Volcano Notes Check

Where would I find a hot spot?

This volcanic type is created differently from other volcanic types in that it ...

• it is formed by a unique formation process

• it is created through erosion

• it is the same as other volcanic types

• it has no formation differences

The 3 types of convergent boundaries are:

• continental-continental, oceanic-continental, oceanic-oceanic

• divergent boundary, transform boundary, convergent boundary

• continental rift, subduction zone, collision zone

• subduction, transform, divergent

What does each one create?

The movement of lithospheric plates that causes volcanic eruptions through convergent boundaries can be described as...

• It causes volcanic eruptions by creating fissures on the Earth’s surface.

• It causes volcanic eruptions by creating subduction zones where one plate moves beneath another.

• It leads to volcanic eruptions by increasing the pressure within the Earth without melting rocks.

• It does not affect volcanic eruptions at all.

What is a volcano?

• A) A place where lava, ash, or molten rock come out of the ground.

• B) A mountain that forms when layers of lava and ash erupt and build up.

• C) Both A and B.

• D) None of the above.

A volcano is...

• A natural formation that continuously erupts lava

• An opening in the Earth's crust where magma escapes

• A hill with no geological significance

• A formation only found underwater

Volcanoes form at divergent boundaries by...

• Magma rising to the surface through the gaps

• Subducting plates create melting hot spots.

• Mantle plumes reach the surface lifting the crust.

• Atmospheric pressure forces magma upwards.

Identify the three locations where volcanoes form.

• Convergent boundaries, Divergent boundaries, and hotspots

• Fault lines, Mid-ocean ridges, and subduction zones

• Rifts, trenches, and plate interiors

• Mountain ranges, river deltas, and ice fields

Fill in the blank: The part of the volcano where magma is stored is called the _________.

• Magma Chamber

• Lava Tube

• Volcanic Crater

• Eruption Vent
