He had no-body to go with

QUIZ ON MONDAY

Heads Up Buttercups

Great job everyone!

I only wrote down where you missed information

This was a homework grade

Task #1-Earth’s Structure Tier 1

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.

DUE WEDNESDAY

Yellow hat-What are some things that you liked

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

Plate TectonicsCoffee Talk

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

The Theory of Plate Motion

10 Major Plates

1. Transform Boundaries – Crust is neither created nor destroyedPlace where two plates slip past each

other, moving in opposite directions

Plate Boundaries

2. Divergent Boundaries Place where two plates move apartWhen 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

3. Convergent BoundariesPlace where two plates come together

Three typesA. Converging oceanic plate and oceanic plate collide one plate is subducted through a trench and volcano islands are formedB. Converging oceanic plate and continental plates – when continental plates and oceanic plate collide, the oceanic plate is subducted and volcanoes on land are formedC. Converging continental plates – where two continental plates collide, the crust buckles and mountain ranges form.

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.
