Intresting facts about Earth
▣ Out of all eight planets in the solar system, the Earth only planet, where life is possible
▣ Earth is the third planet from the Sun in distance and is the largest of the four terrestrial planets as like Mercury, Venus, Earth and Mars.
▣ Earth is the only the place in the Solar System where water exists in all three forms or states - solid, liquid and gas.
▣ The Earth formed about 4.54 billion years ago and scientists estimate that life began about 4.1 billion years ago.
▣ Earth is the only planet with 21% oxygen in its atmosphere and liquid water on its surface.
▣ Earth is the 5th largest planet in our solar system with a radius of 3959 mile or 6334 Kms.
▣ The earth is also referred to as the "blue planet" because from outer space, it appears blue.
▣ The Earth is more than 70% water, but water only comprises less than 1% of the planet's total mass. The Earth's total mass is 5.972 × 10^19 kg.
▣ Earth is the only planet in the Solar System with tectonic plates beneath its surface. These plates are floating on the magma inside the earth, where they occasionally collide with other plates, causing tremors on the surface called earthquakes in everyday language.
▣ Earth's inner space is formed up of around 85- 88 iron and about 47 oxygen in its crust.
▣ All of the planets, except Earth, have been named after Greek and Roman gods and godesses.
▣ Earth has only one natural satellite whose name is Moon, for your information, let us tell you that there are total 67 moons in the planet Jupiter.
▣ The tides in the seas on Earth are brought about by the power of gravity between the Earth and the Moon.
▣ The size of Earth's Moon is about 27% of the size of Earth.
▣ Earth is revolving around the Sun at an average velocity of 107,182 kilometers per hour and we are moving around it with an enormous speed.
▣ The speed of Earth's revolution is continuously dialing back; This intends that in around 140 million years from now, the length of a day on Earth will be 25 hours.
▣ Earth is comprised of four primary layers, to be specific core, outer core, mantle and crust separately.
▣ The temperature of the Earth's inner core is between 5400 and 6000 °C.
▣ Of all of the four layers of the Earth, the thickest layer is metallic, that is 2900 km thick and the thinnest layer is Crust, that's at a median depth of 30 km from the Earth's floor.
▣ Why does Earth have a leap year every four year? Because a year on Earth is approximately 365.2425 days long. However, due to the effects of precession, the length of a year varies between 365.24219 days and 366.24219 days. In order to keep track of these changes, we add one day to our calendar every four years. This means that every four years, we add one day onto the end of February.
▣The changes in the seasons on Earth are due to its rotational motion around the Sun.
▣ The average temperature of the Earth's surface is -88/58 (Min/Max) °C.
▣ The Earth's pivot of revolution is tilted 23.4 degrees with regard to its turn around the Sun and the estimate of the Earth's circle around the Sun is 149,598,262 km.
▣ The coldest permanently inhabited place on Earth: Oymkon, a village in Siberia, Russia, where the temperature reaches -68 ° C in winter.
▣ The hottest day ever on Earth's surface was 56.7 °C (134 °F) °C, recorded on July 10, 1913 at Greenland Ranch, Death Valley, California.
Intresting facts about Earth's atmoshere
▣ The Earth’s Atmosphere is about 480 km thick,which is made of a mixer of sixteen gases: some important as Nitrogen (78.08%), Oxygen (20.94%),Argon (0.934%),Carbon dioxide (0.035%) and many more.
▣ The Earth’s Atmosphere is divided into 5 layers: Troposphere,Stratosphere,Mesosphere,Thermosphere and Exosphere.
▣ Troposphere is the first layer nearest to the Earth’s surface and contain’s half of the Earth’s atmosphere.
▣ Stratosphere is second layer of atmoshpere .Planes fly in Stratosphere to avoid turbulence and cover more distance using less fuel.
▣ Upper part of Stratosphere is known as Ozonoshare is 19-32 km above the Earth’s surface. It absorbs most of the sun’s ultraviolet radiation. An atom of chlorine can destroy more than hundred thousand ozone molecules. Thus Chlorine Affects Ozone layer. The temperatures in the ozone belt are higher than in the troposphere because the ozone absorbs the ultraviolet rays.
▣ Mesosphere is the coolest part of atmosphere with temperature averaging minus 90 degree Celsius.
▣ Temperature of Thermosphere get up to 1500 degree Celsius and space shuttle flew in this layer.
▣ Exosphere is the topmost layer, and widely contains particles of hydrogen and helium.
▣ The barrier between the atmosphere and space is defined as being 100 kilometres above sea level. This boundary is known as Karman line.
▣ Ozonoshare is 19-32 km above the Earth’s surface. It absorbs most of the sun’s ultraviolet radiation. An atom of chlorine can destroy more than hundred thousand ozone molecules. Thus Chlorine Affects Ozone layer. The temperatures in the ozone belt are higher than in the troposphere because the ozone absorbs the ultraviolet rays.
