The difference between an eruption of Mount St. Helens and an eruption of Kilauea is that Mount St. Helens is a volcano that is about to erupt, while Kilauea is a volcano that has been erupting for years.
What is the difference between aa lava and pahoehoe lava quizlet?
The difference between aa lava and pahoehoe lava quizlet is that aa lava is more viscous and has a more intense color. Pahoehoe lava is less viscous and has a more subdued color.
Is Mount St. Helens active right now?
Yes, Mount St. Helens is active right now.
What type of eruption does Mt St Helens have?
A volcano is formed when molten rock called magma rises to the surface. When the magma is thick, it can’t be pushed up by the Earth’s gravity. This is called a locked volcano. Instead, the magma continues to rise and cool until it forms a new volcano.
How do the eruptions of Mount St. Helens and Kilauea differ quizlet?
The eruptions of Mount St. Helens and Kilauea differ in their duration, location, and magnitude.
What is the difference between explosive eruption and effusive eruption?
Explosive eruption is an eruption that results from the release of gas and ash. Effusive eruption is an eruption that results from the release of water and gas.
What is the difference between active dormant and extinct volcano?
Active dormant volcanoes are those that have been inactive for at least 10,000 years. Extinct volcanoes are those that have been inactive for at least 5,000 years.
Why is this eruption so different than Mount St. Helens?
The eruption at Mount St. Helens was a very large and powerful eruption that happened in 1980. This eruption was much more violent and destructive than the eruption that happened on Mount Pinatubo in 1997.
How do the eruptions of Mount St. Helens and Kilauea differ?
The eruptions of Mount St. Helens and Kilauea differ in that Mount St. Helens erupted more than 20 years ago, while Kilauea is still erupting.
What are the differences between pahoehoe and AA?
Pahoehoe is a Hawaiian language that is spoken in the islands of Kaua’i, Niʻihau, and Niʻihaua. It is considered a endangered language because of its low population size. AA is an English language term that refers to the American form of the drink Alcoholics Anonymous.
How did Mount St. Helens form?
The Mount St. Helens volcano formed about 12,500 years ago when the Earth’s crust and mantle moved together and created a new mountain.
Is Mt St Helens effusive or explosive?
Mt St Helens is effusive.
What are the different types of volcanoes according to shape describe each?
There are three main types of volcanoes according to shape: shield, stratovolcano, and cone. Shield volcanoes are the most common type, and are made up of a thick shield of rock that is constantly eroding. Stratovolcanoes are the most powerful type, and are made up of a series of mountains that rise quickly. Cone volcanoes are the rarest type, and are made up of a small peak that erupts suddenly.
What is the difference between calderas and craters?
A caldera is a large, deep depression on the earth’s surface that is formed when molten rock, ash, and gas escape from a volcano. A crater is a small, shallow depression on the earth’s surface that is formed when a meteor or other object crashes into the earth.
What type of eruption style does Kilauea have?
The Kilauea eruption style is a type of eruption where the molten rock called magma rises to the surface. The magma is made up of molten rock and ash from the eruption.
Will Mt St Helens ever erupt again?
There is no definitive answer to this question as eruptions from Mt St Helens can happen at any time and at any place. However, scientists generally agree that there is a low probability of an eruption happening again in the foreseeable future.
How do craters differ from Calderas quizlet?
Calderas are created when molten rock cools too quickly to solidify. This molten rock is then carved into valleys, ridges, and hills by the wind and rain. Craters are created when the molten rock solidifies and is not carved by the wind and rain.
How does the May 18 1980 eruption of Mount St Helens compare to a typical eruption of Hawaii’s Kilauea volcano?
The 1980 Mount St Helens eruption was much more severe than the current Kilauea eruption. The 1980 eruption killed about 90 people and injured more than 700. The Kilauea eruption has killed over 1200 people and injured over 2000.
What are the differences between pahoehoe and aa what kind of eruption produces these types of lava?
There are several differences between pahoehoe and aa lava. Pahoehoe is a more viscous lava, meaning that it takes more time to flow than aa. Pahoehoe also has a more rounded shape, which is due to the more viscous nature of the lava. Finally, pahoehoe is often more green than aa, which is due to the presence of pyroxene.
Did Mount Saint Helens have lava?
Yes, Mount Saint Helens had lava.
How do different volcanoes form?
A volcano forms when molten rock called magma rises to the surface from the Earth’s mantle. The magma is made up of the Earth’s mantle and the crust. When the magma is thick, the pressure from the Earth’s lithosphere and mantle pushes the magma up the Earth’s mantle and out of the Earth’s crust. The magma then cools and solidifies.
How do the eruptions that created the Columbia Plateau differ from the eruptions that create large composite volcanoes?
The Columbia Plateau is a large, composite volcano. The eruptions that created the Columbia Plateau are much more violent and have a much longer timeline.
How did Mount St. Helens erupt?
The Mount St. Helens eruption was a large and violent eruption that took place on July 20, 1980, in the United States state of Washington. The eruption was the most powerful in the Cascade Mountains since Mount St. Helens was created in 1792. The eruption destroyed most of the mountain, leaving a landscape of ash, rock and lava. The eruption is also credited with helping to create the Cascade Mountains National Monument.
What damage did Mount St. Helens?
There is no one answer to this question as it is highly dependent on the specific facts and circumstances of each instance. However, some general trends may be applicable, such as the following: Mount St. Helens was the most active volcano in the Cascade Range, and it regularly erupted large ash and gas clouds that could cause extensive damage to nearby communities.
What type of mountain is Mt St Helens?
Mt St Helens is a volcano.
When did Mount Saint Helens explode?
The Mount Saint Helens eruption occurred on April 20, 1959.
Does Kilauea have pahoehoe?
No, Kilauea does not have pahoehoe.
What is the difference between a dike and a sill?
A dike is a long, thin piece of land that is built to protect a river from flooding. A sill is a short piece of land that is built to protect a river from flooding but is not as long.
Why is Mt St Helens more explosive than Mt Kilauea?
The two volcanoes are located on different continents and have different magma chambers. The magma that makes up the volcanoes is hotter than the magma that makes up the earth. The magma chambers on Mt Kilauea are located under the earth’s surface, and the magma that makes up the volcano is located in the magma chamber of Mt St Helens.
Are Mauna Loa and Kilauea the same?
There is no definitive answer to this question as it is a matter of opinion. Some people believe that Mauna Loa is the same as Kilauea, while others believe that Kilauea is the same as Mauna Loa. There is no clear consensus on the matter.
