Question

question 9
how do igneous rocks typically form?
through the cooling and solidification of magma or lava
through the accumulation of sediments
through precipitation of minerals
through metamorphosis of existing rocks

Explanation:

Igneous rocks are formed from the cooling and solidification of magma (beneath the Earth's surface) or lava (on the Earth's surface). Sediment accumulation forms sedimentary rocks, mineral precipitation can be part of sediment - formation or hydrothermal processes, and rock metamorphosis forms metamorphic rocks.

Answer:

Through the cooling and solidification of magma or lava
