 Earth

What is Earth you ask. Well our planet earth is a huge rocky ball. It Is one of the nine planets that travel around the sun. From Space, Earth looks blue because seas and lakes cover nearly three – quarters of its surface. Our planet has hot deserts, steamy rain forests and freezing cold North and South poles. In some parts, the land rises to make high mountains. The outside of Earth is a thin shell of hard rock with soil and water on top. The shell is called the crust. Soil is made of tiny pieces of eroded, or worn down, rock mixed with dead plants. Plants get water and food from the soil, through their roots. Many animals live underground and make their homes in the soil. The Earth's crust, or surface is divided into enormous pieces called plates. These plates are always moving very slowly. When plates move apart, the hot, runny rock below them rushes up to the surface and a volcano erupts. The hot, runny rock that comes out of a volcano is called Lava. When plates bump or scrape against each other, earthquakes occur.
