Detailed explanation-1: -Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere . Troposphere.

Detailed explanation-2: -While more than 6, 000 miles thick, the atmosphere is comprised of five distinct layers. Each layer has unique characteristics. In between these layers are boundaries called “pauses, ” where changes in temperature, chemical composition and density are the greatest.

Detailed explanation-3: -These primary layers are the troposphere, stratosphere, mesosphere, and thermosphere. A further region at about 500 km above the Earth’s surface is known as the exosphere. Complete answer: The Earth’s atmosphere has four primary layers: the troposphere, stratosphere, mesosphere, and thermosphere.

Detailed explanation-4: -The ozone layer which protects us from harmful UV rays is present in the stratosphere.

Detailed explanation-5: -Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in atmospheric layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
