Which of the following is an effect of an earthquake?

The correct answer encompasses a variety of phenomena associated with earthquakes. When an earthquake occurs, it typically results from the movement of tectonic plates along fault lines, causing significant shifts in the Earth's crust. This is the fundamental cause of earthquakes and is integral to understanding seismic events.

Additionally, earthquakes can generate tidal waves, more commonly referred to as tsunamis, particularly when they occur beneath the ocean. The sudden displacement of water caused by the seismic activity can create large waves that can travel vast distances, leading to devastating impacts on coastal regions.

Landslides are another significant effect of earthquakes, especially in areas with steep terrain. The seismic shaking can dislodge rocks and soil, causing them to cascade down slopes, which can destroy infrastructure, block roads, and lead to further hazards for nearby communities.

Given these interconnected effects, selecting all of the above provides a comprehensive understanding of the possible consequences of an earthquake, highlighting the complexity and far-reaching impacts associated with these geological events.
