To answer this question, we need to understand what earthquakes and tsunamis are and what they have in common. Earthquakes are caused by the sudden release of energy in the Earth's crust, resulting in seismic waves that can shake the ground. Tsunamis, on the other hand, are sea waves that are usually triggered by underwater earthquakes or volcanic eruptions.
Looking at the responses provided, we can eliminate the options that are incorrect. "They only occur in the ocean" and "They only occur on landmasses" are not accurate statements because earthquakes and tsunamis can occur both in the ocean and on land. Earthquakes can occur anywhere on Earth's surface, and tsunamis can be generated in the ocean but can also make landfall and affect coastal areas.
The remaining options are "They originate on Earth's surface" and "They modify Earth's surface." Both of these statements are true for earthquakes and tsunamis. Earthquakes originate on the Earth's surface, specifically along fault lines where tectonic plates meet. Tsunamis are also caused by events that occur on the Earth's surface, such as underwater earthquakes or volcanic eruptions. Both earthquakes and tsunamis can cause significant changes to the Earth's surface due to the powerful forces involved.
Therefore, the correct answer to the question is: "They originate on Earth's surface" and "They modify Earth's surface."
