Fish is cold blooded animal

yes, they are. Fish are cold-blooded vertebrates that live in water, breathe with gills, and have fins rather than legs. Cold-blooded means their surrounding environment largely regulates their body temperature.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
