Oasis biology experiment surface area volume

On Twitter recently, I saw the following tweet: I describe it below. The trick plays on the idea that people think water will drain or flush in a toilet one way north of the equator, and the other way south. All you need to know is that over the size of a water basin, the Coriolis force has no effect.

Geography[ edit ] Seamounts can be found in every ocean basin in the world, distributed extremely widely both in space and in age.

Overall, seamount and guyot coverage is greatest as a proportion of seafloor area in the North Pacific Ocean, equal to 4.

The Arctic Ocean has only 16 seamounts and no guyots, and the Mediterranean and Black seas together have only 23 seamounts and 2 guyots. The largest three guyots are all in the North Pacific: Seamounts are often found in groupings or submerged archipelagosa classic example being the Emperor Seamountsan extension of the Hawaiian Islands.

Formed millions of years ago by volcanismthey have since subsided far below sea level. This long chain of islands and seamounts extends thousands of kilometers northwest from the island of Hawaii.

Distribution of seamounts and guyots in the North Pacific Distribution of seamounts and guyots in the North Atlantic There are more seamounts in the Pacific Ocean than in the Atlantic, and their distribution can be described as comprising several elongate chains of seamounts superimposed on a more or less random background distribution.

Craig and Sandwell [5] noted that clusters of larger Atlantic seamounts tend to be associated with other evidence of hotspot activity, such as on the Walvis RidgeBermuda Islands and Cape Verde Islands.

The mid-Atlantic ridge and spreading ridges in the Indian Ocean are also associated with abundant seamounts. Isolated seamounts and those without clear volcanic origins are less common; examples include Bollons SeamountEratosthenes SeamountAxial Seamount and Gorringe Ridge.

Pillow lava Click to enlarge. Most seamounts are built by one of two volcanic processes, although some, such as the Christmas Island Seamount Province near Australia, are more enigmatic. The lower density magma rises through the crust to the surface. Volcanoes formed near or above subducting zones are created because the subducting tectonic plate adds volatiles to the overriding plate that lowers its melting point.

Which of these two process involved in the formation of a seamount has a profound effect on its eruptive materials. Lava flows from mid-ocean ridge and plate boundary seamounts are mostly basaltic both tholeiitic and alkalicwhereas flows from subducting ridge volcanoes are mostly calc-alkaline lavas.

Compared to mid-ocean ridge seamounts, subduction zone seamounts generally have more sodiumalkaliand volatile abundances, and less magnesiumresulting in more explosive, viscous eruptions. The first stage of a seamount's evolution is its early activity, building its flanks and core up from the sea floor.

This is followed by a period of intense volcanism, during which the new volcano erupts almost all e. The seamount may even grow above sea level to become an oceanic island for example, the eruption of Hunga Tonga. After a period of explosive activity near the ocean surfacethe eruptions slowly die away.

With eruptions becoming infrequent and the seamount losing its ability to maintain itself, the volcano starts to erode. After finally becoming extinct possibly after a brief rejuvenated periodthey are ground back down by the waves.

Seamounts are built in a far more dynamic oceanic setting than their land counterparts, resulting in horizontal subsidence as the seamount moves with the tectonic plate towards a subduction zone. Here it is subducted under the plate margin and ultimately destroyed, but it may leave evidence of its passage by carving an indentation into the opposing wall of the subduction trench.The volume of a cell determines the needs of that cell for oxygen and other resources, as the metabolism increases according to the volume of cytoplasm.

The surface area controls the rate of uptake of the oxygen. This experiment shows the effect of increasing size on the rate of diffusion of materials into and out of the cytoplasm of a cell. This bar-code number lets you verify that you're getting exactly the right version or edition of a book.

Perhaps lunar miners could use something analogous to Bruce Damer's idea for asteroids of using CO in an enclosure warmed by the sunlight and iron and nickel extracted in attached 3D printer - .

In Part 3, they conduct experiments based on the principles of osmosis. In Part 4, they investigate the effect of surface-area-to-volume ratio on the rate of diffusion. A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (), and thus is not an island, islet or r-bridal.comnts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,–4, m (3,–13, ft) in height.

They are defined by oceanographers as independent features that rise to at.
