If a geographer is studying a volcano,

1. the volcano is the result of the physical process
2. the volcano is the cause of the physical process
3. the volcano had no relationship to the physical process
4. the volcano sometimes affects the physical process

The Correct Answer is 1. The volcano is the result of the physical process

Explanation:

The physical processes are responsible for the shape of the earth's surface and the formation of landforms, the physical processes can be Wind, Rain, Volcanism, Glaciation, Erosion or even tectonic movement. Volcanos themselves are Landforms resulting from Physical processes such as tectonic movements where Subduction pushes the magma on the Inner Core of the Earth to the surface until the magma comes out from the Earth’s crust, making a volcano vent and depending on the pressure the volcano can grow bigger and wider.

If we were to analyze the volcanic explosion, then the volcano is considered as the cause.
