When a fossil of an animal is found on almost all continents, then it supports
the idea of a traveling animal
the idea of a connected original continent
the idea of a flying animal
Fossils can also give evidence for a Pangaea theory
True
False
What evidence of Wegener's Theory is shown in the remains of organisms that lived long time ago?
embryology
continental drift
seafloor spreading
fossils
One piece of evidence for Plate Tectonics is that--
some continents appear to fit together like a puzzle.
we have video footage of the plates actually moving.
all continents have formed from volcanic eruptions.
the continents are no longer moving.
Fossil records indicate that the continents were once connected. How do fossil records support this claim?
We have been able to transport the same types of fossils from one continent to another.
Fossils of the same organism that are chemically and physically similar have been found on continents that are now separated by oceans.
Some continents contain fossils of many different types of organisms.
The age of the Earth is measured in _______ of years.
millions
billions
This is a model of sea floor spreading at a divergent boundary called a_________________________________
Divergent boundary
Transform boundary
Mid Ocean Ridge
Oceanic Crust
The formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side is called
Subduction
Seafloor Spreading
Divergent boundary
Convergent boundary
Wegener’s theory was rejected by scientists because he could not explain what ____________ pushes or pulls continents.
continent
magma
force
drift
Wegener’s theory that all continents had once been joined together in a single landmass and have drifted apart since.
Seafloor Spreading
Continental Drift
Subduction
Pangaea
The deepest parts of the ocean; long, narrow ditches
Trenches
Divergent Boundary
Lithosphere
Subduction
Tectonic Plates
The magnetic pattern of ocean-floor rocks on one side of an ocean ridge is_____________.
a mirror image of that on the other side
younger than other side
much different pattern
at right angles to the ridge
The OLDEST seafloor is located
closest to the mid-ocean ridge.
farthest from the mid-ocean ridge.
east of Hawaii
west of California
Scientists use ______ to map the ocean floor
radar
pulsar
lidar
sonar
How is it possible for new crust to be formed without increasing the surface area of the Earth?
Crust is recycled in subduction zones at the same time it is created at mid-ocean ridges
New crust is underwater where it sinks
New crust breaks more easily than old crust
The oldest crust just breaks apart as the plates move
