Why does our Voice Echo on Hills? | #aumsum #kids #shorts #science?

When you shout on a hill, your voice comes back to you like a bouncing ball.

Imagine you're playing with a ball on a hill. You throw the ball down, and it rolls toward the bottom, but then it bounces back up! That’s what happens with your voice. When you shout, the sound waves travel through the air, go down the hill, and hit the other side, just like the ball hits the ground. Then they bounce back to you, making your voice seem like it's coming from two places at once.

Think of the hill as a big mirror for sound. Just like light bounces off a mirror and comes back to you, sound waves bounce off the hill and come back to your ears.

If you shout on a quiet day, the echo is loud and clear, it's like the hill is shouting back with you! But if it’s noisy or windy, the echo might be softer or mixed up, just like when you're playing hide-and-seek and someone calls out from behind a tree.
