Regarding the first, it seems the point of the technique is to turn earth into a more loose, less structurally sound nature. Would this technique work through gravity, where the earth is required to pre-exist in a diagonal/slope, or is it like you said, where the tehcnique automatically creates a wall that is then turned loose? I liek the concept of being a technique that breaks down earth.
Nope, people usually die by drowning in their own swamps."

"Similar to the one we just covered, manipulate your Earth chakra to create a wall of Earth. You will then slam your hands onto the ground, and cause a landslide to occur. Pretty simple, and can be directed."

Damage points: N/A
Description: The user slams his hands on the ground and lowers or raises the ground in the surrounding area at high speeds, allowing them to create giant holes in the ground or avoid attacks. The size of the affected area as well as the depths that it is lowered to is up to the user and rasing earth can be done up to 20 meters tall creating a small cliff or they can create trenches that can be as deep as 20 meters. Other than being moved below ground relative to the surrounding surface the terrain is not altered, plant life and people retaining their same positions.
"Lastly, this technique works by slamming your hands onto the ground as you focus your Earth based chakra. This allows you to raise or lower the earth up to 20 meters. This can be done to raise you up, lower the opponent, create a gorge, etc. Pretty useful."
The second is simple enough, loads of spikes.
The third, can I make the gorge/plateu have any shape I want, or is it limited to the basic circular/square shape? Like, could I do a "U" shape, where I create a bent wall all around me, protect me from an attack, for example? Could I raise a plateau in the chape of a doughnut, with my opponent in the middle?
