Please label each picture and descriptions with a number so I can tell which picture goes with which description. Put the URL in the caption for each picture. As usual, it's best to either do the assignment in a word document and paste as you go. If you would like, you may simply put a link to your personal Wiki page to avoid loosing your work as you go.

2. etc. || 1. An alluvial fan occurs when a river is channeled and empties into a valley floor. As soon as the river is able to spread out as it leaves the mountains, it forms a fan shape at the base of the mountain.

2. etc. || 1. Larger particles such as boulders are found toward the mouth of the river at the center of the fan because there is a rapid decrease in energy of the stream as the river meets the valley floor. Particle sizes decrease with distance further away from the mouth.

|| 1.**Alluvial Fan:** Unconsolidated sedimentary deposit that accumulates at the mouth of a mountain.Deposits are usually fan-shaped in plan view.

2.**Fluvial Environment:** Rivers and valleys that were strongly affected by the climate changes.

3. **Lacustrine Environments:** Larger lakes, that move back and forth in response to the major climate cycles or opening and closing of outlets due to glaciation.

4. **Deserts:** One-third of the Earth's land surface is desert, arid land with very little rainfall.

5. **Swamps:** Wetland dominated by woody plants.

6. **Deltas:** A low triangular area of alluvial deposits where a river divied before entering a large body of water.

7**. Beaches:** An area of sand sloping down to the water of a sea or lake. || 1. Deposits are fan-shaped, Distributary pattern of channels.Course grained, most poorly sorted deposits.

2.Deposits are sometimes very thick and cover vast areas. Sediments become finer and corse grains become more rounded away from their sources.

3.Lacustrine sediments are thought to have been derived from a series of saline lakes.

4.Some sedimentary deposits are bare rock(hamada) or deflated stony plain (serirs or reg).Sediments are the shape of a cone.

5.Nutrient releases in swamps are one of the deposits.Nitrogen and phosphorus removal by cypress swamp sediments.

6.If one area gets higher sedimentation than an ancient area, you can develop a bar that has topography.

7. River Sediments are the sources of 80-90% of Beach sand. || [|www.futurefeeder.com/ category/science/]

[] [] [] || ** Alluvial Fan - ** a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads typically at the exit of a canyon onto a flatter plane. ** Lacustrine Envi. -** a system of inland wetlands and deep-water habitats associated with freshwater lakes and reservoirs. ** Barrier Islands - ** Any low sandy island that is parallel to the mainland and protects it from storms || 1. Sediment that is poorly sorted and unsually coarse.
 * Fluvial Envi. - ** an environment where rivers or water bodies flow through.
 * Deserts - ** a region arid because of little rainfall that it supports only little and widely spaced vegetation or no vegetation at all.
 * Swamps - ** a tract of wet, spongy land, often having a growth of certain types of trees and other vegetation.
 * Deltas - ** A usually triangular alluvial deposit at the mouth of a river.

2. Very thick sediment that can either be coarse or fine. 3. Composed of fine grained sediment and very tiny.

4. Rounded sediment that is mostly fine grained and there is no clumping.

5. Nitrogen and phosphorus releases from swamp water.

6. Some marine sediment is found and is very coarse grained. 7. Sediment comes from other types of water bodies and is either fine or coarse grained. ||      || **Alluvial Fan**- a fan-shaped deposit formed where a fast flowing stream flattens, slows, and spreads

 * Fluvial Environment**- an environment which is dominated by river processes


 * Lacustrine Environment**- an environment which is dominated by lake processes


 * Desert-** a region where no precipitation is received


 * Swamps-** a lowland region saturated with water


 * Deltas-** a landform that is created at the mouth of a river where that river flows into an another body of water

-
 * Beach-** a landform along the shoreline of a body of water || Coarse sediment and fan sediments thar are poorly sorted are found here

Both coarse and fine; Very thick; Channel-floor, bar, channel-top, and bar-top sediments are found as well.

Fine grained so it havs relatively low strength and relatively high settlement characteristics; Trafficability is poor.

Fine grained and rounded. -

Poor in oxygen and rich in nitrate and organic. -

Coarsest (usually sandiest) marine sediments are found. -

2) **Fluvial Environment-**an environment that is highly influenced by river process.

3) **Lacustrine Environment-** an environment that mostly relies on the lakes.

4). **Desert-** covers 33% of earths surface, where little to no rain fall occurs.

5) **S****wamp-** environment with low water and trees growing out of water

6). **Deltas-** region of water that is usually found at mouth of river.

7) **Beaches-** an area with a lot of sand and usually found at the shoreline of ocean or lake. || 1) coarse and large amount a big sediment because most likely will be rushing down the mountain and slows down.

2) Fine sediments and are rounded off because of the movement of the river.

3) fine grained because there really movement so they just settle down,

4) a lot of bare rock bit coarse and fine at the same time.

5) marine sediment, coarse because its just settles downs because of no movement.

6) beds are laid down in horizontal layers and consists of smaller grain particles.

7) most of sediments come from the rivers. || a) [] b) Fan shaped deposit area for sediments and masses of water. Sediments are usually cariied when rivers fall from mountains. c) Mostly coarse grains and any sediments carried along the path of flowing water. Fluvial Environment (rivers) a) [] b)  A mass of land that is affected by nearby rivers. c)  Coarse grains, along with rocks and sediments taken down by river
