Magma

What are some examples of supervolcanoes? Mount Toba is a supervolcano in Indonesia. This volcano spewed out 700 cubic miles of magma, equal in mass to 19 million empire state buildings. This eruption was so big that scientists found ash from Toba in an East African rift valley. A massive plume eruption took place right at the P-Tr boundary. A new plume burned through the crust in what we now know as Western Siberia to form the "Siberian Traps," gigantic flood basalts that cover 2.5 million sq km

An army of soldiers, mages and slaves head for an abandoned field in the midst of the kingdom of Buhl. With them they bring many cages of all sizes and materials. As the army tramples forward, they find a crack in the sky that seems to be pulsating with magic. The General of the army peers at the crack and lets out a sharp whistle, while rotating his hand in the air. "CIRCLE UP! I WANT THIS PLACE LOCKED DOWN IN TEN!" The General is an older man, whos become quite grizzled in his age. He is a tall

fragments, such as either volcanic clinkers, cinders, volcanic ash, or scoria that has been built around a volcanic vent and produce Lava, ash, smoke. Shield What is it? A shield volcano is a type of volcano usually built almost entirely of fluid magma flows How are they made? Shield volcanoes are built

The Axial Seamount is an active underwater submarine volcano that is located in the Northeast Pacific Ocean. The purpose of this paper is to research and examine the Axial Seamount and why it is such a natural geological phenomena. The Axial Seamount is the location of the first underwater volcano observatory, the NeMo. The Axial Seamount has had activity in the recent years of 2015, 2011, and 1998. The Axial Seamount has held many expeditions since 2011. For the past 6 years, there has been an

can put out heat over 700℉. This means most of the rocks around the vent will melt and release their minerals inside. Most of the salt in the ocean that is not in the water settles on the bottom and combines with the rock. Volcanic vents are where magma is pushed near the surface and heats the rocks and seawater above it. This will blow all of the dissolved minerals all over the place

Sparks explains how not only can rising magma cause the earth the bulge, but it can also trigger earthquakes. Magma can trigger earthquakes because as it moves towards the surface of the earth, rocks will move and cause stress on surrounding rock material. These earthquakes are relatively small and last for a long period, which distinguishes them from other seismic activity. The earthquakes are slow because they resemble the fluid movement of the magma beneath the crust. These small scale earthquakes

Volcanoes are a mountain with a crater in the middle -The crater will have magma inside of it. -The magma will become lava when it comes out of the top. - The lava will harden and is called igneous First there are tectonic plates that collide together that will cause an earthquake which can make the volcano erupt. -Then magma comes out the top and it becomes lava. -It can spread long distances or not that far depending on the size of the volcano. -Even a small volcano can spread miles of smoke

area about half of the earth has plenty of basalts and rhyolites with rock and it can be found in the surrounding region. This shows history of a past super volcanic eruption that has changed the world and its atmosphere to what it is today. This magma once has too much pressure built up will erupt which will be known as a super-eruption. As authors Ellis and Mark wrote that “[super-eruptions] are considered to be the greatest geological hazard to mankind . . .” (135). So if Yellowstone Caldera suddenly

In June 1783 Laki erupted explosively killing 25% of the population in Iceland (which is where its located) and 50% of livestock. Laki’s last eruption was in 1783 which lasted an eight month period between 1783-1784 that was about 233 years ago when it erupted 14 cubic km of lava and tephra which means types of materials that are erupted from a crater or volcanic vent an then depostited in to the air. Laki Volcano is near Eldgja and the village of kirkjubaejarklaustur, the two plates that made Iceland

The Granite rock is an intrusive rock that formed from magma coming from beneath the earth’s surface. It went through a slow cooling process that allowed the minerals; mainly quartz and feldspar to form where the result is the coarse texture. The granite went through hydrothermal metamorphism (involves hot fluid) and contact metamorphism. The gneiss, however, being able to withstand high temperatures came from a large country rock. This piece of gneiss broke off from the country rock and got trapped
