Terms | Definitions |
|---|---|
 Advancing Glacier | block of ice which advances over land and water. Increasing in size |
| Amplitude | the height of a wave's crest |
| Atlantic Coast | where one can find semidiurnal tides in the US |
| Barrier Islands | A low, elongated ridge of sand that parellels the coast. |
| Beach Norishment | Process in which large quantities of sand are added to the beach system to offset losses caused by wave erosion. |
| Breakwater | Human made wall built in the water parallel to shore to block incoming waves. |
| Brittle Behavior | when a material is stressed passed the yield point and responds by rupturing or breaking |
| Coastline | The coast's seaward edge; the landward limit of the effect of the highest storm waves on th shore. |
| Coasts | A strip of land that extends inland from the coastline as far as ocean-related features can be found. |
| Column | A feature found in caves that is formed when a stalactite and stalagmite join. |
| Condensation | the process of changing from a gaseous to a liquid or solid state |
| Confined Aquifer | (also known as artesian or pressure aquifers) exist where the groundwater is bounded between layers of impermeable substances like clay or dense rock. When tapped by a well, water in confined aquifers is forced up, sometimes above the soil surface. This is how a flowing artesian well is formed. |
| Desert | One of the two types of dry climate; the drier of the dry climates |
| Emergent Coast | a coast where land that was formerly below sea level has been exposed either because of crustal uplift or a drop in sea level or both |
| Equatorial Low | Low pressure Zone at Equator; Abundant Precipitation/Tropical Climates |
| Evaporation | the process by which water changes from liquid form to an atmospheric gas |
| Fractures | Any break of rupture in rock along which no appreciable movement has taken place |
| Geothermal Energy | Natural steam used for power generation |
| Glacial Balance | Balance between input (freezing) and output (melting) in a glacier. |
| Glacial Grooves | Scratches and grooves on bedrock caused by glacial abrasion |
| Glacial Ice | water in the solid state within a glacier: forms as snow partially melts and refreezes and compacts so that it is transforms first to firn and then to glacial ice |
| Groin | A short wall built at a right angle to the seashore to trap moving sand |
| Icebergs | large masses of ice detached from glaciers and floating in the sea. About 90 percent of an iceberg's mass is below the surface of the water |
| Interiror Drainage | A discontinuous pattern of intermittent streams that do not flow to the ocean |
| Longshore Transport | movement of sediment along the shoreline due to waves and currents |
| Losing Stream | Streams that lose water to the groundwater system by outflow through the streambed. |
| Melting | Solid to Liquid |
| Neap Tide | The lowest tidal range, occurring near the times of the first and third quarters of the Moon. |
| Pacific Coast | where one can find mixed tides in the US |
| Precipitation | the falling to earth of any form of water (rain or snow or hail or sleet or mist) |
| Primary Porosity | refers to the original porosity of the rock that resulted from the sediment deposition and rocks formation. this can be reduced due to lithification |
| Rainshadow Desert | A dry area on the lee side of a mountain range. Many middle-lattitude deserts are of this type. |
| Sand Dunes | hills of sand shaped by the wind |
| Seawall | A barrier constructed to prevent waves from reaching the area behind the wall. Its purpose is to defend property from the force of breaking waves. |
| Secondary Porosity | Secondary - forms after the material does; A.) fracture - in any rock but only type of porosity in igneous intrusive rocks and metamorphic rocks; B.) solution - much like the carbonation of limestone's (decomposes it) |
| Shore | Seaward of the coast, this zone extends from the highest level of wave action during storms to the lowest tide level. |
| Shoreline | The line that marks the contact between land and sea. It migrates up and down as the tide rises and falls. |
| Silt | ... |
