Answer: 1. through the freezing or crystallization of a melt

Explanation: Igneous rock is formed through the freezing and solidification of magma. The magma are from partial melts of existing rocks in the Earth's crust. Basically, the melting is caused by an increase in temperature, a decrease in pressure, or a change in composition.
