The New Forest is a big area of land in the south of England that has lots of rocks, soil, and trees. It is called a forest because there are so many trees there, but it's not like a jungle or rainforest with lots of big animals. Instead, there are lots of cute little animals like ponies and rabbits.
The New Forest was formed a long, long time ago when the earth was really different. There were lots of volcanoes and earthquakes which made the ground move and change. The rocks on the surface of the ground got pushed, pulled, and mixed up by the movement of the earth's crust.
Over millions of years, the rocks in the New Forest turned into different shapes and sizes. Some of them are hard and shiny like quartz, and some are softer and squishier like clay. There are also lots of hills and valleys that were made by rivers and glaciers moving across the land.
All the different types of rocks and soils in the New Forest are really important because they provide homes and food for the plants and animals that live there. Some trees need specific types of soil to grow properly, and different animals like different types of rocks to live on or under.
So, in summary, the New Forest is a big area of land with lots of rocks, soil, and trees that were formed a long time ago by volcanoes and earthquakes. The rocks and soils are important for the plants and animals that live there to survive.
