It may be roughly possible to fit the shapes
of the continents together like the pieces of
a jigsaw puzzle
Similar fossils are found on different
continents, e.g. fossils of an ancient horse
called the Hipparion have been found in
both France and Florida
Rock formations on land masses are the
same on different sides of the Atlantic
ocean
It has been possible to do more geological
surveys on the Earth than other rocky
planets in the solar system
Land bridges could have existed between
continents
The magnetic alignment in rocks of the
same age are found on different continents
Wegner, the person who proposed the idea
of continental drift, was a meteorologist
(studied the weather), not a geologist
Magnetic studies of the ocean floor have
shown that there is spreading of the
Atlantic ocean sea bed
Some volcanoes exist at points where the
Earth’s crust is thin
Geological surveys have shown that the
canyon in the mid-Atlantic ridge (a rock
formation in the Atlantic ocean) continues
to get wider
Other events in the history of the Earth
could be used to explain why animals have
become extinct, e.g. meteorites, volcanoes,
etc.
Denver in America has risen by thousands
of metres since the age of the dinosaurs and
it is not known to be near the edge of a
‘plate’
Denver has moved considerably in its
history, yet the rock formations show no
sign of distress due to this movement
Mountain ranges are not evenly distributed
across the surface of the earth
Some volcanoes exist at points where the
Earth’s plates move apart

Wegner calculated that Greenland was
moving at a rate of 1.6 km per year. This
has been proven to be much too fast.
Subduction is a process where rock
material gets pushed under the Earth’s crust
and recycled
Earthquakes can be explained by tectonic
plates rubbing together
Mountain ranges on the Earth are not all
the same age
Earthquakes may be caused by changes in
air pressure
The plates that the continents sit on are
often bigger then the land mass that can be
seen
Earthquakes may be caused by explosions
in the core of the Earth
Earthquakes may be caused by changes in
the tide patterns of the Earth

Einstein supported a book that said that
plate tectonics was not possible
Venus is a rocky planet similar to Earth in
terms of its composition, and has no molten
core
The earth was once a molten ball. In the
process of cooling the surface cracked and
folded up on itself. This is called the
contraction theory.
GPS has shown that Europe and North
America are moving apart at the same rate
as a fingernail grows
The age of the sea bed has never been
found to be more than 175 million years
old; other rock formations are billions of
years old
If the amount of sediment that flows into
the sea from rivers remained on the sea
bed, the ocean floor would now be above
sea level
Earth is the only known rocky planet where The core of the Earth has remained molten
plate tectonics have been suggested
