Ocean Currents and Weather Patterns

The video explores how weather patterns and global climate are influenced by various factors, including the interaction between the ocean and atmosphere. It covers severe weather phenomena like thunderstorms and tornadoes, explaining their formation. The video also discusses hurricanes, cyclones, and the impact of ocean temperatures. It delves into the El Niño and La Niña phenomena, highlighting their effects on global weather. Finally, it addresses global climate change, emphasizing the role of human activities in enhancing the greenhouse effect and its potential consequences.

How do the ocean and atmosphere interact to influence weather patterns?

• They have no impact on each other.

• The atmosphere solely dictates ocean currents.

• They operate as closed systems independently.

• The ocean currents affect wind patterns, and vice versa.

What typically causes severe thunderstorms?

• Cold air colliding with cold air.

• Warm air colliding with warm air.

• Cold air sinking below warm air.

• Warm air rising over cold air.

What is a necessary condition for a tornado to form?

• A funnel of air remaining in the sky.

• A funnel of air touching down on land.

• Warm air sinking rapidly.

• Cold air rising rapidly.

What is the primary factor that influences the strength of a hurricane?

• The amount of rainfall in Africa.

• The temperature of ocean water.

• The speed of trade winds.

• The presence of dust in the atmosphere.

What is the difference between a hurricane and a cyclone?

• Hurricanes occur over the Pacific Ocean, cyclones over the Atlantic.

• Hurricanes and cyclones are the same but named differently based on location.

• Cyclones are stronger than hurricanes.

• Hurricanes are stronger than cyclones.

What happens to ocean currents during an El Niño event?

• They reverse direction completely.

• They slow down or stop, affecting nutrient upwelling.

• They remain unchanged.

• They become stronger and faster.

How does El Niño affect global weather patterns?

• It only affects the Pacific Ocean region.

• It causes uniform weather conditions worldwide.

• It leads to unpredictable and varied weather changes.

• It has no significant impact on global weather.

What is a potential consequence of global climate change on ocean currents?

• No impact on ocean currents.

• Disruption of the global ocean conveyor.

• Complete cessation of ocean currents.

• Strengthening of the global ocean conveyor.

What is the primary greenhouse gas contributing to global warming?

• Oxygen

• Helium

• Nitrogen

• Carbon Dioxide

What could happen if the global ocean conveyor shuts down?

• The ocean would hold more CO2.

• Weather patterns would become more predictable.

• Global temperatures would stabilize.

• Europe could experience an Ice Age.
