Vertical motions on Venus

Vertical motions on Venus

Fig. 7.24 . Some of the surface features on Venus have been formed by vertical, up and down motions driven by hot material welling up from the planet's interior. When rising bubbles of hot rock press against the crust, they can form domed, cracked features known as coronae. Larger plumes support volcanic rises on Venus, while sinking regions can lead to mountain formation.
