Sea Floor Closest To Center Of Earth
B the earth s polar radius or semi minor axis is the distance from its center to the north and south poles and equals 6 356 750 km 3 949 901 mi.
Sea floor closest to center of earth. The point closest to the earth s centre 6 353 km 3 948 mi is probably at the bottom of the arctic ocean greatest depth 5 450 m 17 881 ft near the geographic north pole the bottom of the mariana trench is 6 366 4 km 3 956 mi from the centre of the earth the radius of the earth at the poles is 6356 75km. In other words if you could dig a hole 6 371 km you d reach the center of the earth. Mauna kea hawaii 10 203 m from submarine base to peak. Deep ocean drilling and radiometric dating in the late 1960s gave an accurate stratigraphy and precise date of the ocean floor.
Caption the average distance to the centre of the earth is 6 371 km or 3 959 miles. A multimillion dollar project is getting closer to our planet s center and could unlock some of earth s longest held secrets. From studying the oxygen isotopes of the shells of microfossils in these cores scientists were able to begin studying the earth s past climates in a study known as paleoclimatology. It says that some parts of the arctic sea bed are closer but no one has attempted any explorations to this area.
At the equator it is 6378 14km. Lowest point on land. The summit of chimborazo is 20 564 feet above sea level. Aug 31 15 7 22 am.
Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. It does say the marianas trench is not part of a sea floor closest to earth s center because the earth is not a perfect sphere. Dead sea shore israel 395m below sea level.
The ocean floor isn t flat. The distance from a place such as a beach would be vastly different from say challenger depths. Of the 15 million year old region of the pacific ocean floor. In the 1960s the past record of geomagnetic reversals of earth s magnetic field was noticed by observing magnetic stripe anomalies on the ocean floor.
At this point you. Earth is not a perfect sphere but is a bit thicker at the equator due to the centrifugal force created by the planet s constant rotation. Because of this the highest point above earth s center is the peak of ecuador s mount chimborazo located just one degree south of the equator where earth s bulge is greatest. 9 10 this results in broadly evident stripes from which the past magnetic field polarity can be inferred from data gathered with a magnetometer towed on the sea surface or from an aircraft.
