At divergent boundaries ... Wannamaker and colleagues use electrical resistivity data to investigate a plate boundary in New Zealand where a subduction zone beneath the North Island is lengthening ...

Hand each student a plate boundary map and a slip of paper with ... Use Graphic 2 to discuss convergent, divergent, and transform boundaries. Explain why each of these boundaries has the ...

Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

This is called a constructive or divergent plate boundary. These are usually found under oceans. As the plate moves apart, magma rises to the surface and cools, forming shallow-sided volcanoes.

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

Here is a nice summary of sedimentation on divergent margins: be sure to look at the diagrams on the right side ... They are called passive because they are not near a plate boundary, and there is ...
