Kewan Geography 11 Climate

What is the main reason why temperatures decrease with altitude?

• Wind speeds increase with height
• There is less vegetation at higher altitudes
• The atmosphere absorbs more longwave radiation from the earth than from the sun
• Air pressure increases with altitude

Which form of radiation does the Earth emit after absorbing solar radiation?

• Shortwave radiation
• Infrared radiation
• Microwave radiation
• Gamma rays

Why is the equator the most intensely heated area on Earth?

• It has the longest daylight hours
• It is closest to the sun
• The sun’s rays strike the surface more directly
• It has the lowest altitude

Why do the polar regions lose more heat than the equatorial regions?

• Because of the Earth's rotation
• Due to higher wind speeds
• Because the sun’s rays strike at an angle and pass through more atmosphere
• Due to more volcanic activity

How does a high albedo at the poles affect temperature?

• It causes more absorption of heat
• It causes more reflection of heat
• It causes more cloud formation
• It causes higher humidity

Which of the following causes the changing of seasons?

• Earth’s elliptical orbit
• Earth’s tilted axis and revolution around the sun
• Earth’s magnetic field
• Uneven heating of the oceans

Why does the equator experience 12 hours of day and night throughout the year?

• Because it rotates slower than other latitudes
• Because the Earth is flat at the equator
• Due to the Earth’s consistent rotation and position of the sun
• Because of the lack of seasons

Which date marks the spring equinox in the Southern Hemisphere?

• 2025-03-21 00:00:00
• 2025-06-22 00:00:00
• 2025-09-23 00:00:00
• 2025-12-22 00:00:00

What is the summer solstice date in the Southern Hemisphere?

• 2025-06-22 00:00:00
• 2025-03-21 00:00:00
• 2025-09-23 00:00:00
• 2025-12-22 00:00:00

Which of the following best describes how ocean currents influence climate?

• Ocean currents increase wind speeds globally
• Warm and cold currents transfer heat and affect coastal temperatures
• Ocean currents raise the land elevation
• Ocean currents create deserts near the equator
