[Answer] A body of gneiss is subjected to heat and forms a melt. Later the melt cools and crystallizes to form a (n) ________ rock.

Answer: igneous
A body of gneiss is subjected to heat and forms a melt. Later the melt cools and crystallizes to form a (n) ________ rock.
Igneous rock (derived from the Latin word ignis meaning fire) or magmatic rock is one of the three main rock types the others being sedimentary and metamorphic.Igneous rock is formed through the cooling and solidification of magma or lava.. The magma can be derived from partial melts of existing rocks in either a planet’s mantle or crust.Typically the melting is caused by one or more of …
Metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks () without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat pressure and the introduction of chemically active fluids. The chemical components and crystal structures of the minerals making up the rock may change even …

Tue Jul 26 2005 14:30:00 GMT-0400 (Eastern Daylight Time) ยท The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary metamorphic and igneous.Each rock type is altered when it is forced out of its equilibrium conditions. For example an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere or melt as it is subducted under a continent.
Within the field of geology Bowen’s reaction series is the work of the petrologist Norman L. Bowen who summarized based on experiments and observations of natural rocks the sequence of crystallization of common silicate minerals …
