Question

many scientists don’t believe that venus is currently volcanically active. they argue that the planet’s extreme atmospheric pressure makes such activity very unlikely. also, they believe that the channels in the planet’s surface, which are signs of lava flow from volcanic activity, were created by ancient eruptions as opposed to current eruptions. still, planetary geologist james head claims that venus may be experiencing ongoing volcanic activity. what finding, if true, would most directly support head’s claim? choose 1 answer: a remote sensing data reveals that venus’s atmospheric conditions, particularly its pressure and temperature, have changed very little over the last several decades. b high - resolution radar images from a recent nasa mission reveal new channels on venuss surface that were absent in previous surveys. c new radiometric dating data suggests that volcanic activity on venus may have occurred tens of thousands of years ago, as opposed to hundreds of millions of years ago as previously believed.

Explanation:

Head claims Venus has ongoing volcanic activity. New surface channels not seen before could be signs of recent lava flow from active volcanoes, supporting his claim. Option A shows stable atmosphere which doesn't support ongoing activity. Option C only gives a more recent past - time for volcanic activity, not current activity.

Answer:

B. High - resolution radar images from a recent NASA mission reveal new channels on Venus's surface that were absent in previous surveys.
