Cyclic Fluctuations and Climate Change

What are El Niño and La Niña and how do they affect global climate patterns?

• El Niño and La Niña are fictional characters from a children's book, they have no impact on global climate

• El Niño and La Niña are climate patterns resulting from variations in ocean temperatures in the Equatorial Pacific, affecting global weather and climate.

• El Niño and La Niña are types of tropical fruits that grow in the Equatorial Pacific, they have no effect on global climate

• El Niño and La Niña are two new dance moves popular in South America, they have no influence on global climate

Explain the formation and characteristics of tornadoes.

• Tornadoes form from ocean waves and are characterized by calm, sunny weather.

• Tornadoes form from volcanic eruptions and are characterized by heavy snowfall.

• Tornadoes form from powerful thunderstorms and are characterized by rotating, funnel-shaped clouds with high wind speeds.

• Tornadoes form from gentle rain showers and are characterized by still, clear skies.

Discuss the factors that contribute to the formation and intensity of hurricanes.

• Warm ocean water, high wind shear, and atmospheric stability

• Low ocean water, high wind shear, and atmospheric instability

• Warm ocean water, low wind shear, and atmospheric instability

• Cold ocean water, high wind shear, and atmospheric stability

What are tsunamis and how do they differ from regular ocean waves?

• Tsunamis are man-made waves and differ from regular ocean waves in terms of their purpose and the materials used to create them.

• Tsunamis are small ripples in the ocean caused by the gravitational pull of the moon and differ from regular ocean waves in terms of their frequency and direction.

• Tsunamis are large ocean waves caused by underwater earthquakes or volcanic eruptions. They differ from regular ocean waves in terms of their size, speed, and the way they are generated.

• Tsunamis are caused by strong winds and differ from regular ocean waves in terms of their color and temperature.

Explain the concept of continental drift and its impact on climate change.

• Continental drift is caused by climate change

• Continental drift has no impact on climate change

• Continental drift has impacted climate change by altering the distribution of landmasses and oceans, which has in turn affected ocean currents, wind patterns, and the overall climate of different regions.

• Continental drift only affects the movement of tectonic plates

How do El Niño and La Niña events influence weather patterns in different parts of the world?

• El Niño events lead to drier conditions in the eastern Pacific

• La Niña events lead to warmer and wetter conditions in the eastern Pacific

• El Niño events can lead to warmer and wetter conditions in the eastern Pacific and drier conditions in the western Pacific, while La Niña events can lead to the opposite pattern.

• El Niño events have no impact on weather patterns

What are the warning signs of an approaching tornado and how can people stay safe during a tornado?

• The warning signs of an approaching tornado include heavy rain and a calm, quiet atmosphere

• To stay safe during a tornado, people should go outside and try to outrun the tornado

• The warning signs of an approaching tornado include dark, greenish sky, large hail, and a loud roar similar to a freight train. To stay safe during a tornado, people should seek shelter in a sturdy building, preferably in a basement or an interior room on the lowest floor, and protect themselves from flying debris.

• The warning signs of an approaching tornado include clear blue skies and a gentle breeze

Discuss the role of ocean temperature in the development of hurricanes.

• Cold ocean water provides the energy needed for the formation and intensification of hurricanes.

• Ocean temperature has no impact on the development of hurricanes.

• Warm ocean water provides the energy needed for the formation and intensification of hurricanes.

• Hurricanes are caused by air pressure, not ocean temperature.

What are the primary causes of tsunamis and how can coastal communities prepare for them?

• Tsunamis are caused by pollution and global warming. Coastal communities can prepare by reducing carbon emissions and planting more trees.

• Underwater earthquakes, volcanic eruptions, and landslides. Coastal communities can prepare by creating early warning systems, building tsunami-resistant structures, and educating residents about evacuation procedures.

• Tsunamis are caused by the gravitational pull of the moon and sun. Coastal communities can prepare by conducting regular tsunami drills.

• Tsunamis are caused by heavy rainfall and strong winds. Coastal communities can prepare by stocking up on food and water supplies.

Explain the evidence for continental drift and its connection to climate change.

• Continental drift is caused by the movement of tectonic plates

• Continental drift is supported by evidence such as the fit of the continents, matching geological formations, and the distribution of fossils. The movement of continents can affect ocean currents and the distribution of landmasses, which in turn can impact global climate patterns.

• The evidence for continental drift is based on the movement of the moon

• Climate change has no connection to continental drift
