many places you can see layers of rocks curving like arches and concave lenses. This is the result of compression and pressure of the earth's surface. An example of such mountains are the Appalachians and the Alps.

For vaulted mountains characteristic rocks, raised up in the form of arches. Molten lava, rising under great pressure on the surface of the Earth, was able to lift these layers of rocks. An example of such mountains is the Black Hills in South Dakota in the United States.

The whole mountains arose as a result of faults or failures of the earth's crust. Vast areas of the earth's crust, entire mountain ranges, rose or fell in a short time. The Sierra Nevada mountain range, 740 km long and 150 km wide, located in California, USA, can serve as an example of these mountains.

Volcanic mountains are made up of lava, volcanic ash and cinders that have fallen to the surface of the Earth. Volcanoes are usually conical in shape with a large crater on top. The most famous volcanoes are Rainer, Shasta and Hood in the USA, Fujiyama in Japan, Vesuvius in Italy.

Many mountain systems have been formed by a combination of the above methods. In the Rocky Mountains (USA), you can observe mountain spurs that have arisen as a result of compression, faults and even erosion of lava!

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 ... >>

Impossible engine successfully tested in space 21.12.2016

Chinese scientists managed to successfully test the fuel-free EmDrive engine, the principle of operation of which is still unknown. The apparatus was tested in detail directly on board the Tiangong-2 space laboratory. Now they are going to use it, in particular, on satellites of an orbital nature.

The researchers noted that since 2010, the Chinese government has been funding research on an engine that allegedly can be used to break the inviolable law of conservation of impulse frequencies.

Scientists have built several variations of the device in order to test it in zero gravity. The results of experiments that took into account the influence of various types of factors were able to confirm that EmDrive actually creates a small thrust coefficient.

EmDrive was able to develop a thrust equal to 1,2 millinewtons. The motor is a device that is designed from a magnetron and can generate microwaves by storing vibrational energy.

The unit looks like an overturned bucket. With this design, according to the engineers, it is possible to convert radiation into thrust.
