An Analysis of Sand and the Land it is From
Sand can tell a lot about a land. Amelia island sand most likely does the same. But before one can find out if the sand depicts the island, one most know what sand is. The pure definition of sand is grains worn from rock between 0.06 to 2.0 millimeters in diameter. Sand can be talked about as sediment when it is together with silt, gravel, and clay. (3) But on top of that basic definition, one should know what makes up sand, the ways sand is distributed, and about Amelia Island itself.
As told earlier, sand is formed from worn rock. Those rocks are the sedimentary, metamorphic, or igneous rocks. A sedimentary rock is made up of chemical, mechanical, or organic sediment. Some important types of Sedimentary rock which are distinguished by texture and chemical composition are sandstone, conglomerate, tillite, shale, sedimentary breccia, chalk, marl, coal, lignite, rock salt, gypsum. Igneous rock is rock that is formed by the solidification of a molten magma. If the rock is made from lava on the earth's surface, it is called extrusive rock, but if the igneous rock solidified beneath the earth's surface it is called intrusive rock. Metamorphic rocks start from the changing in the texture and mineral whole of sedimentary, igneous, and older metamorphic rocks under excessive pressure and heat within the earth. Some of the most common metamorphic rocks are gneiss, quartzite, schist, slate, and marble. (2)
There are tons of examples of how a type of sand tells of the land it is from because of the rocks it is made up of. A great example of that is if you find sand made from plutonic igneous rocks, then one know that the sand is probably near mountains, since plutonic igneous rocks form the bulk of mountain ranges. (6) Sand made of volcanic rocks, which is probably extrusive rock (2), are most likely near volcanoes because those rocks are formed from lava. (6) The rocks sand is made up of is essential to figuring out where the sand is from, and in the making of sand itself.
In some places there are no useable sources of sedimentary material, then the sand usually is made of organic material. Those are materials like coral, fragmented shell, and the skeletons of small planktonic organisms.

Soon after the sea reached longer distance westward and the sandy tidal deposits were converted to deep water deposits. Mancos Shale is the name given to represent these deposits, which are comprised of organic material and small particulates. Another interesting fact to note is that this type of sediment consists of fossils. These remains can include prehistoric shell fish, shark teeth, and many other types of organisms. The hills seen at the foundation of the mesa in the Montezuma Valley are comprised of gray
This sedimentary rock has hardened over the many years with sand shells, small pebbles, grains of sand and rocks of various sizes. In comparison to our 4.5 billion year old Earth, these sand shells might as well be brand new, when in reality they could be up to 1,000 years old. If the sandstone were to be replaced with calcite it would completely change the subclass of rock, it would then be chemical & organic limestone. The variation in sand stone is due to different rates of deposition and change in patterns of the sediment movement (Mc Knight, p. 384). These tightly compacted varying stones and shells will be weathered away by wind and waves over time and could eventually be reduced to a rock the size of your hand.

The rock coquina is originally a sedimentary rock. Sedimentary rocks are made up of sediments. The sediments are formed by the mechanical or chemical activities of the natural activities like running water, blowing wind, glaciers etc. this which causes disintegration and decomposition of the pre-existing rocks. The products of decay are transported to some depositional sites by the natural agencies, where they get deposited and with subsequent compaction form sedimentary rocks (Hefferan, O’Brien, 2010). . The sedimentary rocks usually accumulate under a great variety of conditions. This shows the variation in rock, chemical structure as well as in texture. Weathering is the most important process that operates in the formation of sedimentary rocks. Weathering takes place by three methods as: mechanical disintegration, rock decomposition, and biological weathering. Mechanical disintegration is due to frost action, thermal expansion and contraction, aided with gravitational forces. Due to mechanical disintegration, the reduction of size and desegregation of rocks takes place. Chemical weathering is the use of the chemical elements of the atmosphere such as moisture, carbon dioxide, and oxygen (Hefferan, O’Brien, 2010). . This depends on the composition of the rock and the size of the particles that make up them. Biological weathering is a form of weathering caused by growth of roots and burrowing of animals. The environment of a sedimentary rock can show the deposition the quality and quantity of the deposition is affected. Sedi¬mentary rocks differ from environment to environment. These environments include the continental environments such as estuarine, lacustrine (fresh and salt water), deltaic, glacial. Anothe...
The most difficult to identify was the beach ridges and the sand dunes. We were not really postive about the appearance of the beach ridges and
In April 2013, a special memorial playground opened in Sea Bright, NJ. The project, The Sandy Ground Project: Where Angels Play, was organized by New Jersey’s Firefighter’s Mutual Benevolent Association. The playground was one of twenty-six playgrounds being installed in New Jersey, New York, and Connecticut towns honoring the children and teachers killed in the massacre at Sandy Hook Elementary School. Each town that received a playground was a town directly impacted by Superstorm Sandy. This particular playground is dedicated to Anne Marie Murphy, a special education teacher, wife, mother, and hero who passed away during the horrific shooting and is located on Sea Bright Beach which was brutally devastated by Superstorm Sandy.
Since the rocks are from the Earth’s crust, a natural deduction is that the rock sample shares a similar chemical composition. The Earth’s crust predominantly contains silicon and oxygen which bond together to form a group of minerals known as silicates (SiO4). A tetrahedral chemical structure indicates a crystal-like structure. Silicates often bond with other cations such as iron, magnesium, sodium, aluminum, potassium, and calcium which gives rise to new physical and structural properties (“Earth121: Minerals (Part One)”
Sedimentary rocks are non-crystalline rocks created from particles of other rocks. These rocks are associated with fossils. The process of lithification creates these rocks as the rock is compacted and chemical deposits fill the gaps. Clastic rocks are weathered fragments. Non-clastic rocks are divided into biological and chemical. Precipitate forms chemical rocks and biological fragments form biological rocks.
The first misconception, that all rocks are formed the same and are composed of the same materials was put to rest when we explained to students that sedimentary rocks are formed from by pressure and time and are made up of many types of materials such as mud, sand, pebbles, bones, etc. This became more concrete for the students when we had them create their own rock out of different sediments (starbust and sour patch kids). This also put to rest the other misconception that the streaks on the rock are just its color and nothing else. The students realized by applying pressure to the starburst and having it form into one that the streaks were the result of the different sediments forming
Ecosystems rely on the interactions between the four spheres of the biophysical environment, the lithosphere, hydrosphere, biosphere and atmosphere for its unique character and functioning. These biophysical interactions and their processes have significant dictated the coastal sand dunes. Coastal sand dunes are large accumulations of sand located immediately behind the active beach zone. They are found on all the world 's continental land masses. This is evident in the effects of the atmposhere and hydrosphere as well as with geomorphic and biogeochemical processes, have on the dunes. Therefore, the variety of factors arising from the interactions between the spheres has lead to diverse ecosystems and their functioning.
A rock is a naturally occurring substance or solid material which is composed of one or more minerals. There are three types of rocks namely – Igneous , Metamorphic and Sedimentary rocks. These rock are in a continuous cycle of process whereby they are changed from one type of rocks to another which may be of a different mineral composition. This processes is called Rock cycle. The rock cycle is a process that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes.
The Sand Cone Model describes business improvement as a process which should be based on improving specific competitive dimensions in a different order (Meredith & Shafer, 2013). For instance, a business which is struggling with quality outputs should place an emphasis on improving the quality of its outputs first. Businesses that produce high quality outputs are successful over the long term. Matthew 7:24-25 (ESV) states, “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock.” When a business builds its foundation on
