Metamorphic, Igneous, And Sedimentary Rocks and Their Application to Planets in the Solar System
The objective of this study is to examine metamorphic, igneous, and sedimentary rocks and their application to planets in the solar system.
There are reported to be three primary classes of rocks, which are classified according to their origination. The three rock types are metamorphic, igneous, and sedimentary rocks. Igneous rocks are formed when bodies of magma cool. As time passes and the rocks undergo process due to various weather cycles the igneous rocks erode and the particles and chemicals, which settle into beds, become compressed or cemented forming into what are known as sedimentary rocks. In the event igneous rocks are buried and then undergo a high state of heating and compression they form into what are known as metamorphic rocks. Eventually, the rocks undergo heat and compression and then melt with the molten rock forming another igneous rock in what is referred to as the rock cycle. Rocks may be turned from one type of rock into another rock. For example, it is reported that a sedimentary rock "such as sandstone can be weathered and eroded and those fragments might eventually end up as part of a shale, a different sedimentary rock." (Rocks & Other Mineral Sources, 2012) The following illustration shows the rock cycle that the three primary rocks types undergoes in the changing of rocks from one type to the other.

I. Rock Classes and Types of Rocks
There are two classes of rocks that are formed from magma including: (1) plutonic or intrusive rocks; and (2) Volcanic or extrusive rocks. The types of rocks that are formed from the consolidation of sediments include: (1) biochemical sedimentary rocks; (2) Clastic sedimentary rocks; and (3) evaporative sedimentary rocks. Metamorphic rocks or those formed from heat and pressure include such as: (1) Geniss; (2) marble;...
238 -- 273) Coasts: Define a beach. What is the shore face along a beach? What is littoral drift (long shore sediment transport)? What is difference between Groin and Jetty? Where would you find a tidal inlet? Give an example. What is wave refraction? Identify and describe a barrier island system. What is difference between an estuary and ocean area? A beach is a land formation along the ocean's shoreline. A
Both, ironically, are forms of pressure that also cause heat and changes. Water for instance, is so abundant on earth that it drives much of weathering and erosion. Precipitation, acidic soil water and groundwater dissolve mineral and rocks; serpentinization from heated seawater causes destruction of volcanic rock or changes in other seabed rocks; and the presence of water and carbon dioxide change rock as well. This is the manner
Igneous rock is one of the three main types of rock formations making up the earth's crust. It is formed primarily through the cooling and subsequent solidification of magma or lava. Igneous rock may also form without any crystallization -- below the surface as intrusive rocks or above as extrusive. It is best to think of igneous rock as being formed with heat -- one or more of three processes:
Geology Identify each of the events represented on diagram 1. Include at least the information below: (1) Begin with the oldest event. Make sure that you somehow tell me which event is the oldest, which is the next oldest, etc. The oldest lettered event in the diagram is (C), referring to the sedimentary layer of limestone. The next oldest event is (B), which is the basalt and silt layer that infiltrated. The next
D.). A researcher may determine if a rock sample is sedimentary by examining whether it consists of grains. An igneous (from the Latin word for fire) rock, known as granite, consists of minerals like quartz, mica, and feldspar. "Igneous rocks come from melted rock material, or magma, that lies under Earth's surface" ("How can you tell," n.d.), forming when magma from inside the Earth travels toward the Earth's surface, or
The effects of liquids are not a factor in regional metamorphism as fluids cannot circulate due to the effects of pressure upon the rocks, which seal in the circulation of moisture. Regional metamorphism occurs in areas of heavy tectonic activity, near the places where the earth's plates rub up against one another. "Regional metamorphism can be subdivided into different pressure-temperature conditions based on observed sequences of mineral assemblages. It
