Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why are mountains called water towers?

The Big Idea

Mountains are called water towers because they store water high up, like a tower. They hold winter snow and release it later as it melts. That water flows down to rivers, farms, and towns, all through the year.

Collect in Winter

Step one: mountains collect water in winter. Snow and rain fall on the high slopes, and the cold keeps it frozen. It is stored as snowpack and in glaciers, like water in a giant frozen tank.

Melt Slowly

Step two: the snow melts slowly. As the weather warms, meltwater trickles down into streams. It keeps flowing through spring and summer, just when plants and people need it most.

Rivers Share It

Step three: rivers carry the water downstream. Millions of people and animals depend on this steady supply. Mountains act like giant natural reservoirs, saving winter water for later.

A Closer Look

Let's take a closer look at a water tower! Winter snow piles up high. Glaciers store frozen water for many years. Warm weather turns it into meltwater. And rivers carry it far away.

Quick Facts

Quick facts! In western Canada, a big share of summer river water comes from melting snow. Rivers from mountains help farms and towns. Mountain water is saved for later, like a savings account. That is why protecting snow and glaciers matters.

Think Like a Scientist

Now, think like a scientist! Freeze a bowl of water into ice. Put the ice in a cup with a small hole, over a bowl. Watch it release water slowly, drip by drip. That is how mountains release water.

Outro

Mountains save water for later. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
