that zone is more subject to seismic disasters. Tectonic, volcanic, collapse and explosion, are the four different types of earthquakes. A tectonic earthquake is one that occurs when the earth 's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes. A volcanic earthquake is when a volcano erupts and shakes the plates.
They can determine how often a volcano “usually” erupts by dating each of these layers using a variety of methods. It is about understanding how old each layer is, then predicting the next eruption using the age gaps that are acquired. F. What type of volcano is Dante’s peak considered? The type of Volcano Dante’s peak is a stratovolcano.
So latent heat of fusion is also the enthalpy of fusion of a substances and molecule, or in another words is the changes of enthalpy of a substances or molecule when it starts to melt. The solid phase has a lower internal energy than the liquid phase, so energy is needed for a solid to melt into liquid (En.wikipedia.org, 2016). Phase transition is used to describe substance changes from
The Yellowstone Caldera is a volcanic feature formed by the collapse of a volcano into it’s own magma chamber in the North Western edge of Wyoming. Calderas are cool, I’ll give you that. But do you know what’s even cooler? A supervolcano.
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.
They are built up when eruptions occur. With each eruption, erupted lava and ash adds another layer to the growing volcano. After many eruptions, the volcanic material pile up around the vent(s). These piles form what we recognize to be Aerial Volcano.
Fractures caused because of water pressure due to the brittle nature of the rock can be seen, this is the jointing in the basalt. We walked down the creek path to closely observe the basalt structure and saw a complex joint system, which we believe after further reading happened after the lava solidified into basalt it underwent contraction due to cooling. This shrinkage resulted in tensile strain to be applied on the rock mass, because the upward and downward tension could be put up by the molten elastic rock underneath the crust whereas the horizontal stress caused the outer crust to crack, which resulted to form a joint system and horizontal pipe like structure
The planet’s surface contains large amounts of potassium and sulfur. The crust measures 300 to 400 miles in thickness and is made up of silicate rock. Beneath the crust is the mantle which measures 400 miles in thickness. The mantle is also composed of silicate rock. Mercury’s core makes up 75% of the planet and is composed partly of liquid iron.
When the layers of the Earth move it causes the tectonic plates (aka: plate tectonics) to move which causes the Alaskan Way Viaduct to collapse. The layers of the Earth are the inner core, outer core, mesosphere, asthenosphere, upper rigid mantle, oceanic crust, and the continental crust. The Density Column lab showed how things can have different densities like the layers of the Earth. It also showed how things that are most dense stay more towards the bottom and least dense stuff stays more towards the top.
I think the difference in temperature can cause convection currents, because like the lava lamp the more hot something is the more dense it becomes then it rises to the top, the more cool something gets the less dense it becomes and it sinks to the bottom. So when plate tectonics go through a convergent boundary it slides under the crust it then has a current, which is caused from convection. Which then spreads. Then it heats up, and rises to the top. Once it 's at the top it cools down and becomes less dense then this process is repeated.
Caroline Burns 159001444 Museum Assignment 2 3) Basalt is an igneous and mafic rock that compromises most of the volcanic rocks. It is dark black and gray colored. It is rough and has an uneven rectangle-box shape. Basalt is from Somerset and is four point two billion years of age.
Bedrock is one of the strongest rocks known to man and takes the strongest man-made technology to break through. Clearly, volcanoes are a very strong disaster that can destroy almost anything. Their winds are the most powerful from the eruption. These are formed from the earth 's crust and the tectonic plates under it.
