Scientists observe large, gently sloping mountains and vast, flat plains on Venus using radar. By comparing these features to similar ones on Earth, what is the most likely conclusion about Venus's geological history?

Its surface was primarily shaped by wind and sand erosion.

It experienced significant geological activity involving molten rock.

The planet was once covered by a global ocean that has since evaporated.

Its crust is broken into many tectonic plates that are constantly shifting.

What fundamental principle allows scientists to use Earth as a reference to understand the geology of other rocky planets like Venus?

All rocky planets have the same atmospheric composition.

The laws of physics and chemistry are universal and produce similar geological features under similar conditions.

All planets in the solar system formed at the exact same time from the same materials.

Earth is the only planet with a known, complete geological history.

the movement of crustal plates.

the solidification of magma or lava.

the impact of asteroids and comets.
