8th Science Plate Tectonics

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where two tectonic plates are moving apart.

Front

What type of plate boundary is associated with rift valleys?

Back

Divergent boundary.

Front

What is the primary force driving tectonic plate movement?

Back

Convection currents in the Earth's mantle.

Front

What is the San Andreas Fault?

Back

The San Andreas Fault is a transform fault located in California, where two tectonic plates slide past each other.

Front

Which of the following is NOT evidence for plate tectonics: Fossils, Continental fit, Glaciers, or Sand Erosion?

Back

Sand Erosion.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains or deep ocean trenches.

Front

What happens at a transform boundary?

Back

Tectonic plates slide past each other, causing earthquakes.

Front

What is the theory of plate tectonics?

Back

The theory that the Earth's outer shell is divided into several plates that glide over the mantle.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates.

Front

What type of boundary creates new oceanic crust?

Back

Divergent boundary.
