Alfred Wegener first proposed the theory of continental drift in 1912. He suggested that the continents were once joined together in a supercontinent called Pangaea, which later broke apart and drifted to their current positions. Wegener's theory was initially rejected by many scientists. However, the theory of plate tectonics later provided a mechanism - seafloor spreading - that explained how the continents could move over time. Today, the movement of continents via plate tectonics is well established in the scientific community.

3. What are drifting continents???
• Drifting continents are the separation of continents.
This occur by the crash of plate tectonics.

4. INTRODUCCION
• The first truly detailed and comprehensive theory of
continental drift was proposed in 1912 by Alfred
Wegener, a German meteorologist.

5. Life of Alfred Wegner
• Alfred Lothar Wegener was born on
November 1, 1880 in Berlin, Germany. During
his childhood Wegener's father ran an
orphanage. Wegener took an interest physical
and Earth sciences and studied at universities
in both Germany and Austria.

6. The theory of Alfred Wegener
• In the early 20th century the scientist Alfred
Wegener publised a book about landmasses
movement and he called that drifting continents.

7. The theory of Alfred Wegener
• At the beggining, other scientists did not
accept Wegener’s theory of continental drift.
The plates are always moving and interacting
in a process called plate tectonics.

9. Drifting Continents
• The continents are still moving today.
Underwater exploration has revealed seafloor
spreading. Seafloor spreading is the process of
new crust forming between two plates that
are moving apart. As the seafloor grows wider,
the continents on opposite sides of the ridges
move away from each other.

10. Drifting Continents
• If you could visit the planet in the future, you
would find a part of California separated from
North America, becoming an island in the
Pacific Ocean. It is even possible that another
super continent like pangaea may form
someday.

12. Movement of Drifting Continents
Continental drift is the movement of the Earth's
continents relative to each other, thus appearing to
"drift" across the ocean bed.

13. The pangea
• The hypothesis that the continents
had once formed a single landmass,
called Pangae.
• The hypothetical landmass that
existed when all continents were
joined, from about 300 to 200 million
years ago.

15. Continents
• A continent is one of several very large landmasses
on Earth. They are generally identified by convention
rather than any strict criteria, with up to seven
regions commonly regarded as continents.

16. Continental drift
• According to scientistics the world is broken into
pieces because the ocean floor is broken more and
more every year, and one year will be Ecuador a
continent in the future.

17. Why it produce?
• The reaction to Alfred Wegener's Continental Drift
Theory demonstrates that new ideas threaten the
establishment, regardless of the century.

18. Continental drift
• The movement, formation, or re-formation of
continents described by the theory of plate
tectonics.
• Geology the lateral movement of continents
resulting from the motion of crustal plates.

19. Ideas
• His ideas were largely ignored at the time they
were developed but today they are very well
accepted by the scientific community.
• Wegener also took an interest in meteorology
and paleoclimatology (the study of changes to
the Earth's climate throughout its history.)
