Final answer:
Earthquakes are majorly triggered by tectonic movements happening naturally within the earth's crust, primarily through processes such as volcanic eruptions, continental drift, and mountain building. Human activities like seismic exploration or building construction can cause minor tremors, but strong earthquakes are natural phenomena. Deep-sea diving expeditions or lunar exploration missions do not cause earthquakes.
Step-by-step explanation:
Earthquakes occur due to the release of built-up stress within the Earth's crust, predominantly caused by the movement of tectonic plates. These geological activities take place in various settings. Let's explore some of these.
Volcanic eruptions are also a common cause of earthquake activity. When magma rises towards the Earth's surface, it disrupts the crust and often causes seismic activity. This is evident in how the movement of magma under the Earth's crust was responsible for the creation of the Hawaiian island chain.
Additionally, continental drift and related activities like mountain building can trigger earthquakes. For instance, as tectonic plates slowly move and collide into each other, they form mountains and cause significant changes in the Earth's crust over time, which can result in earthquakes.
However, activities such as deep-sea diving expeditions, construction of tall buildings and lunar exploration missions do not directly cause strong earthquakes. These are generally influenced by natural forces, including tectonic movements and volcanic activities.
