Study Hall: Sit in assigned seats, working on something quietly.

Warm up Without using your notes…. Draw a convection cell within the correct layer of the Earth’s interior using arrows to show how these currents move

Volunteers….

Homework Worksheet on Convection within the Earth Glue, staple, or tape into your notebook and add the entry into your table of contents I will be checking for this on Thursday during your notebook check!

Homework Worksheet…. We will review the homework from yesterday! Then we will continue with our notes….

Video on Alfred Wegener rao rao

Alfred Wegener ( ) write in notebook Credited with the “Theory of Plate Tectonics” Idea that all 7 continents were once one supercontinent: Pangaea (means "all lands"), He believed that over time the continents broke up and drifted apart

Evidence for Theory of Plate Tectonics write in notebook 1. Fit of the Continents 2. Fossil Evidence 3. Identical Rock and Soil Deposits

Explanation of the Evidence for Theory of Plate Tectonics 1. Fit of the Continents – Shape or outline of Eastern South America and Western Africa. – Appear to fit together like giant puzzle pieces

Evidence for Theory of Plate Tectonics 2. Fossil Evidence: – same fossilized plants and animals from the same time period were found in South America and Africa. – Also in Europe and North America, and Madagascar and India. – Many of these organisms could not have traveled across the vast oceans that currently exist.

Evidence for Theory of Plate Tectonics 3. Geological Rock and Soil Deposits – Identical rock types and geological features found in Appalachian Mountains (Eastern United States) and Scottish Highlands (Scotland)

Flip book In this activity, you are going to create a booklet which illustrates how the continents have moved over the last 200 million years ago Glue, staple, or tape into your notebook and add the entry into your table of contents I will be checking for this on Thursday during your notebook check!

Plate Tectonics Reading and Pangaea Puzzle In this activity, you will… 1.Read the article and write 5 facts you learned in your notebook 2.Complete the Pangaea Puzzle in your notebook by following the directions (we will go over these together as a class) Glue, staple, or tape into your notebook and add the entry into your table of contents I will be checking for this on Thursday during your notebook check!

Write in notebook Thin oceanic plates spread outward at areas known as mid-ocean rift (ridge) zones. Harry Hess: credited with “sea floor spreading” theory

Write in notebook Seismologists = Scientists who study how wave energy travels through the different layers of the Earth

Remember…. Parts of Waves: the number of waves that pass a given point in 1 second Frequency (speed of the wave) the height from the rest position to the bottom of the trough or from the rest position to the top of the crest Amplitude Distance from crest to crest or trough to trough Wavelength

Transverse waves…..

Write in notebook…. During an earthquake, energy is released into the Earth as: -Primary waves (compression waves) -Secondary waves (shear waves) -Surface waves

Write in notebook Primary (P) waves travel the fastest through both solid rock (granite mountains) and liquid regions (volcanic magma or water of the oceans) on the Earth Like sound waves (compression waves)

Write in notebook Secondary (S) waves travel the slowest and only travel through solid regions Like transverse waves

Write in notebook Surface waves = felt along the ground and Earth’s surface. Like waves or ripples of water that travel across a lake
