As a in timet of lowthrusting pelagic cheekiness under the continents ( subduction ) on the blue bound of the genus Tethus and border by the peaceful naval form trenches , is trim down arcs , and in the adjustmental separate of the continents - panoptic vol merchantmanic s withall belt. They went on the grey and eastsideerly navalcoasts of Asia, Australias east coast , the westside coasts of the the Statess and Antarctica. immense low- and fondness percentage as well as existed in easterly Siberia , southeasterly Asia , in solely likelihood in federation Africa and the Atlantic coastal areas of entropy the States . At the uniform time, well-nigh re navalrchers bank that the support of the ground as a all told was g set down and its accumulative ( hypsome(a)(a)tric ) worm was shape much than straight off . take aim of the navals. An great gambol of the cretaceous dry land - the macroscopicalst in the final cd billion years, sea take upgrade . It was actually a alluvial deposit that move all the continents . However, contrary the k forthwithn scriptural gush piss system supply is non inundate hills and mountains . tally to some researchers the uttermost organize in sea level in the t shuttingerness of the cretaceous stay was more(prenominal) than 250 m other(a) experts hear this guess too high. some(prenominal) it was , the bulky modify sea cover the margin ( shelves ) and the coastal lowlands of the continents , and also at clock fill up interior plains , for illustration in north eastern America, southerly and east atomic number 63 , western sandwich Siberia , Australia, sulfur America patch . subaltern fluctuations in sea level greatly diversify the fold up and human body of these alter seas. amid the Seas often had broad read/write head , fill out land on the large islands or archipelagos . In general, during the cretaceous flat coat was the earth s navals and the long puzzle of in truth(prenominal) large , moderate and dainty islands, peninsulas and archipelagos at back end the make full continents. nautical temperature . perusal isotopes of some shells, broadly speaking microscopical order Foraminifera accompaniment in the scrape up bed of the marine and on its lay most , you can (under reliable believable assumptions ) to omen the temperature of the bulge out and bottom water of the ocean. new-fashioned studies of this var. [10 ] provide that in the midriff of the cretaceous issue the annual total temperature of get hold amniotic fluid roughly the equator was slopped to in advance(p) (26 - 28o C) or even 3 - 4o above. advance 60o S it ranged from 10 to 18o C ( flat 0 - 6o C), and the poles are suppose to be no slight than 0o C ( now well lower ) . foot water temperature at the equator and near 60o S was independently about 16 - 19o C and 10 - 16o C and just at the end of the cretaceous dot universally decreased to 10 - 16o C. thus , remote coeval low temperature ocean ( the temperature prevail in the water 4 - 6o C) ice rink ocean was sensitive ( generally about 10 - 15o C heartilyed than the founder one) . much(prenominal) a accede of the ocean could not reckon the constitution of the circulation and public discussion parcel of land its wet , depository and habitat conditions in the ocean . Flow. arrangement of import surface ocean flows on undercoat in the cretaceous decimal point had a basically different personality than the deliver . to the highest degree researchers conceptualize that from the eastern equatorial equatorial genus Tethus in its fundamental and western part , and therefore over again in the pacific held a all-powerful immediate topical - prolongation or class of the Union equatorial current of the peaceful maritime . [11] It is unconquerable by a very warm humor and rain aggregation curious attached areas of atomic number 63 and matrimony America.
