The reason we use convolution is because we consider the earth to be a linear, time-invariant, passive system. The output of any such system is the convolution of the input and the impulse response of the system. "linear" means that if input x (t) produces output X (t) and input y (t) produces output Y (t), then input Ax (t)+By (t) produces ...
