Terrace (earthworks)

Have you ever seen steps going up a big hill or mountain? That's kind of what a terrace is! People carve flat spots, like giant steps, into the sides of hills. These flat spots are called terraces. They are made so farmers can grow food, like rice, in places that are usually too steep. It's like building a special playground for plants on a mountain!

Long, long ago, people figured out a super smart way to farm on hills. Instead of trying to grow plants on a slippery slope, they dug out flat areas. This made it much easier to plant seeds and water them. It also stopped the soil from washing away when it rained, which is a big problem on steep hills. These clever farmers invented terracing to make the most of the land.

Terraces have amazing superpowers! First, they stop the soil from washing away when it rains. This is called preventing erosion. Second, they help keep water where it's needed for the plants, especially for thirsty crops like rice. Imagine a staircase holding water! This means farmers can grow food even in places that don't get a lot of rain.

Some of the most famous terraces are in the Philippines. They look like giant, green staircases climbing up the mountains, and they are thousands of years old! These rice terraces are so special that they are a UNESCO World Heritage Site. This means they are protected because they are important to the whole world. They show how smart and hardworking people can be.
