Plate Tectonics and Boundaries

Front

What type of boundary creates new crust?

Back

Divergent Boundary

Front

Describe a Divergent Boundary.

Back

A boundary where two plates move away from each other, allowing magma to rise and create new crust.

Front

What aligns with Earth's magnetic poles in rocks?

Back

Iron bits inside the rock.

Front

Which fossils are considered the youngest due to the superposition of rock layers?

Back

Early horses.

Front

What happens at a Convergent Boundary?

Back

Plates move toward each other, forming mountains or causing subduction, leading to earthquakes and volcanoes.

Front

What is a Transform Boundary?

Back

A boundary where two plates slide past each other, causing earthquakes.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is subduction?

Back

The process where one tectonic plate moves under another, often leading to volcanic activity.

Front

What is the theory of plate tectonics?

Back

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

Front

What geological features are formed at Divergent Boundaries?

Back

Mid-ocean ridges and rift valleys.
