Freshwater

. ..

Freshwater is described as having a low salt concentration (usually less than 1% of salt) media type="file" key="Above Ground Fresh Water Part 1.3gp" width="360" height="360" media type="file" key="Above Ground Fresh Water Part 2.3gp" width="360" height="360" Plants and animals living in freshwater regions would not be able to survive in areas of high salt concentration, such as the ocean

**Freshwater provides** __water for drinking__, __sanitation__, (the provision of clean drinking water and adequate sewage) agriculture, (irrigation system-//transporting water from a source of lots of water to a low water source//) __transport,__ __electricity generation__, (hydroelectric power plant) __recreation__, __habitats for a diverse range of animals and plants__ These are bodies of flowing water confined in a //narrow depression//, moving in one direction [|Info on Streams and Rivers]

**__Erosion__** is the process of rock particles and soil being loosened by the stream or river and then transported somewhere else <span style="color: #117e7e; display: block; font-family: Georgia,serif; font-size: 120%; text-align: center;">**__Load__** is the specific sediment that is carried by a stream or river <span style="color: #2c812c; display: block; font-family: Georgia,serif; font-size: 120%; text-align: center;">**__Deposition__** is the settling of the particles <span style="color: #ff00ff; display: block; font-family: Georgia,serif; font-size: 120%; text-align: center;">**__Deltas__** are land areas that are formed at the end of a river when sediment is deposited <span style="color: #ef6215; display: block; font-family: Georgia,serif; font-size: 120%; text-align: center;">**__Watersheds__** are systems of interconnecting streams and rivers (//**closed**//-into a lake; //**open**//-into an ocean) <span style="color: #4d9cfe; display: block; font-family: Georgia,serif; font-size: 120%; text-align: center;">**__Drainage Basins__** are areas of water a stream or river will drain or flow from

Meandering (Curved) Stream <span style="color: #6c6ce0; display: block; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 150%; text-align: center;">3. Braided (Separated) Stream <span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 130%; text-align: center;">These are bodies of standing (non-moving) water [|Info on Lakes]

<span style="color: #000080; display: block; font-family: 'Times New Roman',Times,serif; font-size: 130%; text-align: center;">__**Lakes**__ - usually larger and deeper (no rooted plants at bottom bc sunlight can't reach that deep)

<span style="color: #800080; display: block; font-family: Georgia,serif; text-align: center;">//Lakes can form naturally by depressions filling with rainwater or groundwater, the melting of glaciers, and also by earthquakes and volcanoes// <span style="color: #800080; display: block; font-family: Georgia,serif; text-align: center;">//Lakes that are man-made are known as// **__Reservoirs__** <span style="color: #800a0a; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">The **littoral zone** - light can reach the bottom <span style="color: #d52020; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">The **photic zone** - middle zone, some sunlight reaches this area and some plants can grow <span style="color: #eb6666; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">The **aphotic zone** - no sunlight reaches this area; no plants can grow

<span style="color: #000080; display: block; font-family: 'Times New Roman',Times,serif; font-size: 130%; text-align: center;">__**Ponds**__ - smaller and shallower (not too deep - sunlight to reaches plants, so they can grow)



<span style="color: #000080; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">__**Eutrophication**__ - an increase in nutrients/organisms stimulate excessive plant growth (algal bloom) in a pond or lake <span style="color: #000080; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">which reduces the dissolved oxygen in the water when dead plant material decompose causing other organisms to die; <span style="color: #000080; display: block; font-family: Georgia,serif; font-size: 130%; text-align: center;">eventually lake becomes dry land

<span style="display: block; font-family: 'Arial Black',Gadget,sans-serif; font-size: 132%; text-align: center;">These are vegetative areas covered by slow or non-moving water at some point of the year <span style="display: block; font-family: Georgia,serif; font-size: 108%; text-align: center;">//Swamps,// marshes, and //bogs// are all considered wetlands [|Info on Wetlands]



<span style="color: #2c3a2d; display: block; font-family: Georgia,serif; text-align: center;">wetlands are known and categorized by what grows there

<span style="color: #2d582d; display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: center;">SWAMPS: trees and shrubs(bushes) [|Swamps]

<span style="color: #2ca81f; display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: center;">MARSHES: soft-stemmed plants and grasses [|Marshes]

<span style="color: #6ae51f; display: block; font-family: 'Arial Black',Gadget,sans-serif; text-align: center;">BOGS: mosses and some trees and shrubs that can tolerate an acidic pH [|Bogs]
