Convection currents and the movements of the crust.
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
Factors that determine the force of an eruption are magma viscosity and gas content.
The ingredients required to form an igneous rock are molten or partially molten material called magma or lava. This magma or lava consists of various minerals and volatiles such as water, carbon dioxide, and sulfur. The environmental factors that contribute to the formation of igneous rocks include high temperatures, pressure changes, and rapid cooling or solidification of magma or lava.
Areas of volcanic activity that develop above rising plumes of magma are called hot spots.
Temperature, among other factors, effects the viscosity(thickness) of magma. However, for the most part, the temperature of magma is relatively consistent because magma is the type of molten rock that has not yet exited the volcano, so there are fewer factors to effect the temperature.

Geothermal activity is activity which happens deep down underground in the Earth. It can be like the magma rising when a volcano is erupting or about to erupt.

Lava is the name for molten rock that appears at or near the surface from volcanic activity.
Intrusive activity is when magma in the mantle or crust starts to cool and crystallize. Igneous rock forms from the crystallization.
Rate of cooling of the magma and Chemical composition of the magma.
The force of a volcanic eruption is affected by many factors. They include, viscosity of the magma, its temperature, amount of gas content, and the size of the magma reservoir.
convection currents. Causes the magma to move the earths crust creating plate movement.
