The difference between cinder cones and composite and shield volcanoes is that cinder cones are made of small pieces of cinder that are stacked on top of each other, while composite and shield volcanoes are made of large pieces of cinder that are attached to the earth.
What makes a shield volcano A shield volcano?
A shield volcano is a volcano that is located in a shield of rock that is located between the Earth’s crust and the mantle.
What is the difference between a shield volcano and a stratovolcano?
A stratovolcano is a type of volcano that is made up of layers of molten rock and ash. Shield volcanoes are a type of volcano that is made up of pieces of ice that are stuck to the sides of a mountain.
What are composite cones?
A composite cone is a type of cone that is made up of two or more smaller cones.
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 more viscous and has a more complex eruption history. Aa is more like a stream of lava, and typically does not produce a pahoehoe lava flow.
Why are pyroclastic flows not associated with shield volcanoes?
Pyroclastic flows are not typically associated with shield volcanoes, as the two types of volcanoes have different mechanisms for creating pyroclastic flows. Shield volcanoes typically generate a more viscous magma that is more difficult to travel through the Earth’s crust and magma chamber. This makes pyroclastic flows more likely to form from the magma that is released from the volcano.
How are aa and blocky lava similar?
Blocky lava is made up of small pieces that are not as smooth as aaa.
What is scoria and how does it differ from pumice?
Scoria is a type of rock that is made up of small, rounded pieces. It is often found in areas with a lot of ash and volcanic rocks. Pumice is a type of rock that is made up of large, flat pieces. It is often found in areas with little ash and no volcanic rocks.
What are the characteristics of cinder cone volcanoes?
One of the most common characteristics of cinder cone volcanoes is that they are very young, formed only a few hundred years ago. They are also very active, erupting often and producing large eruptions of ash and rock.
Which is faster pahoehoe or aa?
Pahoehoe is faster.
How do volcanic bombs differ from blocks of pyroclastic?
Volcanic bombs are made from molten rock that is heated by the eruption. Pyroclastic blocks are made from solid rock that is shattered by the eruption.
Why do lava domes and composite volcanoes differ in morphology?
Lava domes are more dome-like in shape, while composite volcanoes are more cone-like in shape. Composite volcanoes are formed when two or more magma chambers fuse together, which causes the magma to rise and form the cone-shaped head.
How are shield and cinder cone volcanoes similar?
Shield and cinder cone volcanoes are similar in that they are both volcanoes that are located in an area that is underlain by a mantle of rock. The two volcanoes are also similar in that they are both fed by the magma that is located inside the Earth.
What are the differences between pahoehoe and AA?
There are a few key differences between pahoehoe and AA. For one, pahoehoe is a more complexfont, typically featuring more than 12 letters. AA, on the other hand, typically has 11 letters. Additionally, pahoehoe is typically less condensed, meaning it has more open vowels and is less centralized around the letter “a.”
How is aa and pahoehoe produced by the same volcanic eruption?
Aa and pahoehoe are produced by the same volcanic eruption. The two terms are used to describe the ash and lava that are expelled from the volcano.
What is a cinder composite volcano?
A cinder composite volcano is a volcano made up of pieces of different cinders.
Which of the following choices best explains the difference between a crater and a caldera?
A crater is a depression on the surface of a planet or moon that is the result of a meteor or comet hitting the surface. A caldera is a large, deep depression on the surface of a planet or moon, caused by the eruption of a volcano.
How does the composition and viscosity of lava flows differ between composite volcanoes and shield volcanoes?
Lava flows are composed of a variety of materials, including ash, magma, and rocks. The viscosity of a lava flow can vary depending on the composition and texture of the materials. Composite volcanoes are more viscous than shield volcanoes, which is why they are more difficult to control.
How are lava domes different from cinder cones?
Lava domes are more rounded than cinder cones because they are built from molten rock that has solidified over time. This makes them less steep, which is why they are often used as tourist attractions. Cinder cones, on the other hand, are made from solidified ash that has been heated by the sun. They are typically much more steep, making them perfect for mountaintop-sitting.
Why are shield volcanoes wider than composite volcanoes?
Shield volcanoes are wider than composite volcanoes because the two types of volcanoes have different shapes. Composite volcanoes are made up of pieces of different shapes, such as a cone, volcano, or shield. Shield volcanoes are made up of one or more pieces that are shaped like a shield.
Do shield volcanoes have secondary cones?
Yes, shield volcanoes do have secondary cones. Secondary cones are formed when the ash and magma from the volcano escape and form a new cone.
What makes pyroclastic surge different from pyroclastic flow?
Pyroclastic surge is a type of eruption that is caused by the release of gas and ash from a volcano. This eruption is typically more violent and can cause a large area of the volcano to collapse. Pyroclastic flow is a type of eruption that is caused by the release of gas and ash from a volcano. This eruption is typically less violent and can cause a smaller area of the volcano to collapse.
What is a shield cone?
A shield cone is a type of cone-shaped device used to protect people or objects from projectiles. Shield cones are typically made from metal or plastic and are designed to deflect projectiles away from their target.
What is the difference between a cinder cone volcano and a composite volcano?
A cinder cone volcano is a type of volcano made up of small pieces of ash and cinders. Composite volcanoes are a type of volcano that combines the features of two or more cinder cone volcanoes.
What is the difference between magma and lava?
The difference between magma and lava is that magma is molten rock that is under the Earth’s surface, while lava is a hot, gas- and ash-filled rock that rises to the surface.
When contrasting lava from a composite volcano to lava from a shield volcano?
Lava from composite volcanoes is typically more orange than lava from shield volcanoes. The orange color is due to the presence of ash and other materials that have been ejected from the volcano. Lava from shield volcanoes typically has a light green color, due to the presence of magma and other materials that have been drawn up from the Earth’s surface.
Is pahoehoe a pyroclastic material?
There is no consensus on whether pahoehoe is a pyroclastic material. Some researchers believe it is, while others believe it is not.
What is the difference between aa lava and pahoehoe lava quizlet?
The two types of lava are different. Aa lava is a more viscous, more molten lava. Pahoehoe lava is a less viscous, more solid lava.
What type of rock is pahoehoe?
Pahoehoe is a type of volcanic rock that is a greenish-gray in color.
How is a crater different from a caldera quizlet?
A caldera is a large, circular depression caused by the eruption of a volcano. A crater is a smaller, more regular hole in the earth’s surface.
What is one way that cinder cones differ from composite and shield volcanoes quizlet?
Shield volcanoes are formed when molten rock called magma rises to the surface. When the magma cools, it forms a shield around the volcano. Composite volcanoes are formed when two or more magma chambers mix and create a new volcano.
