Wegener confirmed that flora and fauna fossils matched the same types of fossils
across different continents. This supported his claim that the continents were once joined together.
Two key examples that he studied were Mesosaurus fossils (a freshwater reptile) and Glossopteris
fossils (fern-like gymnosperm plant). Which of the following statements about Glossopteris fossils provides the
best evidence to support Wegener’s Continental Drift theory?
a. | Glossopteridales thrived in the Southern Hemisphere during the Permian Period, but
they went extinct during the Permian-Triassic mass extinction event. | b. | These organisms were
initially thought to be ferns, but modern analysis suggests that they were deciduous gymnosperm
plants. | c. | Glossopteris fossils are found in India, South America, Australia, Africa, and
Antarctica. This distribution is best explained by tectonic plate movement.

A large semi-circular area in the Pacific ocean that includes numerous volcanoes
and frequently experiences earthquakes is called the ring of fire. How does volcanic activity and
earthquakes along the ring of fire support tectonic plate theory?
a. | Earthquakes are powerful seismic waves that propagate through lithospheric
rock. | b. | Heat rising from the core via convection can melt rock. As pressure builds up this
magma can erupt on the surface to form volcanoes. | c. | Volcanoes and earthquake often occur along the
boundary of the Pacific plate as it collides with other tectonic
plates. |

The Himalayan mountains in Asia are located along India’s northern
border. What cause and
effect connection below best explains how this mountain range was formed?
a. | Cause: An elongated magma plume ruptured the lithosphere in the
Mid-Atlantic. Effect: Seafloor spreading occurred which formed the Himalayan mountain
range. | b. | Cause: The Indian tectonic plate collided with the Eurasian
plate. Effect: Lithosphereic rock along the plate boundaries was crumpled and
lifted. | c. | Cause: Convection currents melted Eurasia’s lithosphere over a large
area. Effect: The Eurasian tectonic plate slipped southwards impacting the Indian
plate. |

To support his Continental Drift theory, Alfred Wegener studied fossils found on
different continents. He discovered that Mesosaurus fossils (a freshwater reptile from the Permian
period) provided good evidence that supported his ideas concerning tectonic plate movement. . How do Mesosaurus fossils support
the Continental Drift/Plate Tectonics theory?
a. | Fossils of Mesosaurs are only located along active geological fault lines at
convergent boundaries in subduction zones. This is solid evidence for plate
tectonics. | b. | Mesosaur fossils are found in South America and Africa. As a freshwater organism, it
is highly unlikely that these reptiles could swim across the vast Atlantic ocean. | c. | Mesosaurs were
slender carnivorous reptiles that thrived in the Permian period, and they are related to modern
turtles and tortoises. |

How did scientists discover that rocks farther away from the Mid-Atlantic
Ridge were older than those near it?
a. | by studying rocks found in the Appalachian mountains and Himalayan mountains.
| b. | by determining the age of rock samples obtained by drilling on the sea
floor | c. | by measuring how fast the Indian plate was colliding with the Eurasian plate.

According to Wegener’s ideas about continental drift...,
a. | ...the continents were once joined together in a single landmass. | b. | ...the Earth’s
diameter is gradually increasing as new crust is formed. | c. | ...the continents
are slowly melting due to heat from Earth’s core. |

Imagine that you are a geologist in 1913 working with Alfred Wegener. You are
attempting to find evidence to support his Continental Drift theory. Together you examine the
Appalachian Mountains in North America, the Scottish Highlands in Great Britain, and the Caledonian
Mountains in Scandinavia (see map below). You find that these mountain ranges have very similar
features. Multi-Select
QuestionAs Wegener’s partner you are asked to construct an explanation about his
Continental Drift theory. Which of the following points about the previously mentioned mountain
ranges would best support Wegener’s claims that the continents were once joined together as a
single huge landmass. (Select 3 of the 5 choices).
