The correct answer is: the Korean Peninsula was divided along the 38th Parallel after World war II.
Currently the border is moved slightly(rather to the north) and the border is know as the Demarcation line - it's also no longer straight, as it was when it was the 38th parallel.
Your answer is Fault Block Mountains
Fault Block Mountains are created when tectonic plates break apart bed rock. If you've ever seen a picture of Yosemite National Park that enourmous rock is a Fault Block Mountain.
Best Of Luck,

The correct answer is - plate tectonics.
The convection currents in the mantle, are having very high temperatures and very high pressures. Because of that, they managed to crack the crust, and thus divide the surface of the Earth in multiple peaces, or as we call them, tectonic plates. The very high pressure from bellow manages to push the tectonic plates in certain direction, and even though that movement is only a couple of cm per year, on the long term it has huge effects on everything on the planet.
There's few methods how governments can promote solutions for climate disruptions:
1. Strictly regulate carbon dioxide (CO2) and methane as air pollutants
2. Phaze in carbon taxes or fees
3. Place a cap on total human generated carbon dioxide and methane emissions
4. Increase subsidies to businesses that encourage energy efficient technology
