What do earthquakes and tsunamis have in common?(1 point)
They only occur on landmasses.
They only occur on landmasses.
They originate on Earth’s surface.
They originate on Earth’s surface.
They modify Earth’s surface.
They modify Earth’s surface.
They only occur in the ocean.
They originate on Earth's surface.
To determine the correct answer, let's analyze each option:
1. "They only occur on landmasses": This option is incorrect because both earthquakes and tsunamis can occur both on land and in the ocean.
2. "They originate on Earth’s surface": This option is correct. Both earthquakes and tsunamis originate on the Earth's surface. Earthquakes are caused by the release of energy in the Earth's crust, while tsunamis are typically generated by undersea earthquakes or volcanic eruptions.
3. "They modify Earth’s surface": This option is correct. Both earthquakes and tsunamis have the potential to modify Earth's surface. Earthquakes can cause the ground to shake, resulting in changes to the landscape, such as cracks in the ground or landslides. Tsunamis, on the other hand, can cause severe erosion and deposition of sediment, altering coastlines.
4. "They only occur in the ocean": This option is incorrect because earthquakes and tsunamis can occur both in the ocean and on land. In fact, tsunamis can be generated by undersea earthquakes and then travel across the ocean, potentially impacting coastal regions.
Based on the analysis, the correct answer is: "They originate on Earth’s surface" and "They modify Earth’s surface."
