all of the above
What type of Boundary is this? What event will occur at this boundary?

Why did people not believe in Wegener's theory about continental drift?
There was a competing theory at the time that was more believable.
There was no data showing the continents ever moved.
The scientists did not know the force responsible for moving the continents.
The scientist presenting the data was unreliable.
The Himalayas are an example of what happens at a?
convergent boundary
divergent boundary
transform boundary
allegiant boundary
The earthquakes experienced in California are related to tectonic plates because these catastrophic events are the result of -
two tectonic plates sliding past each other.
tectonic plates melting as they slide into the mantle.
tectonic plates being weathered over time.
two tectonic plates pulling away from each other.
One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?
The ancient atmosphere in both places was identical.
The rates of weathering of rock are similar.
Fossil remains of the same land-dwelling animal.
Plants on both continents have similar flowers.
Even before modern observations provided evidence that supports the Theory of Plate Tectonics, people developed theories that the continents were once joined together. Using only maps, they observed that -
most of the larger land masses are in the Northern Hemisphere.
continents with the most moderate climates were located near the Equator.
the shapes of continents appeared to allow them to fit together.
the oceans have decreased in size throughout the history of Earth.
Which of the following features is likely to form where two tectonic plates push toward each other?
Ocean shoreline
Mountain range
Mid-ocean ridge
Rift valley
Which of the following crustal features would be the result of two continental tectonic plates moving away from each other?
Mountain range
Volcanoes on land
Rift valley
Mid-ocean ridge
Every 100,000 to 200,000 years, the magnetic poles of Earth reverse. Rocks that contain iron provide a record of both normal and reversed magnetic poles. The pattern of normal and reversed magnetic poles as recorded in the rock on either side of the Mid-Atlantic Ridge provide evidence supporting the Theory of Plate Tectonics because -
the composition of the rock changed every time the plates pushed against each other.
the symmetric pattern shows where plates are moving away from each other.
deposits of iron in the rock were only made when the plates stopped moving.
" the bands of rock showing normal and reversed poles are not all the same width."
