Why is the Northern Hemisphere more polluted?

Why is the Northern Hemisphere more polluted?

The Northern Hemisphere tends to have more polluted air than the Southern Hemisphere because it has more cities, more population in those cities on average and more industry. And each hemisphere’s air masses tend to stay segregated from one another.

Where is the least polluted place on Earth?

The Cleanest Countries

• Sweden. The least polluted country is Sweden with overall score of 2.8/10. The amount of carbon dioxide is 3.83 tonnes per capita per year, and the concentrations of PM2.
• Finland and France. Finland shares second place with France with a score of 3.5/10.

What is the main difference between the northern and Southern Hemisphere?

The Northern Hemisphere contains North America, the northern part of South America, Europe, the northern two-thirds of Africa, and most of Asia. The Southern Hemisphere contains most of South America, one-third of Africa, Australia, Antarctica, and some Asian islands.

Why is there less ozone in the Southern Hemisphere?

In the Southern Hemisphere, the South Pole is part of avery large land mass (Antarctica) that is completely surrounded by ocean. This chlorine and bromine activation then leads to rapid ozone loss when sunlight returns to Antarctica in September and October of each year, which then results in the Antarctic ozone hole.

Which hemisphere is more polluted?

northern hemisphere
The atmosphere is much more polluted in the northern hemisphere than in the southern hemisphere. This is because, while the southern hemisphere mainly consists of oceans, the northern hemisphere includes the large continents of Asia, Europe and North America and their industry and traffic.

Which hemisphere has the most pollution?

Findings suggest aircraft emissions may alter the stratosphere at mid-high latitudes. Scientists have long recognized that, on average, air pollution in the troposphere, or lower atmosphere, is worse in the Northern Hemisphere than in the Southern Hemisphere.

What city has no pollution?

Least polluted: Zurich, Switzerland.

Why the Southern Hemisphere is better?

Southern Hemisphere climates tend to be slightly milder than those at similar latitudes in the Northern Hemisphere, except in the Antarctic which is colder than the Arctic. This is because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land.

What is different about the Southern Hemisphere?

During the day in the Northern Hemisphere, the sun will rise to its maximum point at a southerly position, because it will go with the direction of the equator (south). In the Southern Hemisphere, the opposite occurs, as the sun rises to its maximum point in a northern direction.

Why is there a difference between the Southern Hemisphere and the northern hemisphere with respect to ozone depletion?

The losses in the Southern Hemisphere are greater than those in the Northern Hemisphere because of the Antarctic ozone hole. Long-term changes in the tropics are much smaller because reactive halogen gases are less abun- dant in the tropical lower stratosphere. Q13: How large is the depletion of the global ozone layer?

Why is there more ozone depletion over Antarctica?

Antarctic ozone hole The Antarctic is much colder than the rest of the planet and experiences consistent strong winds. The Antarctic ozone hole develops in August and dissipates in late November when warmer weather and ozone rich air from outside the polar vortex disrupts the chemical reactions causing ozone depletion.
