Study Notes
Water Types
- Salt water: High salt content, primarily found in oceans.
- Fresh water: Low dissolved salt content, sourced from lakes, rivers, ponds, and wells.
Water Movement and Quality
- Water cycle: Continuous movement of water between oceans, land, and atmosphere.
- Water quantity: Refers to the overall amount of water present in a given area.
- Water quality: Determines suitability for use based on various characteristics.
Glaciers and Ice Formations
- Glacier: Large mass of moving compressed snow and ice.
- Ice cap: Dome-shaped glacier covering substantial land areas, flowing outward.
- Ice field: An area that supplies multiple glaciers.
Types of Glaciers
- Valley glacier: Located between mountain ranges.
- Continental glacier: Thick ice sheet covering a continent.
Glacier Dynamics
- Ice fall: A glacier flow over a steep cliff resembles a frozen waterfall.
- Crevasse: Deep cracks formed in ice due to movement.
- Pack ice: Floating ice sheets, seldom exceeding 5 meters thick, break easily.
Icebergs and Calving
- Icebergs: Large floating ice chunks that break off from glaciers.
- Calve: The process of large ice chunks breaking off a glacier.
Erosion and Geological Features
- Striations: Scratches on rock surfaces caused by glacier movement.
- Cirques: Bowl-shaped depressions created by valley glaciers.
- Arete: Sharp mountain ridges formed by multiple glaciers.
- Horn: Pointed mountain peaks created through glacial activity.
Depositional Features
- Till: Unsorted materials deposited by glacier movement.
- Moraine: Landform created from glacier till.
- Outwash: Material laid down by glacier meltwater.
- Esker: Sand and gravel ridge formed by streams beneath glaciers.
Water Sources and Distribution
- Meltwater: Water runoff from melting snow.
- Surface water: Freshwater bodies above ground, like streams and lakes.
- Ground water: Water that has seeped below the Earth's surface, typically found up to 100 meters deep.
Water Clarity and Habitats
- Clarity: A measure of water transparency based on suspended materials.
- Wetlands: Low-lying areas that support diverse plant and animal life, including marshes and swamps.
Streams and Rivers
- Streams: Small, rapidly moving bodies of water.
- Rivers: Larger and faster moving than streams.
Watershed Dynamics
- Watershed: Land area draining into a water body.
- Run-off: Rainwater that flows across the land surface into water bodies.
- Continental divide: Ridge marking the split between drainage areas, directing rivers to different oceans.
Erosion and Deposition Processes
- Headwaters: Source points of a watershed.
- Outflow: Water exiting a watershed.
- Erosion: Movement of sediments from one location to another.
- Deposition: Process where eroded materials are left behind.
Water Flow Characteristics
- Streamflow: Refers to the speed and volume of water passing through a watershed.
- Permeable: Capability of allowing materials, including water, to pass through.
