There is a place on our earth where hot water and steam come up from under the ground．It is a large island in the Pacific Ocean．The island is North Island，in New Zealand．

The planet on which we live is a ball of very hot rock．It is a good thing for us that the outside shell is cold．If it were hot，no one could live here．What if our earth were only as big as an egg? Then the outside part would be as deep as the egg's shell．

The earth's shell has cracks in it in some places．In New Zealand this shell seems to have more cracks than in other places in the earth．There are spots where the ground is so hot that it burns the bottom of your shoes．In some places，hot water shoots into the air from time to time．At other points，you can see steam coming up from pools of hot water．

The people who live in these places make use of the heat coming from inside the earth．

Some of them cook in the hot pools They put food into a basket and place it in the water．Washing clothes is done in the same way．

Many people bring the hot water from below the earth into their homes．They do this by putting a pipe（管子）a hundred feet or more into the ground．In this way they get hot water and steam for cooking and washing，and for healing their homes．

For most of us，the heat under our feet is too far away to us．We must make our heat by burning coal，oil or gas．The people who get heat from inside the earth are lucky．It doesn’t take money to buy for coal，oil or gas．

Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.

And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.

We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.

These small pieces have been going round the sun ever since. They are the planets.
