| Used by scientists as basis for dividing lithosphere into several plates | VOLCANISM, SEISMIC ACTIVITY & MOUNTAIN FORMATION |
| Geologic events and features such as earthquakes, active volcanoes, and major mountain ranges are distributed ______ | Near or along plate boundaries. |
| The sudden shaking of the ground that may result in destruction of infrastructure and lives. | Earthquake |
| Is the point on the surface of the earth that lies directly above the origin of the earthquake. | Epicenter |
| 2 types of Seismic Waves | Body waves and Surface waves |
| 2 types of Body waves | P wave and S wave |
| 2 types of Surface wave | Rayleigh wave and Love wave |
| Is used to record the motion of the ground. | Seismograph |
| Scientists use the ______________________________ to get the distance of the epicenter from the seismic station. | Difference in the arrival time of P-wave and S-wave |
| Three distances from three different seismic stations are needed to determine the exact location of the epicenter using a method known as ____________. | Triangulation method. |
| Is any physical feature of the earth’s surface that is formed by a geologic process. | Geologic Features |
| Distribution of earthquake epicenters | Scattered everywhere |
| Distribution of active volcanoes. | Along the edges of the plates. |
| Distribution of MOUNTAIN BELTS (MOUNTAIN RANGE) | Along the edges of the plates |
| Is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. | Radioactive Dating Technique |
| A theory which suggests that Earth’s crust is made of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes, and other geologic features. | Plate Tectonics Theory |
| Is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. | A MOUNTAIN SYSTEM OR MOUNTAIN BELT |
| Refers to mountains formed in the same age and with the same process arranged in narrow and long belts | Mountain Range |
| Folded mountain belts sometimes form at _________ boundaries because the rock is compressed and forced upward. | Convergent plate |
| What makes up the lithosphere? | Crust and upper mantle |
| Where is the location of active volcanoes, earthquake epicenters, and major mountain belts? | Along the edges of the plates |
| How earthquake epicenters, active volcanoes, and major mountain belts are distributed? | The distribution of earthquake epicenters is different from active volcanoes, and major mountain belts |
| What is needed to determine the epicenter of an earthquake? | The distance of the epicenter from three different seismic stations |
| What is needed to determine the distance of the epicenter from a seismic station? | I believe ito ang sagot (The difference in the arrival time of P-wave and S-wave) pero ang sabi ni maam ay ito (The difference in the arrival time of P-wave and S-wave from three different seismic stations) and I, Thank you. |
