Why is silica rich magma explosive?
This is because silica-rich magma is thicker. The thicker the magma, the chance for the dissolved gas in there to escape is less likely. This causes an explosion. When the gases do escape, they cause an even bigger explosion
What type of magma causes violent erpuptions?
Highly viscous felsic magma causes the most violent volcanic eruptions.
Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
How can magma cause the plates that carry the continents to move apart?
magma is very hot so as it boils it moves the plates of the earth causing the continents to slowly move apart
How high does it have to be on the Richter scale to cause a volcano eruption?
Earthquakes do not cause volcanoes. However, magma moving to the surface rapidly can produce tremors. Volcanoes can cause earthquakes, but not vise-versa.
Describe the factors that might cause magma to form a laccolith instead of a sill?
Simple terms- Chemical and Physical particles
What does magma pushed into a thick sill form?
magma pushed into a thick sill can form what
What is a hardened layer of magma called?
laccolith
What is magma in a sill which pushes up to form a rock dome called?
Laccolith
What is rock body made from slow cooling magma and with a mushroom shape?
A laccolith.
How might the landscape above a laccolith look?
it would look like an uplift or dome because the laccolith below is a lens-shaped mass of magma that pushes the rock above it upward
What is the difference between a sill and a laccolith?
Laccoilith forms as an intrusive structure and an Eroding Laccolith has been exposed to the Earth's surface by erosion of the rock layers above it.
What is formed when magma begins to form a dome shape which will push the crust outward in a hill formation?
A+ Laccolith
How might the surface landscape above a laccolith look?
it would look like an uplift or dome because the laccolith below is a lens-shaped mass of magma that pushes the rock above it upward
How might a surface landscape above laccolith look?
it would look like an uplift or dome because the laccolith below is a lens-shaped mass of magma that pushes the rock above it upward
How might the surface landscape above laccolith look?
it would look like an uplift or dome because the laccolith below is a lens-shaped mass of magma that pushes the rock above it upward
What is an igneous intrusive feature that forms from a lens shaped mass of magma that arches the overlying strata upwards?
Laccolith
