SCIENCE 6 LET US OBSERVE! Questions: 1. What are the different parts of an egg? 2. What entity reminds you of an egg? 3. Does an egg look like the Earth? 4. What do the egg shells represent? 5. How about the egg whites? The egg yolks? Forces That Affect Changes On Earth’s Surface Learning Objectives: demonstrate understanding on the forces that change the Earth’s surface; describe the changes on the Earth’s surface as a result of earthquakes; and enumerate ways on what to do before, during, and after the earthquake. Earth’s Interior Earth’s Interior The Crust the outermost and the thinnest layer of the Earth it is where living things live it is divided into: continental crust and oceanic crust The Mantle the second layer of the earth believed to be made of thick liquid containing silicon, oxygen, iron, and magnesium The Mantle divided into three layers: the uppermost layer, the asthenosphere, and the lowermost layer The Core Outer Core is made of hot liquid molten materials that contain iron and nickel The Core Inner Core made of iron and nickel greater pressure in the inner core pushes the particles of iron and nickel to tightly together that the elements remain solid The Core Inner Core the presence of solid iron in the inner core may explain the existence of Earth’s magnetic field Complete the concept map below. Crust: 1. outer and the ______________ layer 2. consist of _____________________ and oceanic crust Mantle: 3. This is the layer between the crust and core. It is divided into three layers- the uppermost layer, the _____________, and the lower mantle Core: 4. The innermost layer consists of two layers and made up of __________ and ___________. 5. The presence of solid iron in the inner core explains the __________________. Forces That Affect Changes On Earth’s Surface Plate Boundaries Earth is not a solid and continuous shell, the crust is divided into two parts: The continental crust holds the different continents. The oceanic crust holds different bodies of water. The present continents lie on a tectonic plate Tectonic plate is a massive, irregularly shaped slab of solid rock. These tectonic plates are moving in different direction. Plate Boundaries and Movements Plate boundaries are areas where the plates meet. Plates move or drift slowly. Plates interact in several ways either they collide, separate, or slide. This movement causes geological events like earthquakes, volcanic eruptions, and the formation of oceans and continents. Earthquake: Causes and Hazardous Effects Earthquakes are vibrations in the ground that are caused by the sudden release of energy. This energy cause vibrations that transfer in a form of wave called seismic wave. Tectonic Earthquake two tectonic plates move suddenly against each other Volcanic Earthquake occurs in areas that are associated with volcanic activities Seismology is the field in science that studies the occurrences of earthquakes. Seismologist are group of scientists that deals with the study of earthquakes. Measuring an Earthquake A seismograph measures and records the activities of an earthquake. Measuring an Earthquake Richter Scale measures the strength of magnitude of an earthquake. Effects of an Earthquake Destruction of properties and loss of lives. Effects of an Earthquake Landslide and avalanche Effects of an Earthquake Tsunami Earthquake in the Philippines The Philippines is part of the Circum-Pacific Belt or Pacific Ring of Fire. A region where many volcanic eruptions and earthquake oc curs. https://www.youtube.com/watch?v=m7XZzg7Tzio LET US APPLY! As a group, get a one-whole sheet intermediate paper and divide it vertically to three equal parts. LET US APPLY! List down at least five things to do before, during, and after an earthquake occurs. LET US MAKE MEANING! Philippines is located near the Pacific ring of fire, which makes it highly vulnerable for seismic activities or earthquakes. Due to its geographical location, Philippines also is visited by typhoons. With an average of twenty typhoons every year. LET US MAKE MEANING! ○ What is the importance of keeping calm when a natural disaster occurs? ○ What value should we embody when helping other people in times of natural calamities? ○ How do we show these values to those who are affected by natural calamities? Generalization: Share a phrase about what you have learned from the discussion.
