Which of the following best defines base isolation?(1 point)
Responses

Base isolation is a technique used to prevent damage to buildings during tsunamis. The main structure of the building is separate from the base, which allows water to pass beneath buildings without causing much damage.

Base isolation is a technique used by engineers to help prevent damage to buildings by earthquakes. The main structure of the building is separate from the base and sits on a bed of springs.

Base isolation is a technique used to prevent large-scale damage from volcanoes. New communities being built are set as far back as possible from the base of a volcano.

Compare and contrast earthquakes and tsunamis.(1 point)

Earthquakes and tsunamis both occur in the ocean. However, only earthquakes affect humans.

Earthquakes and tsunamis are both caused by the movement of tectonic plates. Tsunamis only affect islands, while earthquakes only affect landlocked regions.

Earthquakes and tsunamis are both caused by the movement of tectonic plates. The damage an earthquake causes is due to the shaking of the plate, whereas the damage a tsunami causes is due to the large wave that is created by the shaking plate.

In one or two sentences, explain two impacts that earthquakes can have on humans.(2 points)
Earthquakes can result in building collapse, leading to injury or death, and can also cause infrastructure damage, such as roads and bridges, disrupting transportation and communication systems.
In one or two sentences, explain what the main impact tsunamis cause on humans. Why is it difficult to avoid a tsunami?(2 points)
Tsunamis can cause massive flooding, leading to destruction of coastal communities and the loss of lives. It is difficult to avoid a tsunami because they travel very quickly across the ocean and can be triggered by underwater earthquakes or volcanic eruptions, leaving very little time for evacuation.
