A  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.

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

C  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.

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 overall temperature

E  The weight of the rocks in the area

A  Tropical beaches

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

B  They were trying to see if landslides could cause tsunamis

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

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

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

A  Seismic tsunamis travel at a slower speed than landslide tsunamis

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

C  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

D  They are more common than seismic tsunamis

E  False, landslide tsunamis are not a greater threat

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 lateral movement of rocks breaking during earthquakes offsetting the water

D  By landslides hitting the ocean and pushing the water away

A  By eyewitness accounts of another tsunami

B  By historical documents

C  By seismic data

D  By aerial surveillance

A  Gold dredging was common there

B  There was oil deposits beneath the trees

C  Earthquakes were common in the area

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