Solid Ground

"Earthbend N" means "Target land you control becomes a 0/0 land creature with haste in addition to its other types. Put N +1/+1 counters on it. When it dies or is exiled, return it to the battlefield tapped under your control."

Earthbend doesn't give the land you control a color. As most lands are colorless, in most cases the resulting land creature will also be colorless.

If a land was animated by earthbend and would go to any zone other than the graveyard or exile, it will not be returned to the battlefield by the delayed triggered ability created by earthbend.

If a permanent you control would enter with a number of +1/+1 counters on it, it enters with that many plus one instead.

If the targeted land becomes an illegal target before the spell or ability that includes earthbend resolves, earthbend does nothing. If the spell or ability didn't have other targets, it won't resolve.

If two or more effects attempt to modify how many counters would be put on a permanent you control, you choose the order to apply those effects, no matter who controls the sources of those effects.

If you control multiple copies of Solid Ground, they each increase the number of +1/+1 counters put on a permanent you control by one.

The land will retain any other types, subtypes, or supertypes it previously had. It will also retain any mana abilities it had as a result of those subtypes. For example, a Forest that's turned into a creature this way can still be tapped for {G}.

You may target a land that is already a creature, perhaps because of a previous earthbend ability. The land will get the +1/+1 counters, gain haste, and have its base power and toughness set to 0/0.
