Volcano Quick Check

Where would you most likely find volcanoes?

• far from plate boundaries

• along transform boundaries

• where two continental plates collide

• along mid-ocean ridges and where a plate is subducted

What do mid-ocean ridges and hot spots beneath ocean plates have in common?

• Rising magma moves due to density differences

• They are located along crustal plate boundaries

• Local earthquakes originate at great depths

• Neither is associated with plate tectonic motion

What provides the force that causes magma to erupt to the surface?

• Silica in magma

• Dissolved gases trapped in the magma

• Gravity in the lithosphere

• Density of the magma

The main factor that accounts for the difference between effusive and explosive volcanic eruptions is ?

• The size of the volcano's magma chamber

• The iron content or the magma

• The age of the volcano

• The silica content of the mgma

Before lava reaches the surface, the molten material is called ?

• rock

• magma

• volcanic ash

• tephra

Which of the following is NOT a step in the eruption process of a volcano?

• Temperatures in the mantle are hot enough to melt rock into magma

• As magma rises, pressure increases causing the gas bubbles to decrease in size

• Magma rises because it its less dense than the rock around it

• Magma is propelled through openings in Earth's surface, causing an eruption
