Mountain Range

Imagine a super long line of bumpy hills, but way, way bigger! That's a mountain range. They are like a giant backbone for the Earth, made of many mountains standing close together. Sometimes they are separated by lower spots called passes or valleys. These ranges can be so long they stretch for thousands of miles, longer than your whole country!

Mountains don't just pop up! They are usually made when huge pieces of the Earth's crust, called tectonic plates, push against each other. It's like two giant rugs bumping together, causing the ground to wrinkle and fold upwards. Over millions of years, this slow-motion dance builds up massive mountains. Some mountains are also made by volcanoes erupting and piling up lava and ash.

Mountain ranges are like giant weather guards. When wind carrying rain or snow blows towards a mountain, it has to go up and over. As the air climbs, it gets cold and drops its water, making the mountain side wet. But on the other side, the air is dry and warm, creating a 'rain shadow' where it's much drier. This is why some places near mountains are super green and others are like deserts!

Guess what? Mountains aren't just on Earth! Other planets and moons have them too. Some are made of ice, like on Pluto, and some are even taller than Earth's biggest mountains, like on Venus. These space mountains show us that mountains are a common and amazing feature in our solar system, formed by different kinds of cosmic bumps and pushes.
