Which ecological system includes the air and weather?

• A. Biosphere
• B. Geosphere
• C. Atmosphere
• D. Hydrosphere

Answer: (C)

The atmosphere is the ecological system that includes air and weather. It’s the gaseous envelope that surrounds Earth, made up mainly of nitrogen and oxygen with water vapor and other gases. Weather refers to the short-term conditions within this gaseous layer—temperature, humidity, wind, clouds, and precipitation—driven by energy from the sun and how it moves through the air. This atmosphere not only contains the air we breathe but also exchanges energy and moisture with the rest of Earth’s systems, influencing climate, life, and many surface processes. In contrast, the hydrosphere covers all water, the geosphere includes rocks and landforms, and the biosphere encompasses living organisms.
