Planets: There are 8 planets in the solar system. Earth is the third planet from the Sun.
Other celestial bodies: Includes moons, asteroids, comets, and meteoroids.

2. Shape of the Earth

Earth’s Shape: Earth is an oblate spheroid, slightly flattened at the poles and bulging at the equator.
Proof: Photographs taken from space confirm the round shape of the Earth.

3. Globes and Maps

Globe: A model of Earth, showing its shape and surface.
Map: A flat representation of Earth. It can show large or small areas.
Types of maps: Physical, political, and thematic maps.
