PHILOSOPHICAL INQUIRY:THE CONCEPT OF SUNSTAINABILITY

EARTH – ABSTRACT

2

The planet Earth is the fifth largest in the solar system and the third closest to the Sun. The

Earth has the highest density of any planet. Its diameter is more than 12,700 km and it has

existed for about 4.6 billion years. It is the home of all known living organisms.

The mass of the Earth is composed mainly of iron (32,1 %), oxygen (30,1 %), silicon (15,1 %),

magnesium (13,9 %), sulfur (2,9 %), nickel (1,8 %), calcium (1,5 %) and aluminum (1,4 %).

The remaining 1,2% are traces of other elements.

According to seismic measurements the structure of the Earth consists of mainly three

layers: the Earth’s core, the mantle and the crust. These layers are separated by seismic

discontinuity zones of each other. The Earth's crust and the uppermost part of the upper

mantle together form the so-called lithosphere. The lithosphere ranges between 50 and 100

km in thickness and is divided in so-called tectonic plates.

As the Sun and the other planets the Earth originated about 4.6 billion years ago from the

compression of the solar nebula. It is now generally accepted that during the first 100 million

years the Earth was exposed to an intense bombardment by asteroids. In contrast to the moon,

on Earth almost all impact craters have been removed by geological processes.

Because of the conversion of the kinetic energy of the asteroids on impact into heat during the

heavy bombardment and by the heat production of the radioactive decay the young Earth was

heated until it was mostly melted. As a result, there was a gravitational differentiation of the

Earth into a core and mantle. The heaviest elements, especially iron, sank into the center of the

planet, whereby heat was produced. Lighter elements, especially oxygen, silicon and aluminum,

rose up and formed silicate minerals, which mainly make up the rocks of the Earth's crust.

Discussion plan:Reality

What is reality? What is the difference between reality and truth?

Is there existence or reality beyond our

subjective perception?

How real is reality?

What is the difference between realness and reality?

What is the difference between

real and reality? What is the

difference between reality and illusion?

How important is reality for humans?

Schwalbenwitz

Wahrlich, wahrlich, ich sage euch,Himmel und Erde sind sich gleich.

Spricht der Himmel: Werde!Da grünt und blüht die Erde!

Spricht die Erde: Sterbe!Da wird der Himmel ein lachender Erbe.

Sterne sah ich blinken und sinken,Den Mond in der Sonne ertrinken,

Die Sonne stieg in die Meere,Ohne daß sich ein Fünklein verlöre.

Feuer und Wasser hassen sich,Erde und Wasser umfassen sich,Luft und Feuer entzünden sich,Erde und Feuer ersticken sich,Erde und Luft umkühlen sich,

Luft und Wasser umspielen sich,Aber alles ist Liebe, Liebe, Liebe,

Und wenn sich alles empörte, verzehrte, verschlänge,

Daß gar nichts bliebe, bliebe doch LiebeDie Hülle, die Fülle, die Menge

Discussion plan:Beginning and end

What was at the beginning of the

universe?

Can one imagine the beginning of all

beginnings?Has the universe

been here forever or did it

have a beginning?

Was the Big Bang the beginning of the

universe?

How can one imagine a spatial end

of the universe?What will

follow after the end of the universe?

What happened before earth has

evolved?
