Why? Because…

If you ask “Why?” I answer, “Because.” Let me show you.

Why does rain fall from clouds?

Because tiny little drops of water (droplets) crash together inside clouds,

making raindrops,

then the raindrops fall!

We ask “Why?” when we are confused. We do not understand something that happens. But we want to understand!

Why do we catch colds and get sick?

Because tiny germs,

usually a rhinovirus,

get into our bodies, when we breathe,

or when we touch something where germs are (like a doorknob).

When you ask “Why?” you want to know the cause of something.

Why do things fall down, and not up?

Because, as Sir Isaac Newton discovered,

objects are attracted to each other—and that’s called gravity.

The Earth is a very big object,

so little objects, like apples, fall down toward the Earth!

The words after “because” are an explanation. People like explanations.

Why do giraffes have such long necks?

Because they need to eat the leaves from tall trees!

Causes lead to effects. To explain an effect, state the cause.

Why do stalactites form in caves?

Because caves start out wet,

and water drips from the ceiling,

and there is just a little calcium carbonate in that water,

which builds up when the water drips!
