The first approximation of the Bouguer gravity anomaly relation is Hkm = 35 (1th 0.0037 g), Hkm being the crustal thickness and g the Bouguer anomaly.--C. E. Sears.doi:10.1080/00206816309473864Gaynonov, A. G.Smirnov, L. P.Taylor & Francis GroupInternational Geology Review...
Ocean tideshave the same frequencies as solid Earth tides, but they derive from both the vertical and (small) horizontal components of the TGP that generates water movement in shallow areas such as thecontinental shelves. This variable water depth loads the crust and modifies the amplitudes of th...
Structure and thickness of the Earth’s crust in the northeastern part of the Indian Ocean A digital database on the seismostratigraphy of the oceanic crust of the northeastern part of the Indian Ocean is compiled. In the first layer of the crust... AA Schreider,EL Mazo,MP Kulikova,......
The crustal accretion along mid-ocean ridges is known to be spreading-rate dependent. Along fast-spreading ridges, two-dimensional sheet-like mantle upwelling creates relatively uniform crust. In contrast, the crust formed along slow-spreading ridges sho
Even as you read this, Earth's crust is continually being reborn and recycled in a dynamic process that fundamentally shapes our planet. We're not generally aware of all this action because most of it occurs at the seafloor, under a formidable watery shroud, and often in remote regions of...
the seabed is young compared to the rest of the planet. Along the long, sinuous mid-ocean ridges where adjacent plates are slowly moving apart—known as divergent boundaries—magma rises from beneath Earth's crust. As the magma seeps through the gaps between plates, it rapidly cools, creating...

Ocean - Evaporation, Condensation, Precipitation: The huge volume of water contained in the oceans (and seas), 137 × 107 cubic km (about 33 × 107 cubic miles), has been produced during Earth’s geologic history. There is little information on the early
