Ciclos climáticos

The video explores how ice cores from Greenland provide insights into Earth's climate history. By analyzing layers of ice, scientists can determine past temperatures and identify events like volcanic eruptions and industrial activities. The data reveals that while climate changes can occur over thousands of years, there are also rapid shifts within decades. This understanding helps reconstruct the climate of the past 50,000 years, showing long ice ages and sudden warming periods.

What do the different layers in ice cores represent?

• Different time periods

• Different temperatures

• Different locations

• Different types of ice

What can be found in the ice cores that indicate past volcanic activity?

• Traces of sulfur

• Salt deposits

• Remains of ash and acid

• Carbon dioxide levels

How do scientists determine the temperature of past eras using ice cores?

• By measuring the thickness of ice layers

• By counting the number of layers

• By analyzing the chemical composition of water

• By observing the color of the ice

What does a larger amount of a specific type of hydrogen in ice indicate?

• Higher altitudes

• Lower altitudes

• Warmer temperatures

• Colder temperatures

What surprising climate change can occur within just 10 years according to the ice cores?

• A change in atmospheric pressure

• Several degrees of temperature change

• A shift in ocean currents

• A complete ice age
