00:00NATURAL ENVIRONMENT

00:04Our solar system consists of the sun and eight planets.

00:12The sun is a star at the center of our solar system.

00:18The earth and the other planets move around the sun.

00:26Three quarters of the earth's surface is covered by water.

00:32Wake up! It is day.

00:36Did you sleep well?

00:38Do you know that you went for a ride?

00:41No?

00:42Well, the earth is in a constant state of movement.

00:47It keeps moving slowly around the sun.

00:51As you are on the earth, you too are moving with it.

00:58The sun gives heat and light to the turning earth.

01:03The natural things on the surface of the earth are mountains, hills, valleys, deserts, soils, rocks, rivers, lakes, seas and oceans.

01:23A mountain or hill is a piece of land.

01:30It rises up above the land around it.

01:35A hill is smaller than a mountain.

01:39A valley is a narrow piece of land between two hills.

01:45Sometimes there is a river flowing through the valley.

01:49A desert is a dry land made up of sand.

01:54Soil is made up of tiny bits of rock.

01:58Rocks are of many shapes, sizes and colors.

02:03Marble, slate and granite are some of the rocks.

02:09Iron is found in the earth.

02:12It is mixed with other metals to get steel.

02:17I am made from iron.

02:20We are all made from steel.

02:25We are precious stones and metals.

02:28We shine, we flash, we sparkle.

02:33You get us all from the earth.
