PRA-Duh!

cutbanks-caused because of eriosion taking away the curve of the outside of the meander.

delta-mouth of a river where sediments are carried by the river. drainage basin-land area that takes water into a river system,also a watershed.

erosion-movement of rock particles or soil in water.

mouth-it is an end point odf a river that empties into an ocean or a lake.

point bar- a point in a stream or river located in the inside curve of a meander were sediments are deposited.

Headwater-origin of a river.

Riffle-point in a river that is shallow, where sediments are deposited. Meanderind Stream- reoccuring S-shaped curves od the stream Velocity-the speed at which an object is moving

slope- an inclined surface that is a particular angle to the horizon.

watershed- a land area that is drained by a particular river system also known as a drainage basin. __

//Aquifer//  –large amounts of water stored in porous rocks under ground

// groundwater // –naturally occurring freshwater that flows or is stored underground in rock or sediments.

// Porosity-Amount of space between the sediments. // // Permeability // - ability of water to flow through a soil // Spring // - moves downhill through soil or cracks in rock until it is forced out of the ground by natural pressure // Runoff // –loss of soil, sediments as a result of being washed away by rain or water. // Unconfined aquifer // – untrapped water between two rock layers. // Confined Aquifer // – trapped groundwater located below a rock layer. // Water Table- // // top portion of the zone of saturation. //

// Zone of Saturation//  –area of soil where all the pores in soil are filled with water. // Zone of Aeration-// subsurface sediment above the water table containing air and water.
