Pits are small, hollow spaces or depressions found in various contexts. In nature, they can refer to holes in the ground, such as those made by animals or natural erosion. In agriculture, pits are often used for planting seeds or storing crops. In the context of fruit, a pit is the hard seed found in the center of certain fruits like cherries, peaches, and plums. These pits protect the seed inside, which can grow into a new plant if conditions are right. Pits can also refer to the small cavities in bones or other materials.
