NASA | Satellite Tracks Saharan Dust to Amazon in 3-D

The video discusses the transport of Saharan dust to the Amazon rainforest, highlighting its significance in providing essential nutrients like phosphorus to the Amazon's ecosystem. It explains the role of NASA's Calypso satellite in studying dust and cloud structures and how annual variations in dust transport are influenced by rainfall in the Sahel region. The video emphasizes the importance of satellite data in understanding and modeling dust transport for future climate scenarios.

What is the approximate size of the Sahara Desert compared to?

• The continent of Africa

• The continental United States

• The Amazon Rainforest

• The Arctic Circle

What is the primary purpose of NASA's Calypso satellite?

• To track animal migrations

• To study the vertical structure of clouds and particles

• To monitor volcanic eruptions

• To measure ocean temperatures

How much dust, on average, is transported from Africa to the Amazon Basin each year?

• 182 million tonnes

• 100 million tonnes

• 50 million tonnes

• 27 million tonnes

What nutrient does Saharan dust provide to the Amazon Basin?

• Calcium

• Nitrogen

• Phosphorus

• Potassium

How does rainfall in the Sahel region affect dust transport to the Amazon?

• Rainfall has no effect on dust transport

• More rainfall decreases dust transport

• Less rainfall decreases dust transport

• More rainfall increases dust transport
