When magma reaches the surface it is then called lava and the eruptions of lava and ash produce volcanoes. The lava that reaches the Earth's surface will harden and become igneous rock. ... These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers.
Because latitude are lines in a numerical way to measure how far north or south of the equator a place is located. So it is NOT a climate of a region... if that makes sense lol.
