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.
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
The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?
The region is bound by many oceanic trenches.
North America seems to be colliding with Asia at the north of the ring.
The region is dotted by volcanoes and experiences major earthquakes and tsunamis.
The landmasses look like they would fit together like the pieces of a jigsaw puzzle.
The Marianas Trench, where the Pacific Plate descends under the leading edge of the Eurasian Plate, is the deepest sea floor in the world. These ocean trenches form when two oceanic plates collide
and the older, less dense of the two plates rides over the edge of the older plate.
when convection currents in the mantle force the older plate downward.
and the younger, denser of the two plates, rides over the edge of the older plate.
and the plates are approximately the same age and density.
This theory states that Earth's crust is divided into large pieces that float on the mantle.
The Theory of Crust Motion
The Theory of Plate Tectonics
The Theory of Past Tectonics
The Theory of Plate Technicalities
Iceland [in yellow on the map] is located in the middle of the Atlantic Ocean. Geologists consider it a fascinating place because of all the volcanoes, geysers, and hot springs found there! It is an excellent location for geothermal energy use. Use the tectonic map to explain why it is such an active place for geology.
Iceland sits above a convergent boundary.
Iceland sits above a divergent boundary.
Iceland sits above a transform boundary.
Iceland is at a subduction zone

Which type of evidence was NOT used by Alfred Wegener to support his continental drift hypothesis?
Similar mountain ranges found on the eastern side of South America and the western side of Africa.
Identical fossils found on different continents.
Erosion and Weather appears on Mountain Ranges across the world.
Glacial erosion found in Australia India,and Africa.
Coal is an example of climate change evidence because...
it is found in tropical areas today so it used to be near the equator
it is found in swampy areas today so the area used to be near the poles
it is found in cold areas today so it used to be closer to the equator
coal is not an example of climate change

How does evidence of glaciation in Africa support the Theory of Continental Drift?
It shows that the continents must have been in a different location (Polar Wandering).
It doesn't.
I shows that it was colder at the equator in the past.
It shows that it was warmer at the equator in the past.
What are the remains of organism noticed by Wegener that are found the same in two continents?
Leaves and flowers
Ice and mountains

Dinosaurs and reptiles
Which of the following best describes Wegener's continental drift ideas?
Hypothesis: There was data to support the idea but more information was needed to build it into a scientific theory.
Theory: It was an early idea of Wegener's but it didn't yet have any evidence to support it.
Theory: It was a well supported idea that explained many things. No additional information was needed (it just needed time for people to accept it).
Hypothesis: It was an educated guess that Wegener made based on maps, but he hadn't yet collected experimental data.
