Understanding the Atmosphere

The video explores the atmosphere, its layers, and the impact of human activities like CFCs on the ozone layer. It discusses the Montreal Protocol's success in reducing CFCs, the role of Earth's tilt in climate and seasons, and the effects of convection cells and the Coriolis effect on weather patterns. The video also covers ocean currents and the El Niño Southern Oscillation, concluding with a review of key concepts.

What is the primary function of stratospheric ozone?

• To regulate Earth's temperature

• To protect against harmful UV radiation

• To provide oxygen for breathing

• To support plant growth

What was the international agreement called that aimed to reduce CFC emissions?

• Geneva Convention

• Montreal Protocol

• Paris Agreement

• Kyoto Protocol

Which layer of the atmosphere do we live in?

• Troposphere

• Mesosphere

• Thermosphere

• Stratosphere

What is the main difference between weather and climate?

• Weather is short-term; climate is long-term

• Weather is constant; climate changes daily

• Weather is global; climate is local

• Weather is predictable; climate is random

What causes the Coriolis effect?

• Earth's rotation

• Sun's gravity

• Moon's orbit

• Ocean currents

Which atmospheric cell is located closest to the equator?

• Polar cell

• Ferrel cell

• Hadley cell

• Tropical cell

What is the El Niño Southern Oscillation (ENSO)?

• A type of ocean current

• A pattern of atmospheric pressure

• A type of wind pattern

• A climate phenomenon affecting global weather

During an El Niño event, what happens to the trade winds?

• They weaken

• They strengthen

• They reverse direction

• They remain unchanged

What is the primary factor that creates convection cells in the atmosphere?

• Earth's magnetic field

• Ocean tides

• Unequal heating of the Earth's surface

• Solar flares

Which atmospheric layer is closest to space?

• Troposphere

• Mesosphere

• Exosphere

• Stratosphere
