general characteristics of clastic sedimentary rocks:\n\nthey may...\ncontain layers\nbe dull & earthy in appearance\ncontain clastic material (small grains of rock)\ncontain fossils\nrub off easily b/t fingers\nloosely "glued" together w/ minerals such as iron oxide & calcite

Sedimentary:\nAndesite is an igneous rock with feldspar, quartz, pyroxene, biotite and hornblende minerals in it. The feldspar, pyroxene, biotite and hornblende will weather out to become clay. In some situations they may become grains or clasts. The quartz will become grains. So they will become shale and sandstone (possibly conglomerate), depending on the amount of weathering. \n\nMetamorphic:\nAssuming you mean direct metamorphism of andesite, the andesite will become greenstone, greenschist, amphibolite, or granulite depending on the degree of metamorphism.\n\nIf you are having trouble figuring out the different metamorphic series go here and click on the links marked by "rock cycle stage" to see diagrams:\nhttp://csmres.jmu.edu/geollab/Fichter/Wilson/Rkcyckey.html

Characteristics are Mass, Volume, Density and viscosity.\nDensity (rho)=mass/volume

Minerals are:\n1. naturally formed\n2. solid\n3. homogeneous (same composition throughout)\n4. have a defined chemical composition \n5. have a fixed crystaline structure

Andalusite is a polymorph with two other minerals; kyanite and sillimanite. A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals. A unique variety of andalusite is called "chiastolite". It contains black or brown clay and/or carbonaceous material inclusioned in the crystal. These inclusions are arranged in regular symmetrical shapes. Usually they are in the form of a cross or X. \n\nPHYSICAL CHARACTERISTICS:\nColor is white, red, brown, orange and green. \nLuster is vitreous. \nTransparency crystals are transparent to translucent. \nCrystal System is Orthorhombic; 2/m2/m2/m \nCrystal Habits include prismatic crystals with a square cross section terminated by a pinacoid. also massive and granular. \nCleavage is good in two directions. \nFracture is splintery to subconchoidal. \nHardness is 7.5 \nSpecific Gravity is approximately 3.15+ (above average) \nStreak is white. \nAssociated Minerals are cordierite, biotite, feldspars, quartz, kyanite and sillimanite. \nOther Characteristics: dark inclusions produce cruciform shapes in the variety, chiastolite. Index of refraction is 1.632-1.638. \nNotable Occurrences include Andalusia, Spain; Austria; California, USA and China. \nBest Field Indicators are crystal habit, color, inclusions (if present) and hardness.

This is a great way to begin understanding the different forces that shape the land.  It is important to remember how the rocks came to be found, Metamorphic rocks from Michigan that may have been dug up from a deep quarry or found on the surface exposed by glacial action.  In N Carolina they could be sedimentary rocks exposed by water erosion.  In Florida they could very likely be calcium carbonate deposited by ancient coral reefs.  A simple understanding of these and other rock forming processes would make a prize winning 4th grade report.  Good Luck!

Applications of the concept that the present is the key to the past in the earth's history:\n1. volcanology: Today, volcanic rocks are generated at active volcanic centers--from the cooling of lava. We assume that when we map out similar rocks in older strata that they also formed at volcanic centers--even if there is no active volcanism in the area today. \n2. paleontology and paleoenvironment: We know that certain plants and animals live in the ocean and certain organisms live on land.  If we find fossils of marine organisms(like oysters, corals, ammonoids, shark teeth) in sedimentary rocks on high mountains, we interpret that the strata were originally deposited on the sea bottom that has since been uplifted.\n3. paleoenvironment: we know that modern desert areas covered by dunes have certain characteristics--that the dunes have certain types of crossbeds, the sand is well-sorted and well-rounded, for example. If we observe similar characteristics in sandstone beds of the Colorado Plateau, for example, that is considered evidence for an arid desert environment in the past.\n4. Modern plate boundaries are associated with major fault systems, certain rocks types, etc. In  the Sierra Nevada, geologists have mapped out ancient fault boundaries that put marine sedimentary rocks against dissimilar volcanic arc-related rocks. The patterns they have mapped out are considered evidence that the plate boundary of North America was once a convergent margin located farther east than it is today.

1) sandstone, shale, conglomerate (by size of clasts)\n2) mainly carbonates (limestone, dolomite)\n3) c\n4) b\n5) Not sure... maybe b, because it can be organic or non-organic?

rock refers to solid mineral deposits. Rocks are minerals, but not all minerals are rocks.\nSome minerals, given time and circumstance, form solid deposits. These solid mineral deposits are known as rock. Pressure, temperature, erosion, and friction are forces that effect the formation of rocks. The rock formation process allows geologists to classify rocks into three groups: sedimentary, igneous, and metamorphic. Sedimentary rock forms when layers of "sediment" (small particles of solid minerals like sand and pebbles) fuse together over time under the force of water or wind. Sedimentary rock is commonly found in and near riverbeds and streambeds. Igneous ("fire-formed") rock forms after minerals are heated to extremely high temperatures and then allowed to cool.

Hi, Seaford cliffs are chalk/flint; and the geology is from the Cretaceous period. Google 'geology seaford' and see what you come up with!\n\nAlso check http://www.discoveringfossils.co.uk/locationsSE.htm - there's not much detail, but it gives you a little bit of information. Seaford's towards the bottom of the list.\n\nGood luck with your homework!

how related is your question with Zoology?\nAnyway\nmudstones are\nPhyllite\nShale\nSlate\nShist\n(depeding on how much degree original sedimentary rock is metamorphosed)

There are three basic types of rocks: igneous, sedimentary, and metamorphic.\n\nIgneous rocks are formed from molten magma or lava. Igneous rocks vary greatly in grain structure and size, depending upon how quickly the magma or lava cooled. An example of an igneous rock is obsidian.\n\nSedimentary rocks are formed when layers of sediment are compacted by pressure. They are often composed of fragments of materials derived from other rocks and minerals, especially quartz.\n\nMetamorphic rocks occur when igneous, sedimentary, or previously-formed metamorphic rocks are submitted to extreme heat or pressure beneath the earth's surface, changing their structure and appearance. They often exhibit "foliation" or color banding when mineral crystals are elongated due to pressure. An example of a metamorphic rock is slate.

Sedimentary rock, for the most part, is created from sediment in large bodies of water.  The large land masses that are coated in sedimentary rocks were once the beds of large bodies of water.
