That statement would be true

By definition , climate is a weather condition  that prevail in a specific are for a long period of time

They do that to find out what cause the climate and what effect that the climate do to everything around them

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
