The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.
Emigration is aEarthquake is a density-independent limiting factor since the reason for an earthquake to happen is because of natural phenomena such as the drifting or the natural tectonic movement of the plates of the continents and islands. In this case, the population has nothing to do with earthquakes
Answer: 1) destroys animal habitats and causes topsoil to erode- deforestation
2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground
3) harms aquatic creatures and vegetation- oil spills during transport on a ship
