Study Notes
Water Cycle
- Water and chemical elements are recycled through biogeochemical cycles involving biotic (living) and abiotic (non-living) factors.
- Water can be old, with some molecules existing for millions of years, continuously moving through the cycle.
- Water exists in three states: gas (vapor), liquid, and solid (ice), undergoing various processes to change states.
Water State Changes
- Evaporation: Water transforms from liquid to vapor due to heat from the sun.
- Sublimation: Ice and snow convert directly to vapor also driven by solar heat.
- Transpiration: Plants release vapor through stomata, contributing to evapotranspiration alongside evaporation from the land.
- Condensation: Water vapor cools, forming droplets that may create clouds. Larger droplets eventually fall as precipitation.
- Precipitation Types: Includes rain, snow, sleet, and hail.
Water Flow and Storage
- Runoff: Water that flows over land after precipitation, eventually entering bodies of water.
- Infiltration: Water that soaks into the ground, becoming groundwater.
- Aquifers: Underground layers that store water, potentially for thousands of years.
- Ice masses and glaciers can store frozen water for prolonged periods.
Carbon Cycle
- Carbon is recycled through different processes involving living organisms and the atmosphere, essential for the creation of organic compounds.
- Major carbon reservoirs include the atmosphere, ocean, sedimentary rocks, and fossil fuels.
- Carbon exists in various forms: carbon dioxide (CO2), carbonic acid (H2CO3), bicarbonate ions, organic compounds, and other carbon-based substances.
Carbon Exchange Processes
- Carbon dioxide is released through cellular respiration in organisms and decomposition of organic material.
- Photosynthesis removes carbon dioxide from the atmosphere, converting it into organic compounds.
- Human activities, such as burning fossil fuels and deforestation, significantly increase atmospheric carbon dioxide levels.
- Geological processes like sedimentation slowly cycle carbon, storing it in rocks for millions of years.
Human Impact on Carbon Cycle
- Increased carbon dioxide concentrations today are higher than in the past hundreds of thousands of years, largely due to industrial activities.
- Land clearing reduces autotrophs that absorb CO2, while burning land also releases previously stored carbon.
