Why Do Mountains Glow at Night?

Imagine you're playing with a flashlight in the dark. When you shine it on your hand, it glows, that's because light is bouncing off your skin and into your eyes. Some mountains are like that when they get hit by moonlight or sunlight at night. The rocks and soil inside them act like tiny mirrors, sending the light back to us, making the mountain look bright in the dark. This glowing effect is called mountain glow.
