Detailed explanation-1: -The troposphere also contains water in all three phases (liquid, solid, and gas) as well as solid particles called aerosols. The dry composition of the atmosphere is mostly nitrogen and oxygen.

Detailed explanation-2: -The atmosphere-a mix of gases, mostly nitrogen and oxygen along with less abundant gases like water vapor, ozone, carbon dioxide, and argon-is also essential to life in the biosphere.

Detailed explanation-3: -A subsystem is a single, predefined operating environment through which the system coordinates the work flow and resource use. The system can contain several subsystems, all operating independently of each other. Subsystems manage resources. All jobs, with the exception of system jobs, run within subsystems.

Detailed explanation-4: -Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Detailed explanation-5: -Atmosphere. The Earth’s atmosphere is the gaseous layer that envelopes the world.
