18. The Earth’s Data Earth our home in space is the third planet in the solar system. It is the only planet that has excellent condition to support life. 4.5 billion years- age of the Earth

19. Oblate spheroid- shape of the Earth, it a sphere with flat poles and a bulging equator.

20. MOTIONS OF THE EARTH ROTATION- is the spinning of the Earth in its axis. One complete rotation is equal to 24 hours. REVOLUTION- is the motion of the Earth in its orbit around the sun.

21. SPHERES OF THE EARTH 1) HYDROSPHERE- the dynamic mass of water that surrounds our planet. The hydrosphere includes the oceans, seas, streams, falls, rivers and lakes, locked as snow and glaciers.

22. 2. ATMOSPHERE- the blanket of gas that envelopes our planet. It contains the air that we breathe, protects us from the harmful solar radiation and insulates us from being frozen.

23. Nitrogen- most abundant gas in the atmosphere (78%) Oxygen- 2 nd most abundant gas in the atmosphere (21%) Other gases (1%) Carbon dioxide Argon Helium

24. ` 3. LITHOSPHERE- the solid part of the Earth that lies beneath the atmosphere and hydrosphere. The lithosphere includes the mountain, hills, plain, valley, rocks

25. 4. BIOSPHERE- comprises all the living components of the Earth. It includes plants, animals, birds insects, humans
