Understanding Earth's Seasons

What is the primary cause of seasonal changes on Earth?

• The Earth's rotation speed

• The Earth's axial tilt

• The Earth's magnetic field

• The Earth's distance from the Sun

How long does it take for the Earth to complete one revolution around the Sun?

• 365 days

• 30 days

• 24 hours

• 12 months

What is the angle of the Earth's axial tilt?

• 15.5 degrees

• 23.5 degrees

• 30 degrees

• 45 degrees

Which latitude is located at 23.5° in the Southern Hemisphere?

What phenomenon occurs at the Arctic Circle during the Summer Solstice?

• 24 hours of darkness

• 24 hours of daylight

• Equal day and night

• Longest night of the year

How does the Earth's tilt affect ocean temperatures?

• It causes the oceans to freeze

• It leads to warming and cooling of oceans

• It causes constant ocean temperatures

• It has no effect on ocean temperatures

What role do convective currents play in Earth's climate?

• They have no impact on climate

• They stabilize temperatures

• They cause earthquakes

• They move energy around the atmosphere

What is the result of warming oceans on the atmosphere?

• Evaporation of moisture

• Decreased humidity

• Increased rainfall

• Cooling of the atmosphere
