Extreme Living: The Sahara

In 1981, NASA geologist Dr. Farooq Al Baz used space technology to locate freshwater reserves beneath the Sahara Desert. By employing radar imaging, he discovered significant water deposits, which led to the creation of a green oasis in the desert. This discovery allowed for the drilling of wells, enabling agriculture and providing a sustainable water source for local communities. The freshwater reserves are expected to last for up to a century, transforming one of the most inhospitable places on Earth into a productive agricultural area.

What was Dr. Farooq Al Baz's initial challenge in photographing the Sahara?

• The landscape was too mountainous.

• There were too many clouds.

• The equipment was malfunctioning.

• The landscape was barren and featureless.

Who assisted Dr. El Baz in using radar imaging to explore the Sahara?

• Sally Ride

• Neil Armstrong

• Charles Alashi

• Buzz Aldrin

What did the radar imaging reveal beneath the Sahara's surface?

• Freshwater reserves

• Gold deposits

• Ancient ruins

• Oil reserves

What was the result of drilling wells in the Sahara after the discovery?

• The wells were dry.

• The wells collapsed.

• They found oil instead of water.

• The wells produced water, enabling agriculture.
