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.
Seamount and Guyot. Mid-Oceanic Ridges  1.These are the most conspicuous features of the ocean basins.  2.The mid-ocean ridge is a continuous chain of mountains that runs from the central Arctic Ocean down through the Atlantic, through the Indian Ocean and northward through the eastern Pacific.  3.The mid-ocean ridge is approximately 1000 km wide and rises 1000 to 3000 m above the adjacent seafloor.  4.The mid-ocean ridge is 60,000 km long and covers 21% of Earth's surface.  5.
