Major sea floor topographic features and plate tectonic concepts such as continental
drift and sea floor spreading are illustrated with this versatile model. When submersed
in an aquarium, it is designed to simulate rift vent and volcanic eruptions using air
bubbles. It can also simulate deep sea properties such as turbidity, salinity, convection,
and upwelling currents using colored dye in salt or cold water. The sea floor model is
made of a durable waterproof plastic and it comes with air bubble lines with connectors,
suction cups, profile decals, vocabulary decals, and a teacher’s guide with three lessons
and student worksheets. Requires a ten gallon tank and aquarium pump, available
separately. Size of model: 19”L x 9”W x 6”H.
