Wind Patterns and Atmospheric Effects

The video, led by science teacher Tim Martin, explores the movement of air in Earth's atmosphere and its impact on global wind patterns. It begins with a review of energy sources, primarily the Sun, and how they drive convection cycles. The video explains how these cycles create wind patterns, including Hadley, polar, and Farrell cells. It also covers the Coriolis effect's role in bending surface winds and identifies key zones like the doldrums and horse latitudes. The video concludes by highlighting the importance of understanding these patterns for weather forecasting and climate studies.

What is the primary source of energy that drives the movement in the Earth's atmosphere?

• The Earth's core

• The Sun

• The Moon

• Ocean currents

What happens to air as it warms and rises near the equator?

• It becomes denser and sinks

• It expands and rises

• It cools and contracts

• It remains stationary

Why do surface winds appear to bend as they move across the Earth?

• Due to the Earth's magnetic field

• Because of the Coriolis effect

• Because of ocean currents

• Due to gravitational pull

Which convection cell is located between 0 and 30 degrees latitude?

• Ferrel cell

• Polar cell

• Hadley cell

• Equatorial cell

What is the name of the wind pattern that occurs between 30 and 60 degrees latitude?

• Doldrums

• Polar easterlies

• Westerlies

• Trade winds

What is the area of very little surface wind around the equator called?

• Trade winds

• Polar front

• Doldrums

• Horse latitudes

What is the primary characteristic of the horse latitudes?

• Sinking air and little wind

• Constant rain

• Strong winds

• Rising air and strong wind

Which wind pattern is responsible for carrying early explorers from the Americas back to Europe?

• Southeast trade winds

• Polar easterlies

• Northeast trade winds

• Westerlies

What is the term for the effect that causes winds to bend due to Earth's rotation?

• Coriolis effect

• Magnetic effect

• Thermal effect

• Gravitational effect

What is the name of the zone where winds converge at the equator?

• Westerlies

• Intertropical Convergence Zone

• Horse latitudes

• Polar front
