The Earth is an amazing planet!
Some places are very hot, like the areas
near the equator. Some are freezing cold,
like the North and South Poles. There are fields and mountains, rivers and seas, forests and deserts. The
highest mountain on Earth is over 8,800 metres above sea level. And the deepest part of the sea is more than 10,000 metres down.
The plants on Earth are wonderful in many different ways. The tallest trees in the world can reach over 100 metres in
height. The smallest plant is as small as a grain of rice.
The amazing planet
The Earth is home to millions of animals.
Some, like tigers and lions, live on land.
Other animals, like birds, enjoy the wide
open sky. Big blue whales call the sea
home, along with many amazing fish. From bears to birds, from butterflies to seahorses, animals make our planet
lovely and interesting.
And what’s more, the Earth provides us with
all the things we need, such as food, water,
air and energy. It is our home and the only
planet we know that supports life. Let’s explore,
learn about and take care of our home.
