The Southern Hemisphere is Colder, Stormier, and... Cleaner?

Which hemisphere generally has warmer average temperatures?

• The Northern Hemisphere

• The Southern Hemisphere

• Both hemispheres have the same average temperature.

• The temperature difference varies too much to generalize.

What is a major reason the Northern Hemisphere is generally warmer than the Southern Hemisphere?

• The Northern Hemisphere has more landmass, which warms up faster.

• Ocean currents, like the Atlantic Meridional Overturning Circulation, carry heat towards the North.

• The Earth's tilt causes the Northern Hemisphere to receive more direct sunlight.

• There are more active volcanoes in the Northern Hemisphere, releasing heat.

Why does the Southern Hemisphere experience more storm activity compared to the Northern Hemisphere?

• The Southern Hemisphere has more ocean, which generates more storms.

• The Northern Hemisphere has more mountains that can break up storms.

• The Earth's rotation causes storms to form more easily in the South.

• There is less pollution in the Southern Hemisphere, allowing storms to grow.

Why is the air in the Southern Hemisphere generally cleaner than in the Northern Hemisphere?

• The Southern Hemisphere has stronger winds that disperse pollutants more effectively.

• There are fewer industrial areas and less human population in the Southern Hemisphere.

• The Intertropical Convergence Zone prevents pollution from crossing the equator.

• The Southern Hemisphere has more forests that filter the air.
