Most magma forms from the partial melting of Earth's mantle rocks. As these rocks are subjected to high temperatures and pressures in the mantle, certain minerals melt at different temperatures, leading to the formation of magma.
When magma cools slowly, it forms igneous rocks such as granite or diorite, which have large mineral crystals because they had time to grow as the magma solidified.
The melting of metamorphic or igneous rock forms magma, which can eventually cool and solidify to form igneous rock.
When magma cools and solidifies, it forms igneous rocks such as granite, basalt, or obsidian. The specific type of rock that forms depends on variables such as the composition of the magma, cooling rate, and environment in which it solidifies.
The molten material deep inside Earth is called magma. When magma cools and solidifies, it forms igneous rock.
Gaseous thick magma equals massive explosion.

Pahoehoe lava
The most abundant type of magma erupted at oceanic spread centers is basaltic magma. This type of magma has low viscosity and forms in the mantle part of the Earth that are high in iron and magnesium.
The rock melts, just like most other solids do when heated. Magma is to rock as water is to ice.
Most magma originates in the asthenosphere, which is a semi-fluid layer located in the upper mantle. Magma forms here due to the high temperatures and pressures that facilitate the melting of rock.
Lava and magma are two forms of melted rocks
Granite and basalt are made when magma cools. Granite forms from slow-cooling magma underneath the Earth's surface, while basalt forms from rapidly-cooling magma on the surface.
The magma forms sills and magma chambers.

False. It forms in the Athenosphere!!
Yes magma cools down and forms a harder rock.
