Science Unit 3 cards Flashcards
Recall the name of the giant supercontinent in the illustration below:
Pangea
Match the correct plate boundary to the illustrations below:
A. Convergent
B. Divergent
C. Transform
The maps below show the positions of two continents at two different times. The movement of the continents may be best explained by:
Seafloor spreading
Predict what natural event will occur at the boundary shown below
Earthquakes
Summarize how each geologic feature was formed by the movement of the Earth’s tectonic plates:
Mountains: When two tectonic plates collide
Volcanoes: When tectonic plates move away from one another
Oceanic crust: When tectonic plates tear away from each other
Oceanic ridges: When new ocean floor is created and tectonic plates spread apart
Explain three pieces of evidence that lead us to believe many continents were once connected:
One piece is similar fossils found on different continents
The continents fit together like a jigsaw puzzle
Similar rock types were found on similar continents
Explain what happens to the tectonic plates located at the Ring of Fire and what natural events occur there:
The tectonic plates there move side by side, or move away from one another causing volcanoes and earthquakes to be common natural disasters here
