Question

1. explore4_volcanoes take many forms, depending on the type of eruption that happens. match the eruption condition to the type of volcano it would likely form.

draggable item → corresponding item
lava alternates between high and intermediate viscosity → fissure eruption
a large explosion causes the volcano to collapse into its magma chamber → spatter cone
lava contains small pockets of gas, but they do not explode into fragments → stratovolcano
nonexplosive eruption flows from cracks in earth’s surface → shield volcano
lava has very low viscosity → caldera

Explanation:

• Lava alternates between high and intermediate viscosity: Stratovolcanoes form from lava with varying (high to intermediate) viscosity, leading to layered structures. So this matches "stratovolcano".
• A large explosion causes the volcano to collapse into its magma chamber: Calderas form when a volcano collapses after a massive explosion empties the magma chamber. So this matches "caldera".
• Lava contains small pockets of gas, but they do not explode into fragments: Spatter cones form from lava with gas bubbles that don't explode, allowing lava to spatter and build the cone. So this matches "spatter cone".
• Nonexplosive eruption flows from cracks in Earth’s surface: Fissure eruptions involve nonexplosive lava flowing from long cracks. So this matches "fissure eruption".
• Lava has very low viscosity: Shield volcanoes form from low - viscosity lava that flows easily, creating broad, shield - like structures. So this matches "shield volcano".

Answer:

• Lava alternates between high and intermediate viscosity → stratovolcano
• A large explosion causes the volcano to collapse into its magma chamber → caldera
• Lava contains small pockets of gas, but they do not explode into fragments → spatter cone
• Nonexplosive eruption flows from cracks in Earth’s surface → fissure eruption
• Lava has very low viscosity → shield volcano
