Question

volcanoes quick check
which of these are features of most stratovolcanoes? (1 point)
○ steep sides near the top with thick, slow - moving lava
○ gentle slope near the top with thin, quickly flowing lava
○ steep sides near the base with sudden, violent eruptions
○ gentle slope near the base with somewhat quiet eruptions

Explanation:

Stratovolcanoes (composite volcanoes) typically have a gentle slope near the base (due to layers of lava and ash building up over time) and often have somewhat quiet eruptions compared to more explosive types, though they can have explosive phases too. The other options misdescribe their features: steep sides near top with thick lava is incorrect (they have steep upper slopes but thick lava is more for shield volcanoes in a way, and stratovolcanoes' lava is viscous but the slope description here is wrong), gentle slope near top with thin lava is wrong (upper slopes are steep), and steep sides near base with sudden violent eruptions is incorrect (base slope is gentle).

Answer:

D. gentle slope near the base with somewhat quiet eruptions (Note: Assuming the options are labeled A, B, C, D in order as given. If the original had different labels, adjust accordingly. Based on the options provided, the correct one is the last option: "gentle slope near the base with somewhat quiet eruptions")
