Chapter 2 Plate Techtonics
That they Grand Canyon used to be below sea level under the ocean.
What do the fossils at the top of the Grand Canyon tell us about its history?
They create large mountians
What happens when two continents collide and one doesn't dive underneath the other?
The oceanic plate dives down underneath the continental plate.
What is true about a subduction zone?
Granite because it was less dense and buoyant.
What type of rock created the first continents, and why did it not sink down into the mantle?
Central region of tectonic plates
Where are earthquakes usually the LEAST common?
Ocean tides.
Which is NOT evidence for Wegener's theory of continental drift?
A chocolate covered cherry, it is solid at the core surrounded by a liquid layer and semi-solid layer, then covered in a thin solid coating.
Which of the following best describes the internal structure of the earth?
The mantle is mostly liquid
Which of the following is FALSE about the mantle?
Hurricanes.
Which of the following is NOT associated with convergent plate boundaries?
It is a subduction zone.
Which of the following is NOT true about the Mid-Atlantic Ridge?
inner core, outer core, mantle, crust
Which of the following is the correct order of the layers of the Earth from inside to outside:
It is located at a divergent boundary where the tectonic plates move apart.
Which of the following statements is TRUE about a mid-ocean ridge?
Which tectonic plate boundary is associated with the following features: strong to major earthquakes; NO volcanoes, no mountain chain is formed? (The San Andreas fault in California is a geographic example.)
transform plate boundary
Evidence for anthropogenic global warming.
All of the following were evidence for Alfred Wegner's theory of continental drift EXCEPT:
Made it very extreme, because it was so large and much was far from the oceans.
How did the supercontinent Pangea influence climate and weather and why does this happen?
Most earthquakes and volcanoes occur on or near plate boundaries.
How does knowing the location of plate boundaries help us prepare for natural disasters?
earthquake distribution
If you wanted to draw the boundaries of tectonic plates on a world map, which of the following maps would give you the most complete information?
It was bombarded by asteroids.
In early earth history, why was it difficult to retain a crust on the surface?
In both there is warm rising material and cooler sinking material
In what ways is movement of magma in the mantle similar to a lava lamp?
Continent-continent convergence
The Alps in Switzerland are associated with which of the following tectonic plate boundaries?
Continent-continent convergent boundary.
The Himalayas are associated with which of the following plate boundaries?
Transform Boundary
The San Andreas Fault is an example of which kind of tectonic plate boundary?
heat from the Earth's core.
The energy for Plate Tectonics comes from
nearest to the mid-ocean ridges
The youngest seafloor rocks are found:
