If a new, large continent formed at a tidal amphidromic point, which consequence follows?

A)Global tidal range would increase
B)Tidal wave propagation would shift
C)Erosion rates on coasts decrease
D)Ocean salinity gradients would vanish

💡 Explanation

Tidal amphidromic points are locations of zero tidal amplitude; therefore, the placement of a continent there would alter the cotidal lines radiating outwards because it changes the basin geometry influencing tidal wave propagation, rather than causing other effects.
