Terrakinesis would be the ability to manipulate the earth. I can't think of anything in that regard that would be a kinesis specifically, but almost all kinesis practices are some form of telekinesis.
I would suggest practicing giving energy to plants to help them grow. That could be a form of terrakinesis. The opposite, taking energy away, could also be a form. Basically helping things grow or stopping it. Moving the tectonic plates to cause earthquakes may also count, but I really don't see any of it as necessary. Growing things, absolutely, killing weeds, definitely, everything else doesn't really have a purpose and would take tons of practice and energy.
