ilmaekosysteemi

Ilmaekosysteemi refers to the atmospheric system and its interactions with living organisms and the Earth's surface. It encompasses the various layers of the atmosphere, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, and the physical processes occurring within them. These processes include weather patterns, climate, atmospheric circulation, and the composition of the atmosphere.

Living organisms, from microscopic airborne bacteria and fungi to larger animals and plants, are an integral part of the ilmaekosysteemi. They influence atmospheric composition through respiration, photosynthesis, and decomposition. Conversely, the atmosphere provides essential elements for life, such as oxygen and carbon dioxide, and shields organisms from harmful solar radiation. The exchange of gases and particles between the atmosphere and the biosphere is a critical component of this ecosystem.

The ilmaekosysteemi also interacts with other Earth systems, namely the hydrosphere (water), lithosphere (land), and cryosphere (ice). Evaporation from oceans and lakes contributes to atmospheric moisture, influencing precipitation. Volcanic activity releases gases and ash into the atmosphere, impacting air quality and climate. The circulation of air masses also plays a significant role in distributing heat and moisture across the globe, shaping regional climates and ecosystems. Understanding the ilmaekosysteemi is crucial for comprehending global climate change, air pollution, and the delicate balance of Earth's life-support systems.
