Detailed explanation-1: -There are basically 2 types of changes that occur to the earth’s surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process.

Detailed explanation-2: -Earthquakes, volcanoes, tsunamis and landslides are naturally occurring events that can rapidly change Earth’s surface.

Detailed explanation-3: -The primary effects of earthquakes are ground shaking, ground rupture, landslides, tsunamis, and liquefaction. Fires are probably the single most important secondary effect of earthquakes.

Detailed explanation-4: -Earthquakes often cause dramatic changes at Earth’s surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mudflows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures.
