Which correctly identifies ways that earthquakes and tsunamis can cause destruction?
a. earthquakes:erosion of beaches tsunamis:move blocks of land up or down
b. earthquakes:landslides tsunamis:move blocks of land up or down
c. earthquakes:landslides tsunamis:open up large cracks in earths crust
d. earthquakes:open up large cracks in earth's crust tsunamis:erosion of beaches
c. earthquakes:landslides tsunamis:open up large cracks in earth's crust
The correct answer is:
c. earthquakes: landslides tsunamis: open up large cracks in the earth's crust
The correct option that identifies ways that earthquakes and tsunamis can cause destruction is option (b): earthquakes can cause landslides, while tsunamis can move blocks of land up or down.
Explanation:
When it comes to earthquakes, they can trigger landslides. Earthquakes generate powerful vibrations in the ground, which can cause the destabilization of hillslopes or steep slopes, leading to landslides. These landslides can, in turn, cause significant destruction to buildings, infrastructure, and other structures on the affected slopes.
On the other hand, tsunamis are large ocean waves that are typically caused by undersea earthquakes. When a powerful earthquake occurs under the ocean, it can displace a massive amount of water, generating a tsunami. As the tsunami approaches the coast, it can force the movement of large blocks of land either upwards or downwards, leading to the destruction of coastal structures and landscapes.
Therefore, option (b) is the correct choice as it accurately describes the destructive effects caused by earthquakes and tsunamis.
