Plate tectonics involves the movement of tectonic plates which form the continents and oceans. This movement is caused by convection currents in the molten rock beneath the plates. As the plates move, they push against each other causing mountains to form. The Earth's core, made of iron and nickel, generates the planet's magnetic field as it rotates, similar to a dynamo. This magnetic field protects the Earth from solar radiation. While plate tectonics and the inner workings of the planet remain mysterious, it continues to shape our world and protect it every day.

PLATE TECTONICS

2. Plate tectonics is the cause of continental drift and mountain building.
He found the same old species on different continents.
This was discovered in 1929 by Alfred Wegener.
Then, He proposed the continental drift
And the existence of Pangea

4. BUT... WHY IS ALL THIS HAPPENING?
• These plates form the continents, mountains and oceans. And
they are moved by currents of molten rock, which are under the
plates.
*These currents are called convection currents. And they born in the
planet core.

6. • While the plates move, push stones and mountains are forming.

7. THE MAGNETIC FIELD
• Geodynamics also protects us from solar radiation.
• The core made of iron and nickel, rotates, and generates the
magnetic field of the earth. Like a Dynamo.
• The radiation that entering in the earth, is reflected as aurora borealis

9. • The Sg3 well was closed in 1989, when workers reached 12km, they punctured a
huge underground cave which had 1000 degrees Celsius.
• The heat made it excavator 5km ground burst and buried workers.
• The well remains closed today

10. • Very little is known about the geodynamics.
The interior of the planet remains an enigma to humans. Although
it protects us every day.
