Commonly these come from a submarine hills or glaciers. (See image), In the same way that water moves upwards through a tube against the force of gravity; water moves upwards through soil pores, or the spaces between soil particles. In addition to the resources on theEvent Supervisors page, Dynamic Planet Event Supervisors should be sure to use the following resources: 1999-2022 Science Olympiad Inc., a 501(c)(3) non-profit A depression produced in a region where soluble rock has been removed by groundwater, A kind of sinkhole that forms when water dissolves the surface rock, creating a depression; they occur in areas where limestone is exposed at the surface or is covered by thin layers of soil or sand. It depends on wind patterns in the atmosphere. The subtraction of wave energy as waves meet producing smaller waves.
