What are the similarities and differences of convergent and divergent boundaries?

The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.

What characterizes the different types of plate boundaries?

Tectonic Plates and Plate Boundaries

• Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
• Divergent boundaries – where two plates are moving apart.
• Transform boundaries – where plates slide passed each other.

How will you describe the three types of plate boundaries?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.

What is the difference between convergent collision and convergent subduction?

These convection currents cause the tectonic plates to move several centime- ters per year relative to each other. If two tectonic plates collide more or less head-on they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, which is known as subduction.

What are examples of convergent boundaries?

An example of an oceanic/oceanic convergent boundary is that between the Pacific and Mariana plates, which includes the Mariana Islands arc and a subduction zone encompassing the Mariana Trench , the deepest part of the World Ocean.

What are the two types of divergent boundaries?

Divergent boundaries are where two of those plates are moving away from each other. When this happens, magma rushes up to fill the gap, creating brand new crust. Plates can be separated into two types: oceanic and continental.

Where are the most divergent boundaries found?

Most modern divergent plate boundaries are found in the mid-ocean ridges. When rocks are hotter such that they are higher and less dense, they cause ridges in the ocean.

What is a real life example of a convergent boundary?

The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. Here the Nazca Plate is subducting beneath the South American plate .
