Plate Tectonics

Front

What is created when two continental crusts push together at a convergent boundary?

Back

Mountains are created when two continental crusts push together at a convergent boundary.

Front

Where would the oldest rock be found in relation to tectonic plates?

Back

The oldest rock would be found farthest from the mid-ocean ridge, typically on the continental crust.

Front

What is a place where two tectonic plates slip past each other called?

Back

A transform boundary.

Front

What is the future prediction for Los Angeles and San Francisco in relation to the San Andreas transform boundary?

Back

Los Angeles and San Francisco will eventually be side by side somewhere between their current locations.

Front

Which type of crust is more dense, oceanic or continental?

Back

Oceanic crust is more dense than continental crust.

Front

What is the primary force driving plate tectonics?

Back

The primary force driving plate tectonics is convection currents in the mantle.

Front

What geological feature is commonly formed at divergent boundaries?

Back

Mid-ocean ridges are commonly formed at divergent boundaries.

Front

What is subduction, and where does it occur?

Back

Subduction is the process where one tectonic plate is forced under another, occurring at convergent boundaries.

Front

What type of boundary is characterized by plates moving away from each other?

Back

A divergent boundary.

Front

What is the Ring of Fire, and why is it significant?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, significant for its tectonic activity.
