How Do Mountains Stay Upright for Millions of Years?

Mountains stay upright for millions of years because they are strong and balanced, just like a tower made of blocks.

Imagine stacking blocks on top of each other, like when you build a tall tower during playtime. If the blocks are placed carefully, the tower stands up straight. But if one block is too heavy or not lined up well, the whole tower might fall over.

Mountains are like these stacked blocks, except instead of blocks, they're made of rock layers that have been pushed together by forces deep inside the Earth. These forces act slowly, just like how you carefully place each block one after another.

Even though mountains are huge and seem very strong, they can still change over time. Sometimes, part of a mountain might wear down or break off, but because there's always something pushing them up from below, they stay standing for millions of years, like a well-built tower that keeps growing taller.
