Zendikar as a plane/planet/world is characterized by "The Roil": a chaotic force that transforms the landscape without much warning. It is also probably responsible of the gravitational anomalies that are typical of many regions of Zendikar, the most famous being the Sky Ruin of Emeria, that you can see in the image I put as the logo of the group.

Add to this that many places in Zendikar are nearly pulsating with elemental power and probably every 4e DM would think it is at least all a great rift zone connected with the Elemental Chaos.
