how does erosion of the cromer forest beds produce valuable fossils?

because it makes available for inspection the sediment of a once delta of a mighty river.

Wind erosion is both a destroyer and preserver. When wind erodes a place, certainly it deposits the sediments and leaves, seeds etc. to other place, giving the other place a new life.\nHowever in some cases it acts only as a destroyer, only because of human activities as they cut the trees but don't bother to plant again. So fertile land gets wasted.

Stream beds change due to sediment load that it carries & amount of water. They can meander or cut deeper into their bed. Oxbow lakes can form when meanders are cut off from the rest of the stream.\n\nRocks weather by wind & water. Self explanatory. Rock is removed by the wind & water and redeposited somewhere else as sediment.\n\nShorelines can either build up or erode depending on where they are located. Hurricanes can wash away shorelines or build them up too. Depending on how intense the storm is & amount of storm surge/ high tide or low tide, etc. Barrier islands are constantly changing. They move further inland during transgressions & move back out again during regressions. Hurricane can also close or open new inlets along barrier islands. Many of NC's barrier inlets have been closed & reopened by major hurricanes over the past couple hundred years.\n\nKarst topography. Areas w/ limestone bedrock will form sinkholes where the limestone is dissolved by naturally forming acids. This occurs especially where too much water is pumped out from these limestone aquifers. You can get sinkholes & sinkhole lakes/ponds. Lots of these in Florida.

We had a teacher at school who did a project on erosion that I still remember, so it must have taught us somehting.\n\nHe got a wheelbarrow load of fine sand and piled it into a mound out in theplayground. Then he got a hose and wet the top of it and let some of it wash away. \n\nNot only do you see a practical demonstration of the way that rain erodes mountains and forms streams and rivers but by varying the steepness of the mound or the speed of the water falling on it you can form shallow, broad wandering 'rivers' or steep sided straight valleys and so on.\n\nWe all thought it was prety cool that you could actualy see the rivers form as you watched.

Check out this site: http://www.expanding-earth.org/\nSome scientists may dispute the notion that additional solid matter is created from solar energy by photosynthesis in plants and other living organisms, but they should consider coal beds that were formed from trees in the Carboniferous (~360 to ~290 Ma) but are now buried under deep overburden that accreted later. The huge fossilized tree trunks found in the Petrified National Forest near Holbrook in eastern Arizona are additional evidence of mass from solar energy. Also consider the massive deposits of limestone created by marine fauna (fish, coral, bivalves, microfossils, etc.) in earlier epochs and this growth continues today. Today, piles of leaves, wood chips and fallen trees are rapidly converted to soil by nematodes.  The whole question of added mass needs further research to more accurately determine the volume and sources.

You should go to an university to check that out. Ask for the geology department and ask for a paleontologist, he(she) will help you out.\nI am no expert on this but it looks more like a type of crab, trilobites the head tend to be preserved more easily than the tail. It seems that you can carve the fossil out that will help, but ask a paleontologist first.

Climate & erosion can effect mountain formation & evolution.\n\nFormation\nThe climate will determine the types of rocks that exist before & during the formation of a mountain. Chemical & mechanical weathering changes pre-existing rocks. The actual orogeny will determine the final outcome of the rocks as they are usually metamorphosed during this time. Depending on the final type of rock formed, rates of erosion may increase or decrease. Some rocks are more resistant to erosion than other such as silicon dioxide.\n\nEvolution\nAs the mountains form, climate plays a role in the erosional process. Wetter climates tend to have more erosion by water. In drier climates wind will determine the amount of erosion. Climate determines how fast or slowly rocks will erode.\n\nAs mountains erode, they will readjust in height in a process called isostatic adjustment. Mountains have "roots" that reach deep in the earth. The earth's crust is much thicker here versus other parts of the continental crust.\n\nWhen you take the weight off by erosion, the mountain rises slightly therefore will not change in height. This is much like stacking several wooden blocks in a pail of water. When you take one block off the rest will rise in response.\n\nHowever, time & rates of erosion will determine the ultimate fate of a mountain. At some point, the mountain will eventually rise to it's capacity. When it has reached this limit, it is possible for the mountain to erode to the surface.

You see there are different kinds of aeolians deposits.\nIf you look at the sites you will see different formations. You will see at the windward side erosion occurs, in where wind pick up sediments, like sand, and deposits it at the leeward side or simply at the back.

First off sedimentary rock is necessary for oil and gas formation. A known anticline (hill shaped folding),  is necessary for the entrapment of the oil and gas.  The rock needs to be old enough for the oil and gas forming to occur. Your not going to find alot of oil in gas in quaternary or tertiary rock. I live in an area known as the Bradford oil field and the rock age here is mainly Devonian. \n\nMany paleoentologists are being employed these days in this field of oil exploration. A core or test sample is drilled and brought to the surface and from the fossils found a determination can be made if this is a possible site for oil. (2 cent version)

Well let's put it this way.  My geography professor told me that the erosion rate at the top of Mt. Everest is about 10 cm. per 1000 years, and Everest is over 28,000 feet tall.  I'll leave you to do the math.

Fossils (from Latin fossus, literally "having been dug up") are the mineralized or otherwise preserved remains or traces (such as footprints) of animals, plants, and other organisms. The totality of fossils and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record. The study of fossils is called paleontology. Because fossils are by their nature old, the word has also entered the modern vernacular as a derogatory term for an elderly person. Fossils are like coal, oil, etc or u can try these:\n\n\nKind of fossils:\n1 Trace fossils \n2 Microfossils \n3 Resin fossils \n4 Pseudofossils \n5 Living fossils
