Plate Boundaries

What are Plate Boundaries?

How is Earth's crust divided?

Earth's Layers

• Earth is made of four layers.

• We live on the crust, made of cool rocks and oceans.

• Next, we have the mantle made of hot liquid rock.

• Then we have the inner and outer core. They are extremely hot and made of metal.

• Scientists made inferences about the inner layers. We cannot really dig through the Earth because the inner layers are so hot.

Open Ended

"Scientists have learned about the inner layers by _____ because _____."

Earth's Plates

• The crust is made of solid rock called Plates. There are 12 main plates.

• Remember that the plates are solid, but they are floating on the mantle, which is liquid. ​

• So, the plates ​move due to changes that happen in the mantle below.

• The movement of the plates is called Plate Tectonics.​

Multiple Choice

Earth's crust is ___.

• One smooth shell

• Cracked into 12 plates

Multiple Select

Which two facts help to explain why the plates move?

(Pick 2!)

• The plates in the crust are liquid.

• The plates in the crust are solid.

• The mantle below is solid.

• The mantle below is liquid.

Multiple Choice

The movement of the plates is caused by ___.

• Magnets

• Asteroids

• Changes in the mantle

Multiple Choice

The movement of Plates is called "Plate ___."

• Drift

• Tectonics

• Transfer

​Plate Boundaries

• A boundary divides two things.

• Most changes in the geosphere happen at boundaries between two plates.

• To make the geosphere easier to study, scientists classify the boundaries into three types:

  • Divergent

  • Convergent

  • Transform

  ​

Multiple Choice

A line dividing two things is called a ____.

• Plate

• Geosphere

• Boundary

Multiple Choice

A fence that divides two yards is an example of a ____.

• Plate

• Geosphere

• Boundary

Multiple Select

Which 2 are examples of boundaries?

(Pick 2!)

• A wall dividing two classrooms

• A hallway that connects all the rooms

• A mountain range dividing two countries

• A carpet that covers the whole floor

Multiple Choice

Scientists study Plate Boundaries because ____.

• The government forces them to.

• Most changes in the geosphere happen at plate boundaries.

• The plate boundaries never change so they are easy to study.

Multiple Choice

To make the geosphere easier to study, scientists classify plate boundaries into:

• Solid

  Liquid

  Gas

• Producer

  Consumer

  Decomposer

• Divergent

  Convergent

  Transform

​Plate Boundaries

• "​Verge" means boundary.

• A divergent boundary is a place where two plates spread apart.​

• A convergent boundary is a place where two plates come together.

• A transform boundary is a place where plates ru​b against each other.
