SCI LT REVIEW
1ST QUARTER, 10-DOCILITY
| Question | Answer |
|---|---|
| Earth's Layers, there are 2 types we can refer to | COMPOSITIONAL AND MECHANICAl. |
| consists of crust, mantle, and core. | COMPOSITIONAL |
| It is the outmost layer of the earth, the least dense of all the layers, and is divided into 2 types; continental crust and oceanic crust. | CRUST |
| is thicker than the other but it is less dense | Continental crust |
| is less thicker than Continental crust, yet it is denser than the other. | Oceanic crust |
| Thickest layer, and is denser than the crust. It also consists of semisolid, rocky, and very hot layer | MANTLE |
| The densest layer of the Earth, and is the innermost part of it. | CORE |
| Consists of Lithosphere, Asthenosphere, Mesosphere, Outer core, and Inner core. | MECHANICAL |
| a combination of the lower part of the crust and the uppermost part of the mantle, it also has what we call plates or tectonic plates. | LITHOSPHERE |
| Located below the mantle | ASTHENOSPHERE |
| Located within a portion of the mantle, right below the Asthenosphere. | MESOSPHERE |
| It is a liquid that is made of molten rocks. | OUTER CORE |
| unlike the outer core, is not liquid or molten. Due to the temperature, it makes the pressure intense which prevents melting | INNER CORE |
| are created by Earthquakes, Volcanic Eruptions, and other tectonic process. | SEISMIC WAVES |
| are instruments used to record the motion of the ground during an earthquake. | SEISMOGRAPH AND SEISMOMETER |
| TWO TYPES OF SEISMIC WAVE | BODY WAVES AND SURFACE WAVES |
| waves that travel through the inner layers | BODY WAVES |
| 2 TYPES OF BODY WAVES | P WAVES AND S WAVES |
| waves that travel through on the surface of the earth | SURFACE WAVES |
| Slippage along the fault or the plate boundary releases a tremendous amount of energy which causes vibration | EARTHQUAKE |
| formed along convergent boundaries wherein when two plates collide | VOLCANISM |
| formed between between the collision of continental-to continental convergence. | MOUNTAIN RANGES |
| derived from the word ‘Tekton’ which means carpenter or builder. The word tectonic used to describe the movement of plates | TECTONIC PLATES |
| the Lithosphere is divided into several plates that glide over the Earth's the rocky inner layer above the softcore | PLATE TECTONIC THEORY |
| 7 MAJOR PLATES | PACIFIC PLATE, NORTH-AMERICAN PLATE, EURASIAN PLATE, AFRICAN PLATE, ANTARCTIC PLATE, INDIO-AUSTRALIAN PLATE, AND SOUTH-AMERICAN PLATE |
| 8 MINOR PLATES | JUAN DE FUCA, COCOSPLATE, PHILIPPINE-SEA PLATE, INDIAN PLATE, NAZCA PLATE, CARRIBEAN PLATE, ARABIAN PLATE, AND SCOTIA PLATE |
| Earth has been affected by sudden, short-lived, violent events, that were sometimes worldwide in scope. Due to the great flood interpreted from the bible (really happened during the bronze age) | CATATROPHISM |
| is the assumption that the natural processes operating in the past are the same as those that can be observed operating in the present. | UNIFORMITARIANISM |
| Theorized that the Earth is contracting because it is cooling | JAMES DWIGHT DANA |
| Earth cooled after its formation. Heavier materials such as iron sank and formed the core, while lighter materials such as aluminum stayed up in the crust. | CONTRACTION THEORY |
| was a German Geophysicist and meteorologist | ALFRED WEGENER |
| Continents gradually drifted apart to where they are today | CONTINENTAL DRIFT THEORY |
| The idea was first presented in 1596, by the man who built the first atlas known as “Theatrum Orbis Terrarum” | ABRAHAM ORTELIUS |
| Wegener noticed the continents resemble jigsaw puzzle pieces | CONTINENTAL JIGSAW PUZZLE |
| a single landmass disintegrated, though he ascribed the cause to the Biblical Great flood | ANTONIO SNIDER-PELLEGRINI |
| Australian Geographer, Glossopteris could be found in 3 different continents | EDWARD SUESS |
| when a leaf, shell, skin, or foot leaves an imprint on soft earth. | IMPRESSION |
| a fossil that has been crushed or flattened but regains some organic material, although it has been Chemically altered | COMPRESSION |
| which does not have specific dates, allows one to determine if it is older than another artifact or fossil | RELATIVE DATING |
| provides more specific origin dates and time ranges, such as age range in years | ABSOLUTE DATING |
| is the study of climatic conditions of past geological ages | PALEOCLIMATOLOGY |
| the study of ancient magnetic field (magnetometer), Earth’s past magnetic field showed that the magnetic north pole seemingly wandered all over the globe. | PALEOMAGNETISM |
| was a geologist and navy submarine commander during World War II, Part of his mission had been to study the deepest part of the ocean floor | HARRY HAMMOND HESS |
| a device that bounces sound waves off underwater objects and then records the echoes of these sound waves. | SONAR |
| The process that continually adds new material to the ocean floor while pushing rocks away from the ridge | SEAFLOOR SPREADING |
| edges where two plates meet. | PLATE BOUNDARIES |
| are massive, rigid slabs of rock that form the Earth’s continents. They are the thicker and less dense type of tectonic plate. | CONTINENTAL PLATES |
| are large, rigid slabs of rock that form the ocean floor. They are thinner and denser than the other. | OCEANIC PLATES |
| 3 TYPES OF PLATE BOUNDARIES | CONVERGENT, DIVERGENT, AND TRANFORM |
| Plates move toward each other. Whereas tectonic plates collide or come together, they contribute to the formation of mountains, volcanic activity, and earthquakes | CONVERGENT |
| Plates move away from one another. This movement resulted in the creation of a new crust as magma rises from the mantle, it solidifies and forms a new oceanic crust | DIVERGENT |
| ; Plates slide past each other. These boundaries can cause earthquakes, as the plate grind against each other. | TRANSFORM |
