Proposed by Alfred Wegener, that the continents were once joined together and have since drifted apart
theory of plate tectonics
tectonic plates
plate boundary
theory of continental drift
Oceanic Trenches are formed by either _______ or _______ plate boundaries
Convergent Oceanic / Continental
Convergent Continental / Continental
Convergent Oceanic / Oceanic
Divergent
In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?
The strong ocean currents are undermining both areas causing earthquakes.
Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.
Both areas are subjected to strong ocean wind and waves that causes earthquakes.
Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.
Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that
the oceanic crust is melting.
the denser ceanic crust is subducting under the less dense oceanic crust
volcanic islands are forming.
the tectonic plates are moving away from each other.
The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future
droughts
hurricanes
earthquakes
tornadoes
Earthquake epicenters (center of where the earthquakes started) were mapped for a 35 year period in the diagram above. The black dots indicate these epicenters. The black dots appear along what feature on Earth?
hot spots
plate boundaries
rift zones
sea floor spreading
Which of the following were peices of evidence used by Alfred Wegener to support his hypothesis of Continental Drift? (choose ALL that apply)
fit of the continents
matching rocks and mountains across continents
matching fossils across continents
evidence of glaciers in places now too warm
magnetic striping on the seafloor showing seafloor spreading
What causes the uneven distribution of earth's resources?
plate tectonics, rock cycle, and erosion
natural disasters
ONLY plate tectonics
asteroids
According to data on the map, along what boundary is copper usually formed and why?
divergent, because of the sea floor spreading
transform, because of the earthquakes
convergent, because of subduction
diffusion, because of convection
