5 multiple choice 1 point
what geographic feature formed after krakatoas eruption?
a shield volcano
a rift valley
an underwater caldera

Explanation:

• Question 4:
• Yellowstone is a super - volcano and is still active.
• Mt. St. Helens had a major eruption in 1980 and is an active volcano.
• Vesuvius is also an active volcano (it had a famous eruption in 79 AD and has erupted since then).
• So, all of these volcanoes can erupt again.
• Question 5:
• Krakatoa's eruption in 1883 was extremely violent. The collapse of the volcano after the eruption led to the formation of an underwater caldera. A shield volcano is a type of volcano with a broad, gently - sloping shape formed by low - viscosity lava flows. A rift valley is formed by tectonic plate divergence, not by a volcanic eruption like Krakatoa's.

Answer:

• Question 4: C. They all can erupt again
• Question 5: C. An underwater caldera
