Plate Boundaries and Magnetic Reversal 10.25.23

Front

What type of plate boundary occurs when plates move towards one another?

Back

Convergent boundary.

Front

What type of plate boundary occurs when plates slide past one another?

Back

Transform boundary.

Front

What is the geological feature most commonly associated with transform boundaries?

Back

Fault lines and earthquakes.

Front

Where would the oldest rocks typically be found in relation to plate boundaries?

Back

At oceanic ridges, specifically on the ocean floor, the oldest rocks are found furthest from the ridge.

Front

Which two continents fit together most noticeably due to plate tectonics?

Back

South America and Africa.

Front

What is the primary process that occurs at divergent boundaries?

Back

The creation of new oceanic crust as tectonic plates move apart.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is the significance of magnetic reversal in relation to plate tectonics?

Back

Magnetic reversal provides evidence for seafloor spreading and the movement of tectonic plates.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another and is forced into the mantle.

Front

What type of boundary is characterized by the formation of rift valleys?

Back

Divergent boundary.
