this power point will help you to understand continental drift and how it happened.also we hope you enjoy this and find it useful.the whole team put allot of effort into this and think you will enjoy!!!
2. Continental drift
Continental drift is where the continents spilt from the mega continent
(Pangaea). The continents of America and Africa used to be joined
together and fitted like a giant jigsaw puzzle!
3. Evidence for continental drift.
• The evidence of the continental drift is the
mechanism for plate tectonics. South America
and Africa fit together. Also fossils on the
other side of the world match that of the
fossils found on the other side of the planet!
How does that happen the answer
CONTINENTAL DRIFT!!!
4. How did the plates move?
• The plates move because they where on the
water surface and the currents of molten rock
and are on top of a mantle that produces
radioactive forces jostling causing the plates to
uproot and move. Also eight major plates on
the surface of the world there are also
bunches of mirror plates the plates are on the
skin of the planet. They are constantly moving
around the planet (by a couple of centimetres
a year).
5. What is the structure of the world
• the earth is a layered structure made up of the
core the mantle the crust and tectonic plates
these move slowly over the mantle that
pushes up through the rock.
