A trench is like a really long, narrow groove in the ground. Imagine a big line dug into the earth, almost like a giant is using a spoon to scoop out a line of dirt. These grooves, or trenches, can be very deep, like a big, long hole that stretches far across the land.
Think of a trench like a river without water. Instead of flowing water, there’s just a path where the earth has been moved away. Trenches can be used for different things, like hiding soldiers during a battle or laying pipes underground to carry water or wires.
A trench is also like a big wrinkle in the ground. Just like when you scrunch up your blanket and it makes lines on your bed, the earth sometimes gets scrunched up and forms trenches. These can be found in nature, like the ones under the ocean called ocean trenches, which are some of the deepest parts of the earth.
Finally, imagine a trench as a secret pathway. Just like how you might dig in the sand to make a path for your toy cars, trenches are paths dug into the earth, sometimes to help people move things or to protect them from danger.
