Circulation Cells and Wind Patterns

The video explains the concept of circulation cells and their role in wind formation. It starts with the equator, where solar energy heats the atmosphere, causing hot air to rise and create areas with little wind known as doldrums. The air then moves to the troposphere and stratosphere, cooling and forming trade winds as it returns to the equator. The video also covers the formation of westerlies and easterlies, highlighting the three main circulation cells from the equator to the poles. These cells help distribute heat across the planet, although the system is not perfect due to temperature variations.

What is the primary cause of wind formation according to the video?

• Mountain ranges

• Human activity

• Circulation cells

• Ocean currents

Why is there little to no wind at the equator?

• The influence of ocean currents

• The Earth's rotation

• The presence of mountains

• The heating of the atmosphere causing air to rise

What happens to air as it rises into the atmosphere?

• It cools and condenses

• It evaporates

• It heats up and expands

• It remains at the same temperature

What are the trade winds?

• Winds that circulate around mountain ranges

• Winds that blow from the equator to the poles

• Winds that return to the equator after rising

• Winds that blow from the poles to the equator

Which winds are formed as air moves along the Earth's surface and heats up?

• Westerlies

• Polar winds

• Trade winds

• Easterlies

How many major circulation cells exist between the equator and the poles?

• Four

• Three

• Two

• One

What is the primary function of the wind belts on the surface of circulation cells?

• To move heat over the planet

• To influence human activity

• To create ocean currents

• To form mountain ranges

Why is the temperature not uniform across the planet despite the circulation cells?

• The Earth's rotation

• The presence of mountains

• The imperfect nature of the system

• The influence of human activity

What is the role of circulation cells in global heat distribution?

• They prevent heat from reaching the poles

• They move heat from the equator to the poles

• They have no role in heat distribution

• They concentrate heat at the equator

How does the Earth's temperature compare to other planets without similar heating systems?

• It is more uniform

• It is hotter

• It is colder

• It is more drastic
