The _______lithosphere
is divided into different tectonic plates. These plates move because of
______
in the asthenosphere. The North American Plate contains the continent of North America, as well as some of the surrounding Pacific and Atlantic Oceans.
Along its western border, two plates interact with the North American Plate. In the northern United States, the Juan de Fuca Plate ______
the North American Plate and subducts underneath. That’s because the Juan de Fuca Plate is _____
plate, which is denser than the ______
North American Plate. The subduction causes the plate to melt, becoming magma and forming volcanoes.
Near southern California and northern Mexico, the North American Plate and the Pacific Plate are both moving northwest, but the Pacific Plate is moving faster. This creates a _________
boundary as the plates slide past each other and create earthquakes.
Along its eastern border, the North American Plate is moving away from the Eurasian and African Plates (divergent boundary). This movement results in new crust rising to the surface along the boundary and the creation of underwater mountain ranges such as the Mid-Atlantic Ridge. That happens because convection currents within the asthenosphere are pulling the sea floor apart. This is also known as _________
, the mechanism that explains the driving force behind the moving plates and the theory of plate tectonics.
