Earth, Sun and The Moon
Introduction
Celestial Connections
The Sun, Moon, and Earth interact 
in ways that shape our daily lives. 
Their movements create day and 
night cycles, seasons, and 
eclipses.
Scientific Understanding
We'll explore Earth's rotation and 
revolution. These motions explain 
why the Sun moves across the sky 
and how seasons occur.
Cultural Significance
Celestial events hold importance 
across cultures. Both ancient and 
modern scientists have 
contributed to our understanding.

Rotation of the Earth
Axis of Rotation
Earth spins on an 
imaginary line through 
the North and South 
Poles.
24-Hour Cycle
One complete rotation 
takes approximately 24 
hours.
Day and Night
This spinning motion creates our cycle of day and 
night.

Direction of Earth's Rotation
Counterclockwise Motion
When viewed from above the North Pole, 
Earth rotates counterclockwise. This west-to-
east motion is constant.
Though the Sun appears to move across our 
sky, it's actually Earth's rotation creating this 
illusion.
The Sun appears to rise in the east, move 
across the sky, and set in the west due to 
Earth's rotation.

Day and Night Cycle
In India, eastern regions see sunrise first because they face the Sun earlier during Earth's rotation.
Sunrise
As Earth rotates, regions face 
the Sun and experience sunrise.
Midday
When directly facing the Sun, 
regions experience midday.
Sunset
As regions rotate away from the 
Sun, they experience sunset.
Night
The side facing away from the 
Sun experiences darkness.
