Scientists believe the earth is 4.6 billion years old. However, the mountains, valleys (山谷), hills, rivers, deserts and forests we see today are much younger than that. For example, Mount Qomolangma is about 60 million years old and the Amazon rainforest is only 10 million years old. The youngest sea in the world is the Baltic Sea, about 15,000 years old.
The earth is always changing because of volcanoes (火山), earthquakes (地震) and of course, wind and rain. Some of these changes are very slow and others are quick. Water and ice can make very great changes to our planet. For example, rivers of ice can cut through mountains and make lakes and deep valleys. Many volcanoes are under the oceans and sometimes they become new islands (岛屿).
It’s normal for our planet to change, but at the moment, scientists think it’s changing faster than usual. Some deserts are growing and many forests are getting smaller. The weather is getting wetter in some places and drier in others, and there are more big storms. Then the sea level will go on rising in the next hundred years. As a result, many cities will possibly be covered by water and many of the farming areas will be lost. Some island countries may disappear (消失) in the world.
These changes will bring great harm (伤害) to the planet. However, they can be beneficial to some people. For example, as the Arctic (北极) is getting warmer, some people in Greenland now own businesses and sell vegetables they grow on their land. That wasn’t possible in the far north 50 years ago. Farmers in Greenland like the warm weather and hope it will continue.
