WebDivergent Plate Boundaries. As with convergent boundaries, divergent plate margins can occur within the oceanic or continental portions of plates. Divergence between oceanic plates produces ocean-spreading ridges (mid-ocean ridges), where magma from the mantle rises to create new oceanic crust (Fig. 6). WebPlate Tectonics is a theory developed in the late 1960s, to explain how the outer layers of the Earth move and deform. The theory has caused a revolution in the way we think about the Earth.

The … WebIceland lies on the Mid Atlantic Ridge, a constructive plate boundary, where the North American and Eurasian plates are moving away from each other. As the plates pull apart, molten rock (magma) rises up and erupts as lava, creating new ocean crust. The island is covered with more than 100 volcanoes. Some are extinct, but over 30 are still active.

WebAn example of such a margin is the Mid Atlantic Ridge. Conservative (transform) plate margin - these involve two plates sliding past one another, either in opposite directions, or the same direction at different rates. Friction and tension between the plates build until it is released, resulting in a jolt which is an earthquake. WebA really good example of this is the mid Atlantic Ridge, where the Eurasian plate moves away from the North American plate at a rate of around 4cm per year. Iceland owes its existence to this ridge. Indeed, the Atlantic Ocean did not exist approximately 150million years ago. The ridge is not a continuous linear line in the ocean.
