Imagine you're playing with legos, and you build a tall structure with many different pieces stacked on top of each other. This is kind of like a tower!
A tower is a big, tall structure usually made out of a lot of materials like steel, concrete, brick or wood. It's shaped like a long skinny rectangle that goes up really high in the sky. You can usually see the top of a tower from far away because it's so tall.
Some towers are used for different things depending on where they're located. For example, some are used for communication and have antennas or satellite dishes at the top to help send messages or phone calls. Other towers are used for energy, like wind turbines or electricity transmission towers with wires on top that carry electricity. Some towers are just used for fun or for observation, like the Eiffel Tower in France, which is a popular tourist attraction!
Overall, towers are really amazing structures that help us communicate, generate energy, and enjoy beautiful views from up high!
