Hi, Guys…

Welcome back our new blog ‘THE EARTH’ . 

Earth is located three planets away from the Sun. The fact that Earth is an ocean world—the only one in the Solar System to support liquid surface water—makes this possible.
The dynamic atmosphere of Earth keeps the planet's surface conditions stable and shields it from most meteoroids and ultraviolet rays upon entry. Its main constituents are oxygen and nitrogen. The atmosphere contains a large amount of water vapor, which forms clouds that cover most of the earth. As a greenhouse gas, water vapor works with other greenhouse gases in the atmosphere, especially carbon dioxide (CO2), to produce the ideal environment for the persistence of both liquid surface water and water vapor through their ability to absorb solar radiation. The average surface temperature of 14.76 °C , at which water is liquid at standard atmospheric pressure, is maintained by this mechanism. Geographical differences in the amount of energy absorbed—for example, the equatorial region receiving more sunlight than the polar regions—drive atmospheric and ocean currents, resulting in a global climate system with distinct climate regions. These variations also produce a variety of weather phenomena, including precipitation, which facilitates the cycling of elements like nitrogen.
The circumference of the ellipsoid that is Earth is approximately 40,000 km. It is the Solar System's densest planet. It is the biggest and most massive of the four rocky planets. The Earth orbits the Sun at a speed of eight light-minutes, taking 365.25 days to complete one revolution. It takes Earth slightly less than a day (approximately 23 hours and 56 minutes) to complete one full rotation on its axis. Seasons are created by the tilt of Earth's rotational axis with regard to the perpendicular to its orbital plane around the Sun. The Moon, the only permanent natural satellite of Earth, circles the planet at a speed of 384,400 km (1.28 light seconds) and has a width of around 25% of Earth's surface.
Earth evolved from gas and dust in the early Solar System 4.5 billion years ago, just like the majority of other worlds in the Solar System. The ocean created throughout the first billion years of Earth's existence, and life eventually emerged within it. The Great Oxidation Event occurred two billion years ago as a result of life spreading throughout the planet and changing its surface and atmosphere. From its origin in Africa 300,000 years ago, humans have expanded to every continent on Earth. The biosphere and Earth's natural resources are essential to human survival, yet environmental effects from human activity are growing. The way that humans and many other forms of life currently live on Earth is threatened by the unsustainable impact that humanity is having on the climate and biosphere, which is also leading to widespread extinctions.
