Seasons and the Sun

What is the imaginary line the Earth spins on?

• Equator
• Tropic of Cancer
• Axis
• Meridian

What two factors combine to create the yearly pattern of seasons on Earth?

• Earth's rotation and the moon's orbit.

• Earth's tilt on its axis and its orbit around the sun.

• The sun's temperature and Earth's distance from the sun.

• The amount of daylight and the Earth's magnetic field.

What conditions are experienced by a hemisphere when it is tilted towards the sun?

• Cooler temperatures, shorter days, longer nights.

• Warmer temperatures, longer days, shorter nights.

• Moderate temperatures, equal day and night length.

• Heavy rainfall, strong winds, and cloudy skies.

What type of sunlight does a hemisphere receive when it is tilted away from the sun, and what are the resulting conditions?

• Direct sunlight, resulting in warmer temperatures and longer days.

• Indirect sunlight, resulting in warmer temperatures and shorter days.

• Indirect sunlight, resulting in cooler temperatures and shorter days.

• Direct sunlight, resulting in cooler temperatures and longer nights.

Why are temperatures more moderate during spring and autumn?

• The Earth is closer to the sun during these seasons.

• The Northern Hemisphere is neither tilted towards nor away from the sun, receiving an equal amount of direct sunlight.

• The Northern Hemisphere is receiving more direct sunlight than the Southern Hemisphere.

• Increased cloud cover blocks direct sunlight during these times.

So what does cause the seasons?

• The distance from the Earth to the Sun changes throughout the year.
• The phases of the Moon influence the seasons.
• The rotation of the Earth on its axis causes the seasons.
• The tilt of the Earth's axis and its orbit around the Sun cause the seasons.
