NASA | Earth Science Week: Keeping Up With Carbon

The video explains the carbon cycle, highlighting carbon's presence in Earth's ecosystems, including land and oceans. It discusses the ocean's role as a carbon sink and its impact on climate regulation. Human activities have increased atmospheric carbon dioxide, affecting climate and marine life. Future challenges include warming oceans and reduced carbon storage. NASA satellites help monitor these changes, providing insights into Earth's climate health.

What is the significance of the carbon cycle in understanding Earth's climate?

• It helps in predicting weather patterns.

• It controls the Earth's gravitational pull.

• It is crucial for understanding climate change.

• It determines the Earth's magnetic field.

Why is the ocean referred to as a 'carbon sink'?

• Because it produces carbon naturally.

• Because it absorbs carbon from the atmosphere.

• Because it releases carbon into the atmosphere.

• Because it has no effect on carbon levels.

How do phytoplankton contribute to the carbon cycle?

• They release carbon dioxide into the atmosphere.

• They use carbon dioxide for photosynthesis.

• They prevent carbon from entering the ocean.

• They consume carbon from the ocean floor.

What has been the impact of human activities on atmospheric carbon dioxide levels?

• They have increased by more than 30%.

• They have decreased by 30%.

• They have no impact.

• They have remained constant.

How does increased carbon dioxide in the atmosphere affect marine life?

• It makes the ocean less acidic.

• It makes the ocean more acidic, threatening some organisms.

• It increases the ocean's temperature.

• It has no effect on marine life.

What role do NASA satellites play in understanding the carbon cycle?

• They track the Earth's magnetic field.

• They measure the Earth's gravitational pull.

• They offer a big picture view of Earth's climate and ecology.

• They provide a detailed view of individual plants.

What happens to the ocean's ability to store carbon as the planet warms?

• It becomes more effective at storing carbon.

• It remains unchanged.

• It becomes less effective at storing carbon.

• It starts producing carbon.
