The deep, cold, and dark zone below the light penetration level, often having low oxygen levels.
The shallow area near the shore where sunlight reaches the bottom, allowing for rooted aquatic plant growth (macrophytes).
Lakes are often temporary features on a geological timescale, created by glacial, tectonic, or volcanic processes, and eventually filled in by sedimentation.
Lakes are complex, dynamic ecosystems that act as critical components of the Earth's hydrological and biogeochemical cycles. As integral parts of the landscape, they store surface water, regulate local climates, and support diverse ecosystems.
