The troposphere is the layer of Earth’s atmosphere that is closest to the planet’s surface. It extends from the surface to an average height of about 12 kilometers (7.5 miles). The troposphere is where most of Earth’s weather occurs, including clouds, rain, snow, and wind.
The stratosphere is the layer of Earth’s atmosphere that is directly above the troposphere. It extends from an average height of about 12 kilometers (7.5 miles) to an average height of about 50 kilometers (31 miles). The stratosphere is where the ozone layer is located. The ozone layer absorbs harmful ultraviolet radiation from the sun, which helps to protect life on Earth.
The mesosphere is the layer of Earth’s atmosphere that is directly above the stratosphere. It extends from an average height of about 50 kilometers (31 miles) to an average height of about 85 kilometers (53 miles). The mesosphere is the coldest layer of Earth’s atmosphere, with temperatures reaching as low as -100 degrees Celsius (-148 degrees Fahrenheit).
The thermosphere is the layer of Earth’s atmosphere that is directly above the mesosphere. It extends from an average height of about 85 kilometers (53 miles) to an average height of about 600 kilometers (373 miles). The thermosphere is the hottest layer of Earth’s atmosphere, with temperatures reaching as high as 2,000 degrees Celsius (3,632 degrees Fahrenheit).
Therefore, the correct answer to the question “Which layer is very near to Earth?” is the troposphere.
