Facts About Earth

DiD U Know! Planet  EARTH. The only cosmic object known to contain life is Earth, which is located third from the Sun. Although the Solar System contains enormous amounts of water, only Earth has liquid surface water. The oceans cover around 71% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Land, made up of continents and islands, makes up the remaining 29% of the Earth's surface. Mountain ranges, volcanoes, and earthquakes are all results of the interaction between the tectonic plates that make up the Earth's surface layer. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet. In this article I will give you amazing information about Earth. So let’s start:

Size:

• With an average diameter of 12,742 kilometers (7,918 mi), Earth has a roughly spherical form, ranking fifth among the Solar System's planetary-sized objects and largest among its terrestrial objects.
• The diameter of the Earth is 43 kilometers (27 mi) bigger at the equator than at the poles as a result of the rotation of the planet, which causes its shape to bulge around the Equator and gradually flatten in the poles. Therefore, an oblate spheroid is a better description of the shape of Earth.
• Local topography changes are another aspect of Earth's shape. Although the largest differences, such as the Mariana Trench (10,925 meters or 35,843 feet below local sea level) and Mount Everest (8,848 meters or 29,029 feet above local sea level), very slightly alter the average radius of the Earth (by 0.17% and 0.19%, respectively).

Atmosphere:

• Atmospheric pressure at sea level on Earth typically ranges between 101.325 kPa (14.696 psi) and 8.5 km (5.3 mi).
• 78.084% of a dry atmosphere is nitrogen, 20.946% is oxygen, 0.934% is argon, and there are very small quantities of carbon dioxide and other gaseous molecules as well.
• The typical water vapour level is roughly 1%, although it can range from 0.01% to 4%.
• Over the oceans compared to land, clouds cover around two thirds of the Earth's surface.
• With considerable change due to weather and seasonal variables, the height of the troposphere varies with latitude, ranging from 8 km (5 mi) in the poles to 17 km (11 mi) near the equator.
• N2 and O2 make up the majority of the Earth's atmosphere.
• Carbon dioxide (CO2) and other greenhouse gases in the atmosphere trap solar energy near to the surface.
• The atmosphere contains large amounts of water vapour, which creates the majority of the planet's clouds.
• Tropical regions receive more solar energy than polar ones, and air and ocean circulation redistributes it.
• The climate of an area is affected by latitude, elevation, and the presence of seas that act as climate regulators. Most places have extreme weather, which has a significant influence on living.
•  Examples include tropical cyclones, thunderstorms, and heatwaves.

COMPOSITION:

• The mass of the Earth is around 5.97 1024 kg (5,970 Yg).
• Iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulphur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%) make up the majority of its composition.
• Trace quantities of other elements make up the remaining 1.2%. The core area is thought to be predominantly made of iron (88.8%) as a result of mass segregation, with minor quantities of nickel (5.8%), sulphur (4.5%), and fewer than 1% trace elements.
• Nearly all of the rocks that make up the crust are oxides; the notable exceptions to this rule are chlorine, sulphur, and fluorine, whose combined amounts in most rocks are typically much less than 1%.
• 11 oxides, namely silica, alumina, iron oxides, lime, magnesia, potash, and soda, make up more than 99% of the crust.

Life:

• Only the planet Earth is known to be habitable and to have supported life. About 100 million years after Earth's formation, life on Earth began to emerge in its earliest reservoirs of water.
• Earth's life has been influencing and residing in a variety of distinct ecosystems, and it has finally spread globally to form an overall biosphere. Thus, over a long length of time, life has had an influence on Earth, dramatically changing both its surface and atmosphere, leading to events like the Great Oxidation Event.
• The diversity of life on Earth over time has allowed the biosphere to have many biomes, each of which is home to a group of somewhat similar plants and animals. The many biomes grow at various altitudes, water depths, planetary temperature latitudes, and on land with various humidity levels.
  
  
  

Unbelievable Facts:

• The Earth's rotation is steadily slowing down:

Even though the rate of acceleration is not uniform, it is occuring at an almost imperceptible pace of 17 milliseconds per hundred years. While this lengthens our days, it does so so gradually that it would take up to 140 million years for a day to reach its current length of 25 hours.

• The Earth was previously thought to be the centre of the cosmos:

Ancient astronomers maintained that the Earth was stationary and that other celestial bodies were in circular orbits around it despite the Sun and planets appearing to move in proportion to their point of view.

• There is a strong magnetic field on Earth:

The planet's nickel-iron core and quick rotation together are what generate this phenomena. The Earth is shielded from the impacts of solar wind by this field.

• The Earth's natural satellite:

The Moon is the biggest and massive satellite of any planet in our solar system when compared to the size of the body it orbits. It is actually just the seventh largest natural satellite in terms of size.

• Earth's form is affected by melting glaciers:

The melting of glaciers, a consequence of climate change, may be the cause of that "spare tyre" encircling Earth, or as some scientists refer to it, the "waistline."

• Asia is home to 60% of the world's population:

It's not difficult to comprehend that 60 percent of the world's population resides in Asia, which is home to more than 40 nations, some of which are among the most populous nations ever.
