Question

Match the following. Match the items in the left column to the items in the right column.

1. andesitic magma
an active area of volcanoes due to a consistent source of magma in the asthenosphere
2. basaltic magma
volcano formed of volcanic rock and ash; erodes quickly
3. cinder cone volcano
magma that has low viscosity and low silica and gas content; eruption is non-explosive
4. composite volcano
volcano that is tall and steep; formed of lava and volcanic debris
5. Hawaiian eruption
non-explosive or very mild volcanic eruption
6. hot spot
the most powerful, explosive type of volcanic eruption
7. plinian eruption
magma that is a mix of basaltic and rhyolitic; eruption may or may not be explosive

Answer 1

Here is the matching for the items in the left column with those in the right column:

1. andesitic magma - magma that is a mix of basaltic and rhyolitic; eruption may or may not be explosive
2. basaltic magma - magma that has low viscosity and low silica and gas content; eruption is non-explosive
3. cinder cone volcano - volcano formed of volcanic rock and ash; erodes quickly
4. composite volcano - volcano that is tall and steep; formed of lava and volcanic debris
5. Hawaiian eruption - non-explosive or very mild volcanic eruption
6. hot spot - an active area of volcanoes due to a consistent source of magma in the asthenosphere
7. plinian eruption - the most powerful, explosive type of volcanic eruption
