Eighth graders have been studying about the theory of plate tectonics. Of the following statements, which ones would be the BEST conclusion to the lesson?
There are small amounts of movement at the plates' edges.
There is no geologic activity located at the plates' edges.
Geologic activity causes stress to build and storage of energy at the edges.

Abigail and David are working on a school project about Earth's geology. They need to identify which combination of the following theories was most directly responsible for the development of the Theory of Plate Tectonics. Can you help them?

Seafloor Spreading as proposed by Harry Hess

Maya and her friends are studying Earth’s magnetic field and learn that it has North and South poles that have reversed themselves many times in the past. They discover that these reversals are recorded in rocks forming along mid-ocean ridges. These facts most closely correlate to which of the following Scientific Theories?
Continental Drift as proposed by Alfred Wegener
Seafloor Spreading as proposed by Harry Hess
Geologists found that rock samples from the Appalachian Mountains in North America and the Scottish Highlands in Europe were identical in age and composition. This finding supports the theory of —
volcanic activity
plate tectonics
tidal forces
climate change
During a school science project, Avery and Aria were tasked with proving that the plates containing continents and ocean floor are always moving. What documented proof did they find?
Most scientists did not believe Wegner because he was a meteorologist and could not prove how the continents moved. But, Hess and Dietz were geologists so the public and the scientific community gave them support in their conclusions.
The bathymetric dating and mapping of the ocean floor found younger rock near mid-ocean ridges and the ocean crustal material near continents contained older rock.
The discovery of similar fossils on different continents.
The observation of similar mountain ranges on different continents.
What insights can scientists gain about Earth's future by examining the movement of tectonic plates?
They can determine the exact number of species that will exist in the future.
They can predict the future positions of continents and oceans if current plate movements persist.
They can identify the only time period when continents moved and similar fossils were found.
They can understand the development of human theories on continental drift and plate tectonics.
What type of geological feature is typically formed at a divergent plate boundary?
Trench

convergence, landslides
What type of landform is typically created by the collision of two continental plates?

to the left of A
between D and E
to the right of E
between A and B
Hotspots are volcanoes that form...
at convergent plate boundaries.
at divergent plate boundaries.
at transform plate boundaries.
in the middle of a tectonic plate.
This image shows the hawaiian island change. Hawaii is currently the tallest island and is still an active volcano. Based on the map chose the answer that best explains the age of the islands.
The further the islands are from Hawaii the younger the island is.
Hawaii is the youngest island because it is currently on top of the hotspot.
Hawaii is the oldest island because it is closest to the hotspot.
Ohau is younger than the big island because it is further from the hot spot.
Volcanoes usually form near

How did the Appalachian Mountains form?
Folded mountains occur when two plates of the Earth's crust
separate.
Folded mountains are the result of many volcanoes erupting all
at the same time.
Folded mountains form over millions of years as sediments are
deposited and build up.
Folded mountains occur when two plates of the Earth's crust
push against each other.
