Development Process Cloud formation occurs when water vapor condenses around tiny particles in the atmosphere. Rising air cools to its dew point, causing water molecules to collect on condensation nuclei like dust or salt. Different atmospheric conditions and heights create distinct cloud types, from low-lying stratus to high-altitude cirrus.

Ocean Current Pathways Marine species migrate along ocean currents for feeding, breeding, and seasonal habitat changes. Large oceanic currents create migration highways for species ranging from whales to sea turtles. Temperature gradients and food availability drive timing and routes. Many species navigate using Earth's magnetic field, chemical

Ecological Succession Process Desert-forest transitions occur through ecological succession when environmental conditions change. Initial colonization by drought-resistant plants improves soil conditions by adding organic matter and retaining moisture. Pioneer species create microhabitats that support more diverse vegetation, gradually transform

Atmospheric Circulation Global weather emerges from interactions between Earth's atmospheric circulation cells, jet streams, and surface conditions. Air masses with different temperature and humidity characteristics move across regions, creating weather fronts where they meet. The polar, ferrel, and hadley cells create consistent patterns of air
