IS COMING FROM THOSE CLOUDS.

- SURE DOES, DON.

- [sighing] - MR.

CONDUCTOR, WHAT DO YOU KNOW ABOUT CLOUDS?

EVERYTHING?

- WELL, NOT EVERYTHING.

THAT'S WHY I LIKE TO EXPLORE-- SO I CAN LEARN MORE.

AND I DO LIKE CLOUDS, MISS TINY.

CLOUDS FORM WHEN AIR IS HEATED BY THE SUN.

THE HOT AIR RISES AND COOLS, MAKING WATER DROPLETS THAT COME TOGETHER TO FORM A CLOUD.

- SO ALL THE CLOUDS WE SEE ARE FULL OF WATER?

- YES, INDEED, DON.

CLOUDS ARE MADE OF BILLIONS OF TINY DROPLETS OR WATER OR ICE CRYSTALS THAT ARE SO LIGHT, THEY CAN FLOAT IN THE AIR.

- OH!

GAH!

[sighs] - SO THEN WHY DO THE CLOUDS MAKE RAIN?

- EXCELLENT QUESTION, SHINY.

- I AGREE, AND THE ANSWER IS SIMPLE.

WHEN A CLOUD BECOMES TOO HEAVY WITH SO MANY DROPS OF WATER, IT HAS TO RELEASE THEM, SO IT RAINS.

BUT WHAT ALWAYS FASCINATED ME ABOUT CLOUDS WERE THAT THERE ARE DIFFERENT KINDS.

VOILA!

DON'T THEY LOOK DIFFERENT FROM EACH OTHER?

- THEY DO!

- I NEVER NOTICED THAT.

- THESE ARE CALLED CIRRUS CLOUDS.

THEY'RE THIN, WISPY CLOUDS MADE MOSTLY OF ICE.

NEXT ARE THE STRATUS CLOUDS.

THEY ARE USUALLY GRAYISH AND LARGE, COVERING THE ENTIRE SKY LIKE A BIG FOG.

AND THESE THIRD CLOUDS ARE CALLED CUMULUS.

THEY ARE THE WHITEST AND PUFFIEST ONES.

- I SEE THOSE ALL THE TIME.

THEY REALLY LOOK LIKE THEY'RE MADE OF NOTHING.

- ACTUALLY, MR. LAMBEOSAURUS, CUMULUS CLOUDS ARE DEFINITELY MADE OF WATER.

YOU SEE, THEY CAN TURN INTO VERY DARK THUNDERSTORM CLOUDS AND PRODUCE A LOT OF RAIN.

[thunder rumbling] - OH, OKAY, I GET IT.

I WAS WRONG ABOUT CLOUDS.

THEY ARE MADE OF WATER OR ICE, AND RAIN DOES COME FROM THEM.

WE CAN HAVE THREE TEAMS.

I PICK STRATUS CLOUDS!

DAD, WILL YOU BE ON MY TEAM?

- YOU BET.

WE'RE THE SHINY STRATUS TEAM.

- I LIKE THOSE CIRRUS CLOUDS.

- ME TOO, A LOT.

CAN I BE ON YOUR TEAM?

- SURE, LILY.

- AND BUDDY AND I ARE TEAM CUMULUS.

- BUT, DAD, YOU'RE NOT ON A TEAM.

- BELIEVE ME, I'M FINE, LILY.

I'LL BE TEAM LARRY, WATCHING YOU ALL FIND YOUR CLOUDS.

- NOW WE HAVE TO REMEMBER WHAT OUR CLOUD LOOKS LIKE.

- JUST DO WHAT I DID AS A TROODON TOT.

I USED TO PLAY A CLOUD SPOTTING GAME TOO.

AND THE WAY I REMEMBERED WHAT THE CLOUDS LOOKED WAS BY DRAWING A PICTURE OF THEM.

MOTHER WOULD GIVE ME A LEAF AND A SMALL, POINTY STICK TO DRAW WITH.

all: GOOD IDEA!

- AND, IN FACT, HERE ARE LEAVES AND POINTY DRAWING STICKS FOR EACH OF YOU.

THERE YOU GO.

NOW YOU CAN DRAW YOUR CLOUD.

AND KEEP YOUR DRAWING WITH YOU TO LOOK AT LATER WHEN YOU'RE CLOUD HUNTING.

all: THANKS, MR.

CONDUCTOR!

- YOU KNOW, DADS, I THOUGHT IT WOULD BE FUN
