GEOG 1114 1st Edition Lecture 17Outline of Last Lecture Measuring climates according to climate controls -Circulation patterns-Air masses -Ocean currents -LocationClassifying Climates Climatic Zones Climographs Major Climate types: their groupings Outline of Current Lecture -Characteristics of water -Global water storage -Uneven distribution Current Lecture Characteristics of Water Finite Resource – Unique Characteristics-Liquidity/ only substance to found in all three states of matter.-High Heat Capacity-Expands as it coolsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-Capillarity-Universal Solvent-Dissolves almost all substances, moves/recycles nutrients, picks up, moves and dissolves -Fluvial processes – shapes earth’s crust –erosion, weathering landform-Ecosystem services / Essential for life Water Planet -- Finite Resource97.2 Oceans, 2.0 Glacial, 0.5 groundwater, .25 Surface water, .04 Soil moisture, .001 atmospheresGlobal Water Storage: has an uneven distributionOceans- 97.20%Glaciers 2.00Groundwater 0.50Surface water 0.25Soil moisture 0.04Atmosphere 0.0001 StorageOceans - 97.2%Distribution: Vast majority of surface is oceans (76%) - 5 oceans - Smaller bodies- seas, gulfs, and bays, estuaries (where salt and fresh water meet)Characteristics of Ocean Water:Chemical Composition- Contains dissolved minerals -Sodium and chlorine- Salinity -During evaporation, desalinization occurs -Increasing acidity- Carbon dioxide absorbed by ocean water creates carbonTemperature-Decreases with increasing latitude- ranges 28-80 degrees F Density- high temperature means low density High salinity means high density Movement- Tides, Currents, wavesTides- vertical bulges -Gravitational attraction of Moon (lunar tides) and Sun (solar tide) -Two bulges form on opposite sides of planet -Two tidal cycles in 24 hours -Flood tide & Ebb tide -Monthly tidal range- due to position of earth’s moon and sun Waves: -Disturbances to the sea surface- movement of energy -Wind -Little Forward progress is observed -Wave breaking can result in shifting of waterIce Sheets and Glaciers (Cryosphere) – 2% -Second greatest storage of the Earth’s water -Two groups, ice on land/ice in water-Fresh Water -Approximately 10% of the Earth’s surface is ice Groundwater - .5% -Water beneath land surface worldwide -Precipitation or water basins are the sources -Quantity held depended on –Porosity –Permeability -Aquifers and
