The scientists take careful looks at the rocks to study things like texture, composition, and where the rock came from (OI). That helps them figure out what type of rock it is and what it is useful for. That is why the

Basalt is mostly composed of augite, plagioclase and olivine. Augite comes in many shapes – cylinder, square, rectangular - but is usually rough and grayish black. Plagioclase is whitish brown and usually has a cubic shape with ragged edges. Olivine can be green, yellow or brown. It is usually three dimensional and octagonal.

These rocks come in colours of yellow, pink, pale grey and other light colours. The Glass House Mountains are intrusive plugs, Molten rock filled small vents or intruded as bodies beneath the surface and solidified into hard rocks, also known as Trochyte and Rhyolite. The rocks at the Glass House Mountains are extrusive igneous rocks, meaning that they were former above the ground. The rocks are extrusive as none of them have large crystals, this is because they were cooled too quickly for the crystals to

Next over a long span of time the uplift, erosion, and glaciation of the rocks formed the landscape we see today. It all started when large amounts of sand and mud eroded from ancient

However, this supercontinent didn’t stay as one for too long. Gondwana began to separate 170-180 million years ago. This was caused by continental drift which meant that the crustal plates of the earth were being dragged because of the movement in the deeper layer of rock in the mantle. Evidently volcanoes and earthquakes were two major factors in the movement of the continents. Black volcanic rocks known as Basalt excreted from the volcanic eruptions onto the sea floor in ocean areas which was called mid oceanic ridges.

Simply put, marble is just limestone that has been exposed to heat and pressure for an extended amount of time. Because it is formed by applying heat and pressure over time, it is considered a metamorphic rock. Complexities arise when impurities are introduced to the limestone undergoing crystallization. Many things can change the mineral composition of marble, such as silica. When silica is present then carbonate minerals form masses of quartz or chert crystals, but only at lower temperatures of formation.

Its composition consists of Half Dome Granodiorite, which consists of quartz, feldspar, hornblende, and

Plate tectonics is a theory that Earth’s crust is composed of nearly a dozen plates, which have shifted around the surface of the Earth over time. This theory provides a reasonable explanation for how mountains formed, and why there are earthquakes and volcanoes. Additionally, this

Purpose The purpose of this research project was to find out how each of these rocks break down with the addition of the water cycle as well as temperature changes. My parents graciously took me to Penn’s cave, noticing the karst topography, I was fascinating how things can come apart then come back together to be created. It was fascinating to see the creation process and the pressure from the precipitation and the climate it outs pressure onto the rocks in our environment with taking 80 rocks and exposed them to multiple cycles of freezing and thawing with the addition of water in the freezing.

On Earth, there are several different tectonic plates that the crust is divided into. There are both continental and oceanic plates. There are also different types of boundaries where these tectonic plates meet. The first is divergent, this is a type of boundary where the two tectonic plates move apart from each other. The second is subduction, this is a type of boundary in which an oceanic plate moves under a continental plate.

Both the Louvre Pyramid as well as the Museum of Rock and Roll created by I.M. Pei share several similarities as well as differences that make them both similar but still unique in their own ways. An example of how the two pieces are similar would be the elements that they portray within their structures. However some differences the two pieces would have are the level of interactions the structures allow their audience to have within them. Therefore the two buildings share both similarities and differences.

Usually because the plates have friction, the stresses build up on the surface. The process is relatively slow with a rate of 1 inch per year, until one of the surface slips due to high pressure. The slippage speed up to 5000 miles an hour, the pressure tears down the fault to a stuck patch which slows down the speed of the moving plates. The plates may break though the stuck patch and continue to the next knot and affecting more area.(USGS) Geology in San

The rocks do not show signs of heavy weathering. There is some white staining visible, but there is very little red or brown staining. The rocks have abundant vesicles. There is a mix of rocks with varying sizes and numbers of vesicles. Samples collected were representative of this mix.

The mantle is the largest layer of the earth and consists of dense, heated rock [6]. The lithosphere is split into tectonic plates that slowly move due to the amount of heat from the earth's center causing molten rock to move in the mantle [7]. There are seven major plates and a large number of smaller ones on earth. The relative movement in which the tectonic plates meet, establishes the type of boundary (convergent, divergent, and transform) [8]. Along these boundaries are where earthquakes occur.

Subduction is the process when in which one tectonic plate moves under the other, sinking into the mantle as the plates converge. Regions where subduction takes place are known as subduction zones. Subduction zones tend to have very high rates of earthquakes, volcanism, and mountain building. Some examples of volcanoes that are located above subduction zones would be Mount St. Helens, Mount Etna, and Mount Fuji. Furthermore, the strains, which are a result of plate convergence, are known to be the cause of at least three different types of earthquakes.
