Question | AnswerR |
---|---|
Volcano Type : # 1 : Shield Volcano | Is the largest type , where thin layers of lava pour out and cover an another layer. When facing down it looks like a warrior shield.It is gently sloped. |
Volcano Type : # 2 : Cinder cone volcano | It is the smallest type of volcano and created by explosive eruptions. It has a very steep slope and the lava is thick so it produces ash and cinder that pile around the bottom of the volcano |
Volcano Type : # 3 : Composite Volcanoes | It holds lava that flows with ash and cinder. It is very tall and cone shaped with the lava alternate , ash. |
Lava Flow Type # 1 : Pahoehoe | Pahoehoe is a very fast moving lava that is much hotter than Aa. It also has very little silica. |
Lava Flow Type # 2 : Aa | Aa is a very slow moving type of moving lava. It is also much cooler than Pahoehoe. It also has a lot of silica and more than Pahoehoe. |
Lava Flow Type # 3 : Pyroclastic | Pyroclastic flow is the most dangerous type of flow. It occurs during explosive eruptions when the magma gets stuck in a volcanoes pipe and the pressure build up till it explodes. |
How to remember the parts of a volcano? | Look at the Textbook and look at the Review Sheet to MEMORIZE the diagram |
What is a Hot Spot? | An area where magma burns through the crust like a blow torch. |
What is a Geyser? | A jet of very hot water that shoots up out of the ground. |
What is an EXTINCT volcano? | A volcano that will never erupt againg |
What is a Caldera? | A large crater that is produced when a volcano empties its magma chamber |
What is the Ring of Fire? | A chain of volcanoes around the Pacific Plate |
What is a DORMANT volcano? | A volcano that is "sleeping" |
What is an EXPLOSIVE eruption? | Type of eruption that produce pyroclastic flows. |
What is Silica? | Silicone + Oxygen |
What is a Hot Spring? | Pool of water that is heated up by magma |
What is an ACTIVE volcano | A volcano that is currently erupting. |
What is a QUIET Eruption | Eruption that cause two types of lava |
What is a Volcanic Neck? | Forms when magma in a volcano's pipe cool off. |
What is a Batholith? | Forms when a volcano's magma chamber cools off. |
Divergent Boundries | Move outward in opposite directions. ( TWO PLATES ) |
Convergent Boundries | Two plates collide causing one to dive agains the other |
Transform Boundries | Two plates slide against each other inward in opposite directions. |
Anticlines | Piece of land that arches and , or bends upwards. |
Syncline | It bends down words. |
Plateau | A peice of land elevated above sea level. |
Folding | The bending of rock upwards or downwards , causing permanent deformation |
Difference between Tidal waves and Tsunamis. | Tsunamis are cause by earthquakes while tidal waves are cause by the moons gravitational pull. |
Mercelli Scale - Richter Scale - Moment Magnitude Scale - | Only finds the intensity of small earthquakes Measures the magnitude for nearby or small earthquakes This is good for everything in all earthquakes. |
SAFETY PRECAUTIONS FOR EARTHQUAKES | - Drop , Cover Hold - Get under a table - Stay away from glass AND windows - Stay away from all falling building ? structures - If there is a tsunami stay above sea level |
Focus | Center of the earthquake AND where a earthquake starts |
Epicenter | The point on the SURFACE directly above the focus. |
Stress | A force that acts on rock to change it's shape or volume |
Deformation | The change of stress or volume in the earths crust |
P-Waves ( Primary Waves ) S-Waves ( Secondary Waves ) Secondary Waves ~~~~~~~~~~~~~~~~~~ | Compress and expand the ground , come first Vibrate side to side , up and down , and also shake structures violently MOve very slowly but are the most destructive and produces severe ground movement. |
