E  Boston, Honolulu

A  Carved into the rocks were inscriptions of past tsunamis and bat dropping showing the bats could not land under the wave.

B  The waves left the remains of whales high up on the local mountains and ripped vast boulders from off the ocean floor and dropped them on land.

C  Huge waves reshape some of the islands, blasting the chevron shaped ridges. The waves also ripped vast boulders from off the ocean floor and dropped them on land.

D  Huge waves reshape some of the islands, blasting the chevron shaped ridges. The waves also left the remains of whales high up on the local mountains.

A  Yes

B  No

A  The way they formed

B  The amount of lightning

C  The weight of the rocks in the area

D  The overall temperature

E  The frequency of rainfall

A  Glaciers

B  Volcanic islands

C  Harbors

D  Tropical beaches

E  River valleys

A  They were testing earthquakes that generate megatsunamis, they physically model an earthquake’s impact on the water

B  They were testing landslides that generate megatsunamis, they physically model a landslide’s impact into water

C  They were trying to predict the next time a volcano will erupt in the Canary Islands

D  They were testing to see how long a landslide will occur before it hits the water

E  They were trying to see if landslides could cause tsunamis

A  They are more common than seismic tsunamis

B  Seismic tsunamis offset the water upwards which means they are limited in height, landslide tsunamis offset the water all the way to the bottom so their height is limited only by the depth of the ocean, which, can be thousands of meters

C  False, landslide tsunamis are not a greater threat

D  Seismic tsunamis have to remain in the local area and landslide tsunamis travel over the whole ocean

E  Seismic tsunamis travel at a slower speed than landslide tsunamis

A  By volcanoes erupting and pushing ash into the ocean

B  By the up and down motion of rocks during earthquakes offsetting the water

C  By landslides hitting the ocean and pushing the water away

D  By lateral movement of rocks breaking during earthquakes offsetting the water

A  By aerial surveillance

B  By eyewitness accounts of another tsunami

C  By historical documents

D  By seismic data

A  There was oil deposits beneath the trees

B  A violent force had hit the trees at some point in the past

C  Gold dredging was common there

D  Earthquakes were common in the area
