When two tectonic plates collide along a fault line, they often cause earthquakes. However, since one plate will push the other up to make way, this will also cause the arising of mountains. Mountains will slowly grow in size if the plates continue to rub against one another.

One thing that makes answering this a bit tricky is determining how to measure. The Moon has no "sea level", so the comparison that makes the most sense is to measure from the highest point to the lowest. On the Moon, this is a bit over 18km. On Earth, Mt. Everest is at nearly 9km above sea level, and the deepest point is the Mariana Trench at not quite 11km below sea level, for a total difference of well over 19km. By that standard, the Earth's mountains are taller than the Moon's mountains. However, the difference is only about 10%, and the Earth is a lot more than 10% bigger than the Moon, so proportionally speaking the Moon's mountains are taller.
God made some higher than others!
Gravity on the moon is one sixth of gravity on the earth, so mountains on the moon can be much taller. Mountains on earth are eroded by wind and water, but on the moon mountains are not eroded.
It is that the mountains also are big by growing taller and taller for to be healthy the animals too for the beautiful mountains.

Because mountains are taller than us
Rocky Mountain is taller than Appalachian Mountain. But they are both the tallest mountains in North America
The ground heaps up.
Because they are higher up in the sky. The taller the mountains are, the colder they get.
The west side has more mountains that are also taller, and wider in range then the Appalachian mountains
Yes, Mount Everest is taller than the Rocky Mountains, standing at 29.028ft or 8.848m high it is the highest mountain in the world.
Monte Rosa at 15,203 feet above sea level is the talllest in Switzerland and is taller than any Colorado Mountain.
Seventeen mountains in Alaska are taller. Only one, Mount Whitney, in the lower 48 is taller.
