Jessica is traveling from Miami, Florida, to Chicago, Illinois. Using the map, tell one way the land will change during the second half of her trip? A. The elevation will drop below sea level.
B. The elevation will gradually decrease.
C. The elevation will gradually increase.
D. The elevation will remain the same.

I would say a, by the coast the elevation is above the sea level due to it being so close to the water so moving more inland would likely decrease this elevation.

5×^2+20-15 or -(5x^2-20+15)

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.
