Understanding Seasons and Sunlight Effects

The video explains how the tilt of the Earth on its axis and its orbit around the sun cause the seasons. Using a flashlight and a wall, the video demonstrates the effects of direct and indirect sunlight. It shows how the angle of sunlight changes with Earth's tilt, affecting the intensity and distribution of sunlight, leading to different seasons. The video also illustrates how the northern and southern hemispheres experience opposite seasons due to Earth's tilt and orbit.

What causes the Earth to experience different seasons?

• The tilt of the Earth's axis

• The speed of Earth's rotation

• The shape of Earth's orbit

• The distance from the sun

In the demonstration, what does the flashlight represent?

• The moon

• A star

• A planet

• The sun

What happens to sunlight when it is direct?

• It changes color

• It focuses on a small area

• It becomes less intense

• It spreads over a large area

How does changing the angle of the flashlight affect the light on the wall?

• The light becomes more focused

• The light changes color

• The light spreads over a larger area

• The light becomes dimmer

What is the tilt of the Earth's axis?

• 45 degrees

• 30 degrees

• 23.5 degrees

• 15 degrees

When the northern hemisphere is tilted away from the sun, what season is it experiencing?

• Summer

• Winter

• Spring

• Autumn

What season does the southern hemisphere experience when it is tilted towards the sun?

• Spring

• Autumn

• Winter

• Summer

What happens to the sunlight when the Earth is not tilted directly towards or away from the sun?

• It becomes indirect

• It becomes more focused

• It spreads evenly

• It disappears

Why does the northern hemisphere experience summer when it is tilted towards the sun?

• It receives direct sunlight

• It is closer to the sun

• It has longer days

• It rotates faster

What is the relationship between the seasons in the northern and southern hemispheres?

• They both have summer at the same time

• They have no relation

• They experience opposite seasons

• They experience the same seasons at the same time
