CRCT Question

What is the plastic layer that the tectonic plates slide on?

  • asthenosphere

  • Lithosphere

  • Mantle

  • Crust

Task 1 earth s structure tier 1
Task #1-Earth’s Structure Tier 1

Great job everyone!

  • I only wrote down where you missed information

  • This was a homework grade 

Pt tier 2 options formative
PTTier 2 Options (FORMATIVE)

Option 1:

Design models to demonstrate the three main tectonic movements. Include a fact card for each movement that describes how to use the model, what causes the movement, and what happens because of that movement.

Option 2:

Create a script for a play that describes the three major types of boundaries. Be sure to describe the setting and characters. Your play should be typed or written in pen.



COMMUNICATED the following vocabulary (10 pts.):

  • Lithosphere

  • Asthenosphere

  • Convergent-mountain building, volcanoes, Mariana Trench, subduction

  • Divergent-mid ocean ridge

  • Transform-San Andres Fault, earthquakes

  • Convection currents

  • Plate Tectonics

  • Mantle

Each group will be assigned a hat!

  • Red Hat-Favorite part

  • White Hat-Facts

  • Black Hat-Questions you have about this. Why would this theory not work

  • Yellow hat-What are some things that you liked

  • Blue hat- What are some concepts you already knew about?

Plate Tectonics

Coffee Talk

The theory of plate motion
The Theory of Plate Motion

  • The lithosphere is broken into separate sections called plates. They “float” on the asthenosphere

  • Sea-floor spreading and continental drift into a single theory – The Theory of Plate Tectonics

  • Plate Tectonics – is the geological theory that states that pieces of Earth’s lithosphere are in constant, slow motion, driven by convection currents in the mantle.

  • The theory of plate tectonics explains the formation, movement, and subduction of Earth’s plates

Plate boundaries
Plate Boundaries

1. Transform Boundaries –

  • Crust is neither created nor destroyed

  • Place where two plates slip past each other, moving in opposite directions

Crct question

2. Divergent Boundaries

  • Place where two plates move apart

  • When develops on land, two of Earth’s plates pull apart. A deep valley called a rift valley forms along the divergent boundary

  • Example: Mid-Atlantic ridge

Crct question

3. Convergent Boundaries

  • Place where two plates come together

    Three types

    A. Convergingoceanicplate and oceanic plate collide one plate is subducted through a trench and volcano islands are formed

    B. Converging oceanic plate and continental plates – when continental plates and oceanic plate collide, the oceanic plate is subducted and volcanoes on land are formed

    C. Converging continental plates – where two continental plates collide, the crust buckles and mountain ranges form.

The continents slow dance
The Continents Slow Dance

  • The plates are moving at a very slow rate of about one to ten centimeters per year.

  • In areas plates are moving together and others are moving apart.
