Atmospheric Functions and Processes

The video explains Earth's four main components: geosphere, hydrosphere, atmosphere, and biosphere. It details the composition and layers of the atmosphere, highlighting its interactions with other spheres. The atmosphere influences weather, climate, and life by interacting with the geosphere, hydrosphere, and biosphere. These interactions are crucial for maintaining Earth's climate and habitability.

What is the primary gas found in Earth's atmosphere?

• Oxygen

• Nitrogen

• Hydrogen

• Carbon Dioxide

Which layer of the atmosphere is closest to Earth?

• Mesosphere

• Stratosphere

• Exosphere

How do volcanic eruptions affect the atmosphere?

• By absorbing solar radiation

• By increasing oxygen levels

• By releasing gases and particles

• By decreasing nitrogen levels

Which sphere is primarily responsible for weathering and erosion?

• Geosphere
