The Earth.
It's a beautiful planet that
has land, oceans, and sky.
It also has many natural wonders
and many living creatures.
We human beings have built huge cities
and spread them across the globe.
But our living world is confined
to only the surface of the Earth.

Hi, my name is Kei Hirose, a
director of ELSI, Earth-Life Science
Institute of Tokyo.
We are walking every day on the Earth
with a consciousness of its existence.
Have you ever imagined
what is deep underground?
This picture what drawn in 1855.
Japanese people in that era believed a
giant catfish lived under the ground,
and when it runs wild,
an earthquakes occurs.
How ridiculous was that explanation,
given what we know today?
Don't you think so?
But no one has ever seen
the inside of the Earth.
In this course, Deep
Earth Science, we will
explore the interior of our planet.
Please join this course, and let's
imagine what's inside the Earth
together.
