Get your journal; be ready at the bell

Warm up 1.) Guess – How old is the Earth? 2.) Name a way that you think the Earth has changed over time. 3.) Some people think that the shape of some coast lines look very similar. Like they almost could fit together. Where on this map do you see that possibility?

JQ6 w1 On 1/22 (B) and 1/23 (W), what was the answer to warm up question #4? On 1/22 (B) and 1/23 (W), what did we write for slide 3? On 2/5 (B) and 2/6 (W), what was the answer to warm up question #4? On 2/7 (B) and 2/8 (W), what was the answer to warm up questions 2-4? (write the words that went in the blanks) On 2/7 and 2/8 (W), what did we write for slide 7?  ( just the words in the blanks)

Get out two sheets of paper to hand in. Today is the last day of MP3 Get out two sheets of paper to hand in. Today is the last day of MP3. Finish strong!

Warm up 1.) Get out your puzzle pieces and rearrange them back to how you think they go. 2.) What clues did you use to put the puzzle together? I used the shapes and colors to try to match where they best fit together. 3.) What was the point of the puzzle activity? To show how the continents could have fit together at one point. 4.) Today is the last day of the marking period and your last chance to improve your grade. What can you do today to improve?

Get your journal and get out your HW if you have it (Lesson 3 section 1). Also two sheets of paper.

Warm up 1.) We did a puzzle activity. What was the point of doing the puzzle activity? To see what the world used to look like 2.) We colored in sections of our puzzle. What did the different colors represent? They represented where different fossils were found 3.) Today is the first day of the fourth marking period. What does that mean for your grade? It means your grade resets and you start fresh

Are similar coastlines in some areas enough proof?

Continental Drift Theory that continents were once connected, and have since moved to current positions Supercontinent called Pangeae Alfred Wegener’s idea

Fossil Evidence

Geologic (rock) Evidence

Climate Evidence

Summary of Evidence for C.D. 1.) Coastlines look similar 2.) Different fossils found in different parts of the world. 3.) Mountain ranges extending across continents 4.) Climate evidence of glacial valleys where it is hot.

While the evidence is intriguing (sounds like it could be true) no one believed until many years later after another discovery.

JQ 8 1.) On 3/12 (W) and 3/13 (B), what was the answer to warm up question 1? 2.) On 3/18 (W) and 3/19 (B), what was the answer to warm up questions 3? 3.) On 3/25 (W) and 3/26 (B), what was the answer to warm up #3? 4.) On 4/1 (W) and 4/2 (B), what was the answer to warm up #3? 5.) On 4/1 (W) and 4/2 (B), what was the last thing wrote in our notes?

Get your journal and take your seat Get your journal and take your seat. Get out a sheet of paper to hand in and any homework you may have

Warm up 1.) What is a theory? 2.) Who tried to prove the idea of continental drift? 3.) Describe one of the types of evidence he found in some detail. How did it help prove his theory? 4.) Why did no one believe the theory to be true at the time? 5.) Today you’re getting a grade sheet. What do you predict your grade will be? Why?

Grade sheet analysis 1.) What was your overall grade? 2.) What is your overall % in: Classwork Homework Assessments 3.) How many “unusable scores” did you have? 4.) What did you get on your project? 5.) What is your goal for the last marking period? How will you attain your goal? 6.) What are the four pieces of evidence Wegener came up with? (look in notes)

Get your journal and get out your signed grade sheet if you have it.

Warm up 1.) What did Alfred Wegener’s theory try to explain? 2.) Name one of the four main pieces of evidence Wegener found. 3.) Look at this picture. The grey Are landmasses. The ocean floor Is color coded. What could the Colors represent? 4.) What does the inside of the Earth look like? What’s there?

Review of HW questions from text The structure of Earth’s interior is determined by measuring ___________.

Sea Floor Spreading - ocean floor is spreading apart at certain areas called the mid – ocean ridge

Theory of Plate Tectonics – the earth’s crust is divided into plates that are slowly moving

Plate Boundaries (3 kinds) The edges of the plates are plate boundaries. 3 things can happen Divergent – 2 plates moving away from each other move apart; more lava replaces

Convergent – collision of two plates - 2 types

- subduction – dense ocean crust goes under less dense cont. crust

- continent vs. continent – neither crust less dense; crumpled into mtns.

Transform – 2 plates grinding past each other (earthquakes common) - Ex. – San Andreas Fault
