The Indian Ocean floor map drains the water away and leaves the bathymetry exposed: the long spine of the Mid-Indian Ridge, the arrow-straight Ninetyeast Ridge, the Java Trench running below Sumatra and Java, the sediment spread of the Bengal Fan, and the shallow shelf of the Mascarene Plateau. Strong tonal contrast separates abyssal basins from ridges and rises, so the tectonic story of the basin reads at a glance rather than needing a lecture to explain it.
