Here is a list of 10 factors that can temporarily cause significant deviations in your blood pressure measurements. 1  Blood Pressure Cuff is too Small1,3,4 - It is extremely important to make sure the proper size blood pressure cuff is used on your upper arm when taking a measurement.
Mid-ocean ridges are geologically active, with new magma constantly emerging onto the ocean floor and into the crust at and near rifts along the ridge axes.The crystallized magma forms new crust of basalt (known as MORB for mid-ocean ridge basalt) and gabbro.ceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. There are two processes, ridge-push and slab pull, thought to be responsible for the spreading seen at mid-ocean ridges, and there is some uncertainty as to which is dominant.
A mid-ocean ridge is an underwater mountain system formed by plate tectonics. It consists of various mountains linked in chains, typically having a valley known as a rift running along its spine. This type of oceanic mountain ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading. The production of new seafloor results from mantle upwelling in response to plate spreading; this isentropic upwelling solid mantle material eventually exce
