Question

select the correct answer.

this image of the volcano sapas mons on venus is based on images taken by the soviet spacecraft venera 13 and venera 14. which of these events explains the presence of the volcano?

space objects collided with venus.
flowing rivers eroded a hole through venuss crust.
magma from venuss mantle erupted as lava.
excessive heat from the sun scorched the area.

Explanation:

Identify the geological feature

The question asks about the presence of Sapas Mons, which is explicitly identified as a volcano on Venus.

Analyze the mechanism of volcanism

Volcanoes are formed when molten rock (magma) from a planet's interior (mantle) rises and erupts onto the surface as lava, cooling to build up volcanic structures.

Evaluate the given options

• Space objects collided with Venus: This describes impact cratering, not volcanism.
• Flowing rivers eroded a hole through Venus's crust: Venus does not have liquid water rivers due to its extreme temperature, and erosion does not create volcanoes.
• Magma from Venus's mantle erupted as lava: This correctly describes the volcanic process that forms a volcano like Sapas Mons.
• Excessive heat from the Sun scorched the area: Solar heating affects surface temperatures but does not create volcanic mountains.

Answer:

• Space objects collided with Venus.
• Flowing rivers eroded a hole through Venus's crust.
• Magma from Venus's mantle erupted as lava. (Correct answer)
• Excessive heat from the Sun scorched the area.
