  2. Source–sink dynamics - Wikipedia

    en.wikipedia.org/wiki/Source–sink_dynamics

    Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population.

  3. Drainage basin - Wikipedia

    en.wikipedia.org/wiki/Drainage_basin

    For example, rainfall on roofs, pavements, and roads will be collected by rivers with almost no absorption into the groundwater. A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean.

  4. Depression (geology) - Wikipedia

    en.wikipedia.org/wiki/Depression_(geology)

    Sink: an endorheic depression generally containing a persistent or intermittent (seasonal) lake, a salt flat (playa) or dry lake, or an ephemeral lake. Panhole: a shallow depression or basin eroded into flat or gently sloping, cohesive rock. [2] Collapse-related: Sinkhole: a depression formed as a result of the collapse of rocks lying above a ...

  5. Deposition (geology) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(geology)

    For example, chalk is made up partly of the microscopic calcium carbonate skeletons of marine plankton, the deposition of which induced chemical processes to deposit further calcium carbonate. Similarly, the formation of coal begins with the deposition of organic material, mainly from plants, in anaerobic conditions.

  6. Ecology - Wikipedia

    en.wikipedia.org/wiki/Ecology

    The ecology of metapopulations is a dynamic process of extinction and colonization. Small patches of lower quality (i.e., sinks) are maintained or rescued by a seasonal influx of new immigrants. A dynamic metapopulation structure evolves from year to year, where some patches are sinks in dry years and are sources when conditions are more favorable.

  7. Sedimentary basin - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_basin

    An example is the San Bernardino Mountains north of Los Angeles, which result from convergence along a curve in the San Andreas Fault system. The Northridge earthquake was caused by vertical movement along local thrust and reverse faults "bunching up" against the bend in the otherwise strike-slip fault environment.

    As Leon County watches and waits to see if recent rains keep the lake filled, here's the scientists' answers to 15 questions about the dry-down and common misconceptions.

  9. Endorheic lake - Wikipedia

    en.wikipedia.org/wiki/Endorheic_lake

    Depending on water losses, precipitation, and inflow (e.g., a spring, a tributary, or flooding), the temporal result of a lake in a sink may change. The lake could be a persistent lake, an intermittent lake, a playa lake (temporarily covered with water), or an ephemeral lake, which completely disappears (e. g. by evaporation) before reappearing in wetter seasons.
