As the shadow of a tower decreases, the sun gets higher in the sky, moving closer to being directly overhead. Trigonometrically, $\tan \theta = \frac{\text{Height}}{\text{Shadow length}}$. Since the height is constant and the shadow length decreases, the value of $\tan \theta$ increases, which means the angle of elevation $\theta$ increases.
