6.e.2.2 The Earth’s Plates

Do you think new mountains are being formed on Earth? How do you know? Warm up Do you think mountains are getting bigger on Earth today? Do you think new mountains are being formed on Earth? How do you know?

Volunteers? Yes, mountains are being slowly formed at plate boundaries across the Earth Our mission this week is to learn about tectonic plates and their movements which creates volcanoes, earthquakes and mountain building processes across the Earth’s surface

Alphabet booklet – match the words below with the correct definition and add to your booklet Thermal conductor the movement of heat energy from hot to cold Sclera the smallest unit of matter Pitch a material that easily allows heat energy to move Light refraction pure substances made of only 1 type of atom Heat transfer the tough, clear covering over the iris and pupil Elements the tough, white outer covering of the eye Cornea the highness or lowness of a sound Atom the bending of light as it travels between 2 different mediums

Can you name the 4 Layers of the Earth?

Review of the Earth’s layers http://www.youtube.com/watch?v=N9ncfAsmiSg http://www.youtube.com/watch?v=NAHY6965o08 As you watch the video, write down anything you hear that you do not understand

Song about the layers of the earth http://www.youtube.com/watch?v=Q9j1xGaxYzY Follow along with the words as the song plays

Question…. What are the two types of crust found on the Earth?

Remember….. Oceanic Crusts: (basalt) found under the oceans thinner but more dense Continental Crust: (granite) found under the continents thicker but less dense

Earth’s Layers Foldable Make sure you have glued, stapled, or taped this handout into your notebook

Write in Notebook The Earth’s crust is divided into 12 major tectonic plates These plates sit on the lithosphere Lithosphere = the crust and upper portion of the mantle

What is convection? Can we draw a picture of convection currents http://www.youtube.com/watch?v=WEDUtS0IMws

Convection currents in the earth http://www.youtube.com/watch?v=jkKlGXG4lG8

Write in notebook The Earth’s plates move about 2 inches per year (5 centimeters) Convective currents in the mantle = plates move As they move, the plates: Press against one another (convergent boundary) Pull apart from one another (divergent boundary) Scrape against one another (transform boundary)

Draw these Plate boundaries……

Write in notebook At these plate boundaries we get : Earthquakes Volcanic Eruptions Mountain Building

Go back to your drawings….add these notes beside each drawing

Write in notebook BESIDE CONVERGENT BOUNDARY New mountain ranges form: 2 continental plates press against one another 1oceanic plate and 1continental plate press against one another

Write in notebook BESIDE DIVERGENT BOUNDARY Where plates spread apart: New crust is formed here Volcanoes occur here! Called mid-ocean rift zones

Write in notebook BESIDE TRANSFORM BOUNDARY Plates scrape past one another Earthquakes occur here San Andreas fault in California is an example

Yellow Textbook B82-96 Brochure activity You will be creating a brochure detailing plate boundaries You will use the notes you took in class to create your brochure as well as our Yellow Textbook B82-96 We will go over the requirements and rubric now
