The plane primitive creates flat surfaces using the geometry component with the type set to plane.

<!-- Textured plane parallel to ground. -->
<a-plane src="#ground" height="100" width="100" rotation="-90 0 0"></a-plane>

Parallelizing to the Ground

To make a plane parallel to the ground or make a plane the ground itself, rotate it around the X-axis:

<a-plane rotation="-90 0 0"></a-plane>
