Sentences with phrase «solid earth rotation»

Not exact matches

[Note that the earth's substantial crust is solid, and so it does not necessarily reflect the equilibrium shape for today's rate of rotation; in the geological past, the earth was rotating more rapidly.]

Regional variations arise because the Earth's gravity field is affected in multiple ways by the melt of ice, due to the direct effect of surface mass changes (the gravity field is determined by the distribution of mass), the consequent deformation of the Solid Earth (removing a load causes the Earth's surface to rebound, which in turn changes the distribution of the Earth's mass), the consequent redistribution of ocean water (the ocean surface is shaped by the gravity filed) and perturbations of the Earth's rotation axis (because of mass redistribution).

So especially the atmosphere (but also to some extent the ocean) will be affected by externally imposed changes in rotation rate via the global electrical circuit before the solid Earth is because they're several thousand times lighter.

The moon raises oceanic and solid Earth tides which by a secondary effect it exerts a gravitational drag on the Earth's rotation.

A whole bunch of heat engines using solid, liquid, and gaseous H2O as working fluid, heat reservoir, and heat sink all powered by the sun and earth's rotation setting the direction of rotation through Coriolis force.

Thus, on a wide range of time scales from several days to years, there is an agreement between the dynamics of the angular momentum in the atmosphere and solid earth, which come into view as small but important changes in the rotation of the planet.

Changes in its motion can change the rotation of solid Earth.
