As an element it considered dry and cold.
When compared to modern science's states of matter, it would represent solids.
At E2 we see Earth as the foundation, the base from which to build and operate a project. For the guests this is the least visible element since it is almost entirely behind the scenes yet without it nothing else works.
Our design section is part of Earth because we know that a comprehensive design anchors the project and sets the pace for the rest of the job.
Just as design serves as a foundation for fabrication and installation, control is the central point for the operation of the systems.
Since it deals with solids, our motion and animation section is also located here.
