SOLAR SYSTEM

Detailed explanation-1: -From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere . Troposphere. Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth’s poles and higher at the equator.

Detailed explanation-2: -The region above the stratosphere is called the mesosphere. Here the temperature again decreases with height, reaching a minimum of about-90°C at the “mesopause".

Detailed explanation-3: -The layer immediately above the troposphere is called the stratosphere. The boundary between the troposphere and the stratosphere is called the “tropopause".

Detailed explanation-4: -Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Detailed explanation-5: -Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The transition boundary which separates the mesosphere from the stratosphere is called the stratopause.

Detailed explanation-6: -It protects the earth’s surface from harmful radiation from the sun. Without the atmosphere, there could be no life on earth. The atmosphere is mainly composed of five layers: These are troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Detailed explanation-7: -Exosphere: 700 to 10, 000 km (440 to 6, 200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles) Troposphere: 0 to 12 km (0 to 7 miles)
