Choose an area of terrain no larger than 40 feet on a side within range. You can reshape dirt, sand, or clay in the area in any manner you choose for the duration. You can raise or lower the area’s elevation, create or fill in a trench, erect or flatten a wall, or form a pillar. The extent of any such changes can’t exceed half the area’s largest dimension. For example, if you affect a 40-foot square, you can create a pillar up to 20 feet high, raise or lower the square’s elevation by up to 20 feet, dig a trench up to 20 feet deep, and so on. It takes 10 minutes for these changes to complete. Because the terrain’s transformation occurs slowly, creatures in the area can’t usually be trapped or injured by the ground’s movement.
At the end of every 10 minutes you spend concentrating on the spell, you can choose a new area of terrain to affect within range.
This spell can’t manipulate natural stone or stone construction. Rocks and structures shift to accommodate the new terrain. If the way you shape the terrain would make a structure unstable, it might collapse.
Similarly, this spell doesn’t directly affect plant growth. The moved earth carries any plants along with it.

We have a large combat happening tonight. 3 armies on the field. Our side is caught in the middle at the base of a hill with the smaller force coming down the hill.
My druid is about to do some serious work to reshape the land to our advantage using this spell and Wall of Stone. in 2 hours of Move Earth, he will be able to create a 480ft long trench that is 20ft deep with a 20ft hill on our side. Then he'll use Wall of Stone to create a 10ft stone battlement across 100ft of that hill giving our archers a massive advantage against the army while the rest of us fight the smaller force coming down the hill.
Once we have dispatched them, we head up the hill and fight a 300 style battle slowly retreating up the hill.
It's Yester Hill, by the way. Ravenneans be damned. HA!
How do you reconcile that it can "erect or flatten a wall or form a pillar" but "This spell can’t manipulate natural stone or stone construction."?
This spell is used to shape dirt, sand, or clay, as it says in the first paragraph. It can manipulate walls or pillars made of those materials, but not walls or pillars made of stone.
Move earth would technically affect anything made of bricks because the mortar doesn't really qualify as stone. It's technically just sand and lime held together with dry clay. Two of those are counted under the affect of the spell, which contradicts itself because just about all stone structures would be made of stone bricks and mortar. Destabilizing the mortar and removing it would absolutely destroy any stone brick structure.
Possibly, but it seems pretty clear that this isn't the intended effect.
