The older seafloor sinks, the weight of the uplifted ridge pushes the oceanic crust toward the trench at the subduction zone. This process is called _____.
ridge push
slab pull
subduction
earthquake
Where does convection current occurs?
crust
mantle
core
inner core
If you are a cartographer, what would give you an idea that the continents were once joined?
ocean depth
position of the South Pole
shape of the continents
size of the Atlantic Ocean
Which of the following can you infer from the continuous movement of the lithospheric plates over the asthenosphere?
all the continents will cease to exist
all the volcanoes in the Philippines will become inactive
the continents will not be located in the same place as they are now
the islands of the Philippines will become scattered all over the world

the force of the atmosphere

it remained as supercontinent
it would have become as it is today
it would have slowly disappeared in the ocean

subduction
This German scientist first proposed continental drift theory
Harry Hess
Alfred Wegener
Archimedes
Thomas Warner
Wegener noticed that the Appalachian Mountains and Caledonian Mountains line up and are made of the same rock types. This was a type of ....
Fossil Evidence
Rock Formation Evidence
Climate Evidence
Objective Evidence
Wegener found fossils of land reptiles on two different continents. This was important because
Land reptiles are often found all over the world, showing that they can survive in most climates
Land reptiles cannot swim, so the continents must have been connected for them to get across
Land reptiles are never moved around the Earth by humans, so they must have travels to these continents by themselves
Land reptiles fossilized much better than other animal species
Wegener found fossils of ancient ferns on Antarctica, this shows
That some ferns can survive temperatures well below freezing
That humans put ferns on Antarctica millions of years ago
That Antarctica drifted from a warmer climate where plants could grow
That fossils can be formed in cold climates
