125Drilling mud — In geotechnical engineering, drilling mud, also known as spud mud (when beginning the drilling process), is a drilling fluid used to drill boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling… …
126Tachocline — The tachocline is the transition region of the Sun between the radiative interior and the differentially rotating outer convective zone. It is in the outer third of the sun (by radius). This causes the region to have a very large shear as the… …
127Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… …
128Reflection seismology — (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth s subsurface from reflected seismic waves. The method requires a controlled seismic source of energy,… …
