What part of the volcano serves as the region under the surface of the Earth where hot molten magma is collected?

• B. main vent

• C. secondary vent

• D. magma chamber

Which part of the volcano is located at the top and is often the highest point of the volcano, sometimes forming a crater?

• Main vent

• Lava flow

• Summit of the volcano

• Magma chamber

Which of these volcanoes is typically the smallest in size and has a steep profile?

• Composite volcano

• Shield volcano

• Cinder cone

• Lava dome

Which of the following is TRUE about cinder cone?

• It is built from particles and blobs of solidified lava ejected from a single vent.

• Lava coming out from this volcano is not accompanied by pyroclastic materials.

• Lava blown out from this volcano breaks into small fragments solidify and fell as cinder around the vent.

• It is formed from viscous magma being erupted effusively onto the surface

  and then piling up around the vent.

What is the basis of classifying volcanoes as active or inactive?

• size of the base

• shape of the cone

• age of the volcano

• records of eruption

Which of the following statements is CORRECT?

• Active volcanoes do not have magma supply while inactive volcanoes have magma supply.

• Active volcanoes exhibit volcanic activity within the last 10 000 years while inactive volcanoes have no record of eruption.

• Inactive volcanoes are those that erupted recently and showing regular activity while active volcanoes exhibit no sign of volcanic activity.

• Inactive volcanoes exhibit sign of emissions of molten materials and gases

  while active volcanoes show no sign of emission
