Flashcards: Seasons why they happen

What causes the seasons?

The tilt of Earth's axis combined with its orbit around the Sun causes seasons.

What is Earth's axial tilt?

Earth's axis is tilted at approximately 23.5 degrees, affecting sunlight distribution.

True or false: Seasons are the same all over the world.

False, because different regions receive sunlight differently due to Earth's shape and tilt.

Difference between summer and winter.

In summer, the hemisphere is tilted toward the Sun, receiving more sunlight. In winter, it's tilted away.

Fill in the blank: The __________ causes day length to change.

tilt of Earth’s axis affects how long days last during different seasons.

How does orbit affect seasons?

As Earth orbits the Sun, different parts face the Sun more directly, causing seasonal changes.

What happens during equinoxes?

During equinoxes, day and night are approximately equal in length, marking spring and fall.

True or false: Summer is hotter because Earth is closer to the Sun.

False, because summer heat is due to the tilt of the axis, not distance from the Sun.

What is the significance of solstices?

Solstices mark the longest and shortest days of the year, influencing climate and ecosystems.

How do seasons affect weather?

Seasons influence temperature and precipitation patterns, impacting agriculture and ecosystems.

Comparison: Northern Hemisphere vs Southern Hemisphere seasons.

When it's summer in the Northern Hemisphere, it's winter in the Southern Hemisphere.

What is a revolution in terms of Earth?

Revolution refers to Earth's full orbit around the Sun, taking about 365.25 days.
