A weak spot in the crust
What is a volcano?
100
2 Examples of a physical property.
What is density and boiling point?
100
The result of an explosive eruption - hurls ash, cinders, gases and bombs!
What is pyroclastic flow?
100
Some features found in areas of geothermal activity.
What is hot springs and geyers?
100
What do volcanoes and earthquakes have in common?
**Think about where they are located and where they occur. Both occur at plate margins (except hotspot volcanoes) Earthquakes can trigger volcanoes and vice versa. They occur when there is movement of the plates, and the bed rock fractures.
200
These are Earth's volcanic regions.
What is near plate boundaries due to weaker crust?
200
This is the resistance to flow, a physical property.
What is viscosity?
200
The stages of a volcano's life cycle.
What is active, dormant and extinct?
200
These are the three main types of volcanoes.
What is shield, cinder cone, and composite?
200
Name the parts for label 1 and label 2.
What is vent and pipe?
300
The reason Earth's volcanic regions are found there.
What is the "Ring of Fire"?
300
Three substances that have a high viscosity.
What is Aa, honey and molasses?
300
How magma makes it way from the chamber and out of the volcano?
What is the force of the expanding gases pushes magma from the chamber through the pipe until it flows or explodes out the vent?
300
How are the shield, cinder cone, and composite types different?
Shield: a wide, gently sloping mountain made of layers of lava formed by quiet eruptions Cinder Cone: a steep, cone shaped hill made up of volcanic ash, cinders and bombs piled up around the vent. Composite: A tall, steep mountain in which layers of lava alternate with layers of ash and other volcanic material.
300
Name the parts for label 3, 4 and 5.
What is crater, lava flow, and magma chamber?
400
This is the definition of a hot spot.
What is an area where material from deep within the mantle rises and melts, forming magma - located in the middle of a plate?
400
The viscosity of magma depends upon it's _____________ content and __________________.
What is silica and temperature?
400
This is how quiet eruptions and explosive eruptions are alike.
What is they are both types of eruptions and produced by volcanoes?
400
Look at the graph and answer questions 1 and 2.
1. a) silica b) other oxides c) all other solids. 2. Rhyolite- forming magma About 70%
500
The prediction to the type of features form as an oceanic plate moves across a hot spot.
What is Island chains such as the Hawaiian Islands?
500
Compare and contrast Aa and pahoehoe?
Both - types of lava and come from magma Aa = high viscosity, rough/chunky Pahoehoe = low viscosity, smooth/ropelike
500
This is how quiet eruptions and explosive eruptions are different.
What is quiet eruptions produce lava flows and low viscosity magma, while explosive eruptions produce pyroclastic flows (ash, cinders), high viscosity magma?
500
How are the shield, cinder cone, and composite types alike?
They are all types of volcanoes, have magma chambers, and form at location of weaker crust.
500
Look at the graph and answer questions 3 and 4.
3. 60% The more silica magma contains, the higher its viscosity. So, Rhyolite-forming magma would have a higher viscosity.
