Geosphere

The layer of gas surrounding Earth plays a crucial role in protecting life on the planet. This is where all weather phenomena occur, and it serves as a shield while protecting us from harmful radiation. Discover how changes in the atmosphere impact our daily lives and the rest of Earth's systems.

Basic Ingredients

The atmosphere consists of nitrogen (78%), oxygen (21%), and other gases (1%) including carbon dioxide, argon, and water vapor.

Layers

The atmosphere is divided into layers, extending from the troposphere, which contains most of the weather, to the exosphere, which reaches into outer space.

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere
• Exosphere

Effects and Interactions

• Weather and climate: The atmosphere regulates weather and climate, including wind, precipitation, and temperature.
• Protecting Earth: The atmosphere acts as a natural shield against harmful ultraviolet radiation and small meteoroids.
• Current challenges: Climate change, increased levels of carbon dioxide and greenhouse gases causing global temperatures to rise.
• Air pollution: Air pollution negatively affects the health of humans and other living organisms.
