Question

A change in the temperature of the core would affect all of the following except:

Answer 1

Answer is D: the current make up of the crust

Changes in the temperature of the Earth's core will do the following:
1. Cause the outer core to solidify 
-this means that the liquid outer core which is responsible for generating the magnetic field protecting us humans from solar radiation will be gone

2. Cause the mantle to solidify
-this means that if the mantle solidifies, the plate tectonics will stop moving around, and if this happens, the earthquakes and volcanoes will not be produced anymore and also mountain ranges will not be renewed, and the earth will be flattened by erosion.
