Which of the following is the most likely global climate change? a. a decrease in the overall temperature of the earth b. an increase in the overall temperature of the earth c. an increase in the number of cold climates d. no change to global climate

An increase in the overall temperature of the earth, so B

The global climate change currently is primarily due to the increase in the emission of the greenhouse gases that trapped the ultraviolet rays. With this phenomenon, Earth gets more heated up. Thus, the answer to the question above is letter "B. an increase in the overall temperature of the Earth". 

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.

The answer is    d.  central highlands
