CONTINENTAL DRIFT THEORY EVIDENCES ppt

•Download as PPT, PDF•
•

The document discusses evidence that supports the continental drift theory proposed by Alfred Wegener. It describes an activity where students reconstruct the supercontinent Pangaea by fitting together continent landmass cutouts. The activity aims to showcase two key evidence: 1) the apparent fit of continents and 2) fossil correlations found across different continents. It also discusses two additional evidence put forth by Wegener: 3) past climate data like glacial striations found in present-day equatorial regions, and 4) correlations between mountain ranges and rock formations between separated continents.

Objectives: •Recreate Pangaea •Explain how the first two(2) evidences presented supported the Continental Drift Theory
What is PANGAEA?

“Drifted Supercontinent” Objective: Reconstruct and describe Pangaea Procedure: 1.) Refer to the displayed present world map. 2.) Each cut-out continents has already label in it. 3.)Paste the cut-out continents in a long bondpaper in their respective positions. 4.) Continents must be closer to each other to recreate a Pangaea. 5.) Questions displayed on the board must be discussed within the group. 6.)Write your group number and members at the back of your paper.
RUBRICS FOR SCORING OF THE OUTPUT • EXACTITUDE OF DATA - 5 POINTS 5 pts -Continents are in their correct position are connected 4 - Continents are in their correct position but are not connected 3 - Continents are connected but not in correct position • NEATNESS - 2 pts. 2 - Cut-outs are not crumpled • TEAMWORK - 3 pts. 3 - maximum participation of members and tasks are divided 2 – half of the members have no participation 1 – only the leader and secretary are working • TIMELINESS - 3 pts 3 - the first to finish the task 2 - finishes on time 1 - finishes late COMPREHENSION - 2 pts • 2 POINTS FOR THE ASSIGNED QUESTION TOTAL POINTS = 15pts
1.Which continents do you think were neighbors before? 2. What does the presence of Mesosaurus, Cynognathus and Lystrosaurus tells about the initial location and positioning of South America and Africa? 3.If Glossopteris were found in Antarctica, what was the climate of the continent before? 4. What are the two evidences that supported the Continental Drift Theory based on your activity?
The World
ALFRED WEGENER THEORY OF CONTINENTAL DRIFT Found evidence for PANGAEA and proposed the theory of continental drift.
Continental Drift • Theory that continents were once part of a single landmass that broke apart and have moved to their present locations. • can drift apart from one another and have done so in the past
Pangaea Pangaea is the name given to the single landmass that was present 250 million years ago

WEGENER’S EVIDENCE 1. APPARENT FIT OF THE CONTINENTS Continents “fit together” like puzzle pieces Q1.Which continents do you think were neighbors before?
WEGENER’S EVIDENCE 2. FOSSIL CORELATION •fossils are remains of living things that lived long ago. •similar fossils have been discovered in matching coastlines on different continents.
WEGENER’S EVIDENCE Q.2What does the presence of Mesosaurus, Cynognathus and Lystrosaurus tells about the initial location and positioning of South America and Africa? Q 3.If Glossopteris were found in Antarctica, what was the climate of the continent before?

What the world would look like million years from now if the continents continue to move?

•Where do you think was the Philippines located during the time that Pangaea existed? •Where is the Philippines located at the present time? •Where do you think Philippines will be located 300 million years from now?
•If you live in Wegener’s time, are the two evidences enough for you to believe him?Why?
• Study in advance the 3rd and 4th evidence presented by Alfred Wegener in his Continental Drift Theory. 3. PAST CLIMATE DATA 4. ROCK AND MOUNTAIN CORRELATION
Continuation: Day 2
Objectives: • Explain how • rock and mountain correlation and •.paleoclimate data supported the Continental Drift Theory of Alfred Wegener
WEGENER’S EVIDENCE • Mountains • Some mountain ranges on different continents seem to match. • Ex: ranges in Canada match Norway and Sweden • Northeastern parts of US and Canada & Northern Europe ranges • Ex: Appalachian Mtn. match UK mtn

PALEOCLIMATE DATA • Climatic evidence such as glaciers in areas that are now close to the Equator
a. Glacial Striations -when glaciers scratch the surfaces of rocks and other things that they float above of. -found in middle of South America and Central Africa that are now close to the equators
b. Bituminous Coal -a type of fossil fuel which is made of compressed plant remains -Discovered in South America, Africa,Indian subcontinent, Southeast Asia and even in Antarctica
