EARTH MATERIALS AND PROCESSES LESSON 6  OBJECTIVES Categorize the geological processes affecting rocks Discuss both endogenic and exogenic processes Presentation title 2 20XX  Introduction Earth processes refer to the various natural and physical phenomena that occur on our planet, shaping its surface, atmosphere, and interior. Earth’s Processes: Geological Processes - Atmospheric Processes Hydrologic Processes Biogeochemical Processes Human-Induced Processes 3 EARTH’S GENERAL PROCESSES It is also known as internal processes. Any geological forces and phenomena that originate ENDOGENIC from within the Earth’s interior. These processes are driven by the heat generated PROCESSES within the Earth and the movement of materials beneath the Earth’s surface. It is also known as external processes or exogenic geomorphic processes Any environmental forces that shape the Earth’s EXOGENIC surface by breaking down and wearing away PROCESSES landforms. These processes are primarily driven by external factors. 4 Presentation title 20XX EARTH’S GENERAL PROCESSES ENDOGENIC PROCESSES EXOGENIC PROCESSES TECTONIC PLATE MOVEMENT WEATHERING VOLCANISM EROSION MOUNTAIN BUILDING TRANSPORTATION EARTHQUAKES DEPOSITION MAGMA INTRUSION 5 Presentation title 20XX  ENDOGENIC PROCESSES EXOGENIC PROCESSES OBJECTIVES: ✔TO EXPLAIN CONTINENTAL DRIFT THEORY ✔TO IDENTIFY THE DIFFERENT EVIDENCES SUPPORTING CONTINENTAL DRIFT THEORY CONTINENTAL DRIFT THEORY 7 Presentation title 20XX  ALFRED WEGENER German meteorologist and geophysicist who proposed the Continental Drift Theory. Continental Drift Theory CONTINENTAL DRIFT DESCRIBES ONE OF THE EARLIEST WAYS GEOLOGISTS THOUGHT CONTINENTS MOVED OVER TIME.  This map displays an early "supercontinent" Rodinia, which eventually moved to form the continents we know today. Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. 9 Presentation title 20XX  EVIDENCE OF CONTINENTAL DRIFT THEORY There are pieces of evidence that support Wegener's theory. first evidence Fit of the Continents  FIT OF THE CONTINENTS If you look at the map, it is looks like a big jigsaw puzzle wherein you can rearrange and merge the pieces as if they belong to only one big piece The edge of one continent matches the edge of another, such as that of South America and Africa, and Eurasia and North America.  SOUTH AFRICA AMERICA EURASIA NORTH AMERICA  There are pieces of evidence that support Wegener's theory. Second Evidence Fossil Remains  FOSSIL preserved remains of organisms (plant or animals) from the past. GLOSSOPTERIS MESOSAURUS LYSTROSAURUS There are pieces of evidence that support Wegener's theory. Third Evidence Similar Rock Formations  Similar rock types, mineral compositions, and geological formations are found on continents that are now far apart. For example, rocks in the Appalachian Mountains of North America match those in the Caledonian Mountains of Europe, even though these regions are separated by the Atlantic Ocean. There are pieces of evidence that support Wegener's theory. fourth evidence Presence of Coals  COAL formed from organic compounds such as dead plants and animals. Looking at the current location of Antarctica, one can say that it could sustain life. However, coal deposits were found in this region, which means that Antarctica was once part of a region that sustained life, and it was able to experience a tropical climate.
