The document discusses why we experience day and night and how it relates to the seasons. Day and night occur as the Earth spins on its axis, causing different parts of the planet to face toward and away from the sun. During summer in a particular hemisphere, there is a longer period of daylight due to the tilt of the Earth. We can see the moon at night through the reflection of sunlight, while the sun appears to disappear at night because the Earth's rotation prevents it from illuminating all areas at once.

1. DAY AND
NIGHT
By abdulbari

2. WHY DOWE HAVE DAY
AND NIGHT?
• We get day and night because the
Earth spins (or rotates) on an
imaginary line called its axis.
different parts of the planet are
facing towards the Sun and others
away from it. So it takes 24 hours
for the earth to spin around its axis.

3. WHAT ISTHE EFFECT BETWEEN DAY AND NIGHT IN
DIFFERENT SEASONS?
• When the tilt of Earth is toward the
Sun in a particular hemisphere,
there is a longer length of day and
the season is summer. When both
hemispheres are receiving the same
amount of sunlight, the length of day
and night is equal. This occurs in
autumn and spring.

4. WHY CANWE SEETHE
MOONAT NIGHT?
• The moon has an orbit around
the earth. we can see it at
night because of the reflection
of the sun’s rays and energy
that bounce back to the earth.
This is what gives the moon
the brilliant white glow.

5. WHY CAN’T WE SEETHE
SUN AT NIGHT?
• What makes the Sun seemingly
disappear at night is the Earth’s
rotation or turning motion. While the
Sun continuously shines on the
Earth, it cannot provide sunlight to
all parts of the Earth at the same
time.

6. QUESTI
ONS
• WHY DO WE HAVE DAY AND NIGHT?
• WHAT IS THE EFFECT BETWEEN DAY AND
NIGHT IN DIFFERENT SEASONS?
• WHY CAN WE SEE THE MOON AT NIGHT?
• WHY CAN’T WE SEE THE SUN AT NIGHT?

7. SUMM
ERY
• We have day and night because the earth spins on its axis.
• The effect between day and night in different seasons is when the
tilt of Earth is towards the sun in a particular hemisphere.
• We can see the moon at night because of the reflection of the
sun’s rays and energy that bounce back to the Earth.
• We can’t see the sun at night because the Earth rotates while the
sun shines on it, so it cannot provide sunlight to all parts of the
world
