The plate formed because the triple junction had converted to an unstable form surrounded on all sides by transform faults, due to the development of a kink in one of the plate boundaries. The "Pacific Triangle", the oldest part of the Pacific plate, created during the initial stages of plate formation, is located just east of the Mariana ...
Drake found the bay unexpectedly, as by godsend and "fell with" a harbor within the bay. 9. The bay faces south, with depths from six to eight fathoms within a prominent point, diminishing gradually to three fathoms on a course leading northeasterly into the bay toward an anchorage off a river or estuary in the north end.
Relative velocity vectors of Pacific, Farallon, and Kula plates 55 million years ago (Black represents present-day land area). The Pacific-Farallon Ridge was a spreading ridge during the Late Cretaceous that extended 10,000 km in length and separated the Pacific Plate to the west and the Farallon Plate to the east.
The Point Reyes Peninsula is on the Pacific Plate, while the rest of Marin County land is on the North American Plate. [33] The peninsula is a member of the Salinian Block , a segment of the southernmost Sierra Nevada range transported north from Southern California by movement along the San Andreas fault. [ 34 ]
The East Pacific Rise near Easter Island is the fastest spreading mid-ocean ridge, with a spreading rate of over 15 cm/yr. [2] The Pacific plate moves generally towards the northwest at between 7 and 11 cm/yr while the Juan De Fuca plate has an east-northeasterly movement of some 4 cm/yr. [3]
The presence of the Drake Passageway allows the three main ocean basins (Atlantic, Pacific and Indian) to be connected via the Antarctic Circumpolar current (ACC), the strongest oceanic current, with an estimated transport of 100–150 Sv (Sverdrups, million m 3 /s). This flow is the only large-scale exchange occurring between the global oceans ...
Devorsine — who makes the return journey about six to eight times per year — estimates that the unusually calm “Drake lake” effect happens once in every 10 crossings, with particularly ...
The Englishmen vowed when they saw the Pacific Ocean that one day they would sail its waters [58] – which Drake would do years later as part of his circumnavigation of the world. [ 59 ] When Drake returned to Plymouth after the raids, the government signed a temporary truce with King Philip II of Spain and so was unable to acknowledge Drake's ...
