You are presented with two maps that cover the same area (e. g., Dallas, TX) with one using a 1:50 scale and the other using a 1:1500 scale, which map would be
bigger in person? Why?

Since wxyz is 4, halfof that would be 2.

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.
