14．The giraffe is the tallest modern land animal．It can be over 5.5meters tall．Its neck alone may be 1.9meters long．Yet the giraffe has only seven bones in its neck，the same number as in the humans'．Even a small bird has many more bones in its neck than a tall giraffe．Each bone in a giraffe's neck is very long，while the bones in a human's neck are short．That makes the difference．A female giraffe gives birth to one baby at a time．The baby，called a calf，is about 1.9meters tall at birth．By the age of eight it is full-grown．The giraffe eats mostly leaves．Because it has a long neck，it can reach the high leaves on the trees．

13．A cloud is water drops or small ice in the sky．There are many kinds of clouds．Clouds are an important part of Earth's weather．
How Do Clouds Form？
The sky can be full of water．But most of the time you can't see the water near the ground．It is usually in the form of water vapor and it is too small to see．When warm air goes higher in the sky，it gets large and cools down．Cool air can't hold as much water vapor as warm air．Some of the vapor gets together in the air and forms a very small drop of water．When lots of these drops come together they become a cloud and then we can see it．
Why Do Clouds Turn Gray？
Clouds are made up of small water drops and small pieces of ice．The water and the ice look white in the sun light．If the clouds get thick enough of high enough all the light above does not make it through，then the clouds look gray or dark．Also，if there are lots of other clouds around，they look gray．
What Are Some Kinds of Clouds？
Clouds get their names in two ways．One way is by where they are in the sky．Some clouds are high up in the sky．Low clouds are near the ground．These clouds are called fog．Middle clouds are between low and high clouds．The other way clouds get their names is by their shapes．
What Makes Rain？
Most of the water in clouds is in very small drops．The drops are so light and they stay in the air．Sometimes those drops meet other drops．Then they turn into bigger drops and then they become too heavy．And finally they come down to Earth．We call the falling water drops"rain"．When the air is colder，the water may form snow．
Why Do People Study Clouds？
Clouds are important．Rain and snow are important for life on Earth．At night，clouds keep the ground warm．In the daytime，clouds can keep us cool．Studying clouds helps people better understand Earth's weather．People use many things to study clouds．
