A mountain is a mass of land that is taller than its surroundings. While there is no technical definition between the two, a mountain is generally regarded to be much larger than a hill.
All mountains, at every elevation, have limestone deposits reflecting that they were once under seawater. The Great Flood accounts well for the presence of this limestone and the smooth, eroded surfaces found on some mountains.
