VOLCANOES & MORE :)

Quiz On Volcanoes & MORE! :) N :) E :) H :) A :)

QuestionAnswerR
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.
