If earth were either all land or all water and did not rotate on its axis‚ a large convection cell would form in each hemisphere with the colder and denser air at the poles sinking to the surface and flowing toward the tropics.

This rotation causes the Coriolis effect‚ wherein moving particles such as

Genetically modified Papayas started back in 1990 in Hawaii when the entire crop was infected with the ringspot virus‚ the entire papaya industry was in danger.

hexamerous symmetry (i.e.‚ parts in multiples of 6). The most familiar group of corals‚ the reef builders‚ includes around 650 extant species (i.e.‚ around half the known stony coral species). These are found mostly in the clear‚ shallow waters of the tropics. They are distinguished from the other subclass of Anthozoa‚ Octocorallia‚ in having six or fewer lines of symmetry in their body structure and only single rows of tentacles. These organisms are formed of individual soft polyps which in some live
