Question
Describe how plant fossils found at Svalbard in Norway gave evidence of drifting continents. (1 point)
• They were plants that became extinct millions of years earlier.
• They were found in glacial deposits.
. • They were warm climate plants that would not grow in a cold polar area.
• They were found only in that one location.
Which of the following describes evidence the Wegener used to support the theories of continental drift and plate tectonics.
Select TWO correct pieces of evidence.
(1 point)
Fossils of warm-climate plants were found in what are now polar areas, supporting the idea that the landmasses were once in different places on Earth's
口
surface.
• Wegener concluded these continents were once joined, due to the magnetic polarity pushing the continents apart.
• Wegener found fossils that were polar animals along the equator.
• Mesosaurus fossils were found in parts of South America and Africa separated today by an ocean.
Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one scientist proposed the idea of what? (1,
• undiscovered tectonic plate boundaries
hotspots
continental drift
pangea existence
How were the Himalayas formed? (1 point)
• due to an increase in volcanic activity
• when two plates collided with each other
• when a mid-ocean ridge split apart
• due to a sudden shift along a transform boundary
Which information is needed to construct a geomagnetic time scale?
Select the TWO correct answers.
(1 point)
• the length of the mid-ocean ridge
• the age of rocks along the surface of Earth
• the magnetic direction of rocks along the surface of Earth
• the average speed of tectonic plates on Earth

Select the THREE correct answers
(1 point)

Which statement describes a volcano that is classified as dormat? (1 point)

• It has never erupted.
• It is not expected to ever erupt again.
• It is expected to erupt soon.
Identify the type of plate boundary that created the volcanoes of Iceland. (1 point)
• a divergent boundary on land
• a convergent boundary on land
• a transverse boundary on land
• a divergent boundary in the ocean
What main process do all volcanoes have in common, regardless of the specific ways they form? (1 point)
• plate subduction
• plate divergence
• rising magma
• hotspots
Paleomagnetic evidence supports the theory of continental drift because the magnetic direction of a new layer of magma match the c
Earth's magnetic field while older layers are skewed. (1 point)
• True
false
Geologists found fossils of similar marsupials from the same time period across South America, Africa, Antartica, India, and Australia.
What theory is supported by this discovery?
(1 point)
• Early marsupials were strong swimmers.
• A vast land bridge once connected those continents.
• These processes happening today are the same processes that have occurred in the past.
• Those continents were once a part of one supercontinent.
At which type of plate boundary would a string of small volcanic islands most likely form. (1 point)
• transverse boundary
• convergent ocean-ocean boundary
• divergent ocean-ocean boundary
• convergent ocean-land boundary
What will happen where two continental plates collide at a convergent boundary? (1 point)
• The plated push up, forming a mountain range.
• One plate is subducted beneath the other
• The direction shifts and it becomes a transform boundary.
• A volcanic island arc is formed.
