Study Notes
Oceans
- Oceans cover 71% of the Earth's surface
- Oceans can be divided into five major areas: Arctic, Atlantic, Pacific, Indian, and Southern Oceans
- Oceans host almost 98% of the Earth's water
- Aquatic life zones are divided into saltwater (marine) and freshwater
Marine Aquatic Systems
- Marine aquatic systems include oceans, bays, estuaries, coastal wetlands, shorelines, coral reefs, and mangrove forests
- The open sea is divided into three vertical zones: euphotic, bathyal, and abyssal
- The euphotic zone is the brightly lit upper zone where photosynthesis occurs
- The bathyal zone is the dimly lit middle zone with little sunlight and no photosynthesis
- The abyssal zone is the deepest, dark, and cold zone with no sunlight and low oxygen levels
- Marine snow, composed of dead and decaying organisms, provides food for deep-sea organisms
Human Impacts on Marine Aquatic Systems
- Human activities are disrupting and degrading marine ecosystems, particularly coastal marshes, shorelines, mangrove forests, and coral reefs.
Freshwater Systems
- Freshwater systems include lakes, rivers, streams, and inland wetlands
- Human activities are disrupting and degrading freshwater ecosystems.
Climate Change
- Climate change refers to significant changes in climate over a continuous period
- Climate change can be caused by natural processes, external forces, and human activities
- Volcanic eruptions are a natural cause of climate change, releasing aerosols like carbon dioxide, sulfur dioxides, and volcanic ash
- Human activities contribute to climate change through fossil fuel burning and industrial processes, increasing aerosols in the atmosphere
Effects of Climate Change on Society
- Climate change can lead to increased deaths from malnutrition and heat stress
- Vector-borne diseases like malaria and dengue fever could become more widespread
- Rising sea levels will cause more flooded areas and coastal protection risks
The Hydrologic Cycle
- The hydrologic cycle is the continuous recycling process of water
- Evaporation is the process of water changing from liquid to gas, driven by solar energy
- Condensation is the opposite process of water changing from gas to liquid
- Evapotranspiration is the process of water evaporating from plants, including both rainfall and water taken up from the soil
- Precipitation occurs when water vapor in the atmosphere cools and forms droplets
- Runoff is surface water flowing downhill into streams and rivers
- Groundwater is water that seeps into the soil and fills spaces in the subsurface
- Aquifers are porous layers of rock saturated with groundwater
