Earth's Seasons and Daylight Changes

The video explains why Norway experiences the midnight sun in summer and 24-hour darkness in winter. It discusses Earth's orbit, tilt, and how these factors affect daylight hours across different latitudes. An experiment with a globe and flashlight illustrates these concepts, highlighting the Arctic and Antarctic Circles' unique daylight patterns.

Why does the Sun remain visible at midnight in Norway during summer?

• Because of Norway's high altitude

• Due to the reflection of sunlight from the Moon

• Due to Earth's tilt and its position relative to the Sun

• Because Norway is closer to the Sun in summer

What is the angle of Earth's tilt that affects its orbit?

• 45 degrees

• 15 degrees

• 90 degrees

• 23.5 degrees

What is the significance of the Arctic Circle?

• It is the hottest place on Earth

• It marks the boundary where the Sun never sets during summer

• It is the center of Earth's orbit

• It is the line where the equator meets the poles

During the experiment, what does the flashlight represent?

• The Moon

• The Sun

• A star

• A planet

What happens to Norway during winter in terms of sunlight?

• It has 12 hours of sunlight and 12 hours of darkness

• It experiences 24 hours of darkness

• It experiences 24 hours of sunlight

• It has no change in sunlight

How does the length of daylight change as you move from the equator to the poles during the June solstice?

• It remains constant

• It decreases

• It increases

• It fluctuates randomly

What is the length of daylight at the equator during the June solstice?

• 12 hours of daylight

• 6 hours of daylight

• 24 hours of daylight

• 18 hours of daylight

During the December solstice, what happens to the length of daylight in the Southern Hemisphere?

• It becomes equal to the Northern Hemisphere

• It remains unchanged

• It becomes the shortest day of the year

• It becomes the longest day of the year

What causes the change in seasons on Earth?

• The tilt of Earth's axis

• The distance of Earth from the Sun

• The gravitational pull of the Moon

• The speed of Earth's rotation

What is the effect of Earth's tilt on the length of the day?

• It causes shorter days in summer and longer days in winter

• It causes longer days in summer and shorter days in winter

• It causes days to be the same length everywhere

• It has no effect on the length of the day
