Study Notes
Water and Water Cycle
-
States of Water: Water exists as a solid (ice), liquid (water), and gas (water vapor).
-
Water Stores: Water is stored in various locations including glaciers, groundwater, lakes, and oceans.
-
Hydrologic Cycle: The continuous movement of water through the environment, including precipitation, groundwater flow, surface runoff, evaporation, and transpiration. Condensation is also part of this cycle.
-
Water Budget: The balance between water inputs (e.g., precipitation) and outputs (e.g., evaporation/transpiration) determines if there's a surplus or deficit. A surplus occurs when inputs exceed outputs, and a deficit when outputs exceed inputs.
Water Issues
-
Floods: Result from the overflow of large bodies of water.
-
Droughts: Occur when an area receives very little rain over an extended period of time.
Water Use
-
Agriculture: Uses the most significant amount of water.
-
Industry: Uses water for cooling machinery.
-
Domestic: Uses water for tasks like showering and laundry.
-
Recreation: Uses water for activities like water sports (least used).
Tropical Rainforest (TRF)
-
Location: Primarily near the equator.
-
Characteristics: Evergreen forest with distinct layers (emergent, canopy, undergrowth).
-
Adaptations: Drip tips, broad leaves, waxy leaves, and buttress roots (to cope with high rainfall and humidity).
Mangroves
-
Location: Coastal areas, often in sheltered environments.
-
Characteristics: Lower plant diversity compared to TRFs, with horizontal layers.
-
Adaptations: Salt-secreting leaves, aerial roots, and salt-extruding root systems, allowing these trees to survive in saline conditions/water.
Forest Uses
-
Habitation: Forests provide places for people to live.
-
Food: Forests are a source of food.
-
Raw Materials: Forests provide raw materials for various products.
-
Recreation: Forests offer opportunities for recreation.
Forest Impacts/Management
-
Deforestation: The removal of trees from forests.
-
Greenhouse Effect: Activities that lead increased levels of greenhouse gases in the atmosphere.
-
Sustainable Management: Practices like rehabilitating disturbed areas, promoting education, regulating forestry activities, and establishing protected areas can help maintain forests sustainably.
