Understanding the Variation in Daylight Throughout the Year

The video explains why daylight varies throughout the year, focusing on the Earth's tilted axis. In summer, longer daylight is due to the Earth's tilt towards the sun, while in winter, shorter daylight occurs when the Earth tilts away. The Earth's axis is tilted at 23.5 degrees, causing different parts of the world to experience varying daylight lengths. When the North Pole tilts towards the sun, the Northern Hemisphere enjoys more daylight, and when it tilts away, it experiences less.

Why do we experience longer days in the summer compared to winter?

• The moon reflects more sunlight in summer.

• The sun is larger in the summer.

• The Earth's axis is tilted, affecting daylight duration.

• The Earth is closer to the sun in summer.

What would happen if the Earth's axis were not tilted?

• There would be no seasons.

• All parts of the Earth would have equal daylight and darkness.

• The Earth would rotate faster.

• The sun would rise in the west.

What is the degree of tilt of the Earth's axis?

• 23 1/2 degrees

• 45 degrees

• 15 degrees

• 30 degrees

How does the tilt of the Earth's axis affect the Northern Hemisphere when the North Pole is tilted away from the sun?

• The Northern Hemisphere experiences more daylight.

• The Northern Hemisphere has no change in daylight.

• The Northern Hemisphere experiences constant daylight.

• The Northern Hemisphere experiences less daylight.

When the North Pole is tilted toward the sun, what happens in the Northern Hemisphere?

• It experiences constant darkness.

• It experiences more daylight.

• It experiences less daylight.

• It experiences no change in daylight.
