This method is commonly used for metals like aluminum and sodium, which cannot be reduced by carbon due to their high reactivity.

If magma reaches the Earth's surface before crystallizing, it erupts as lava. As the lava flows and cools, it solidifies into igneous rock, often forming features like volcanic landforms. The rapid cooling can lead to different textures in the rock, such as glassy or fine-grained structures, depending on the cooling rate and composition of the lava. Additionally, gases trapped in the magma can escape during the eruption, sometimes creating explosive volcanic activity.

Circulation refers to the movement of substances within a system.
