The shape tells a geologist how viscous (thick and sticky) the lava was. A taller volcano, such as a cone, was formed by thicker lava; a low volcano, such as a shield volcano, was formed by very runny lava.
Before a volcano erupts, there may be high frequency and low frequency earthquakes, changes in shape or size of the volcano, and tremors.
When the volcano erupts, lava comes out and hardens on the surface of the volcano. If the volcano keeps erupting, then the hardened lava will create layers which cause the volcano to get taller like a mountain.
The Komagatake volcano in Japan is classified as a stratovolcano. The definition of a stratovolcano is a volcano that is conical in shape and composed of layers of material expelled from previous eruptions.
The opening at the surface of the Earth through which volcanic material passes is called a vent. Vents can vary in size and shape, and they are typically found at the top of a volcano or along a fissure during an eruption. Magma rises through the vent and erupts onto the surface as lava, ash, and gas.
A cinder cone volcano can form relatively quickly, typically in a matter of a few months to a few years. This type of volcano usually erupts intermittently, with each eruption depositing layers of ash, cinder, and lava that build up the cone shape over time.

A volcano shapes the earth because when a volcano erupts, the lava hardens, forming new land on the earth's surface
The typical cone shape of a volcano happens when sticky lava erupts upward. Sticky lava creates a dome shape and the lava cools slowly.

Before a volcano erupts, there is normally an increase in earthquakes, you might see some volcanic ash come out, you might see an increase in gas or steam around the volcano, and you might see a change in height or shape of the land around the volcano.

This describes a stratovolcano, also called a composite volcano.
