franceinfo junior. "How do scientists know what’s under the Earth?"
Cairo: Mai Kamal El-Din
Today’s franceinfo junior show takes a trip to the center of the Earth. The Louvre-Lens museum is currently offering an exhibition entitled “Underworlds. 20,000 places under the Earth”. Films, books, sculptures… this exhibition offers 200 works of art to help us discover what lies beneath our feet.
Arnaud Lemaistre, geologist, head of the Earth Sciences department at the Palais de la Découverte, responds to schoolchildren from the French Lycée in San Diego in the United States.
The first question goes to Emma: “How do scientists know what’s under the Earth?” It is necessary to “relatively developed techniques since we cannot have direct access to what is very deep”, explains the guest.
“How do we explore the center of the Earth?” Mazen asks immediately. “Why is it hot at the center of the Earth?” completes Miles on the microphone.
“What is the rarest mineral beneath the Earth?” asks Raoul to close this show.
On this page, listen again to this franceinfo junior program in full with the children’s questions and the answers from a specialist.
