Researchers have long known that the average temperature on earth varies according to the cosmic rays of the sun, probably because solar activity influences cloud formation in the atmosphere. This is now confirmed by an experiment from CERN, the European research center for particle physics in Switzerland.
According to the latest figures, around 7500 tonnes of scrap are flying around the earth. It concerns almost 30,000 objects larger than 10 centimeters, 750,000 pieces of 1-10 centimeters cm and 166 million of 0.1-1 centimeters. The many scrap pieces come from sophisticated satellites and remnants of rocket engines. With speeds up to 28.
That the sky is blue has to do with the spread of light. The light with the shortest wavelengths is spread farther to the surface of the earth. The blue light is the color in the visible spectrum with the shortest wavelength, and therefore much more blue light is spread over the sky than all other colors.
Water consists of oxygen and hydrogen. The universe has a lot of hydrogen, but there is a limited amount of oxygen and it only originates in large stars. The element is spread through space through star explosions (novas and supernovas). Our solar system was created because a supernova swung a cloud of material in all directions.
After new geological research, the water figure on earth seems to be incorrect. The water on our planet is part of various cycles, the most famous of which is between the oceans and the atmosphere. However, there is also a cycle in which water from the oceans is drawn deep into the earth's crust and mantle when the tectonic plates dive below each other.
Calculations show that the very young earth was about 1000 ° C hot about 4.6 billion years ago. The components of the earth melted, partly due to the heat of the decay of radioactive elements. Iron and a number of other elements moved to the center of the earth, where the iron slowly solidified to the central core.
We do not know exactly how our atmosphere was created, but we do know that its composition has changed considerably since our planet emerged from a cloud of gas and dust around the young sun some 4.6 billion years ago. What is the atmosphere? The atmosphere is the layer of air that surrounds the earth. The chemical processes in the atmosphere have an impact on life on earth.
What is the ozone layer? The atmosphere of the earth consists of a number of gases, one of which is ozone. By the ozone layer we mean the layer in the atmosphere that consists of ozone and protects the earth as a shield against the dangerous ultraviolet rays of the sun. The earth's atmosphere or atmosphere consists of four layers: the troposphere, stratosphere, mesosphere and thermosphere.
Although scientists have proven for 2,000 years that our planet is ball round, there is still a group of fanatics who claim that the earth is flat. However, it takes no more than common sense to confirm that the earth is round. Here are five tangible proofs. PROOF 1: Earth casts a round shadow on the moon More than 2000 years ago, Aristotle discovered one of the most tangible proofs that our planet is spherical.
You would not immediately think that the other planets in our solar system are important for the Earth. We revolve around the sun, which energizes life on our planet. The structure of the solar system and the location of the other planets have, however, been decisive for the development of life on earth.
The earth is four times as big as the moon. If you look at the earth from the moon, it seems four times as big as the moon from the earth. But it is not always experienced according to the stories of the astronauts who have been on the moon. The first man on the moon, Neil Armstrong, put it as follows: "I suddenly realized that this little beautiful, blue" pea "was the earth.
The blue is not the color of the sky that we see, but one color from the light of the sun that is scattered by molecules in the atmosphere. Sunlight contains all colors and therefore looks white. But when the sunlight moves through the Earth's atmosphere, it collides with the oxygen and nitrogen molecules that break up the light.
Mercator turned the round globe into a rectangle on his maps. This means that compass directions are always straight lines, but the land masses did not always get the right surface. Now researchers from Australia and the US have made a world map with the title Equal Earth, on which continents have the correct mutual size, according to the method of pseudocilindrical map projection.
The total amount of water has been changing since the earth came into existence and that is still the case today. However, the fluctuations have decreased. The water forms a cycle in which it constantly changes between reservoirs: rivers, lakes, seas, the atmosphere, glaciers and groundwater. Along the way it changes state - solid, liquid and gaseous - but that does not affect the total amount of water.
The earth's core consists of a fixed inner part and a liquid outer part. The core determines the magnetic field and therefore life. But how does that core get there? The prevailing views Through seismic data, chemical theories and measurements of the earth's magnetic field, researchers know that the core makes up about half the diameter of the earth and consists mainly of iron and nickel.
Researchers use radiometric methods to date rocks from the time of the earth's inception. Radioactive variants of elements (isotopes) have different half-lives, and they can use them. By comparing the amount of the original isotope with expired products, one can determine how much time has elapsed.
The distribution of land on earth is caused by plate tectonics, or movements in the upper layer of the earth. Plate tectonics is one of the most important forces behind the heat flows in the earth, causing the large continental plates to slide among themselves. However, there is no indication whatsoever that plate tectonics would "advance" a particular hemisphere.
NASA astrophysicists have discovered that the Earth is in a bubble that can protect us from radiation in the days following a solar storm. That bell was detected in 2014, but only now does data from NASA's two Van Allen probes show that people have created that bell. Deadly electrons destroy electronics Spacecraft, satellites and probes around the earth are protected from radiation by the earth's magnetic field.
A globe without people would largely look like the African national parks with their rich animal life. This is the conclusion of a study in which scientists from Aarhus University in Denmark simulated for the first time how mammals would have been distributed around the world if man had not existed.
Although zodiacal light looks like a sunset, the spectacular phenomenon only comes about two hours after sunset, around 10 pm, when the twilight has disappeared. Then you see a conical haze, which is crooked on the horizon on the west. The light comes from an enormous disk of dust from, among other things, comets around the sun, which reflect sunlight back to the earth.
Have you ever wondered where you end up when you dig a tunnel through the earth? With this interactive map you will find out wherever you are in the world. For example, if you dig straight down from Amsterdam, Copenhagen or Cologne, you will reappear in the Pacific Ocean near New Zealand.
