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.
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust. A classic example is the Mid-Atlantic Ridge where the Euras â¦ ian and African Plates are moving away from the North and South American Plates.7 people found this useful.he oldest rocks are located on continents, usually away from the ocean. The mid-ocean ridges are, in fact, home of some of the youngest rocks. The reason for this is wh â¦ at is called sea-floor spreading.
