Volcano Volcano TomChilders published on January 17, 2011 Stacked 1/20 Which of the following lava is produced by non-explosive eruptions? Hint: 1 choice Aa, Pahoehoe, Pillow Lava and Blocky Lava Aa, Pahoehoe, Volcanic Bombs and Blockly Lava Aa, Pahoehoe, Lapilli and Pillow Lava 2/20 Which answer best describes Blocky Lava? Hint: 1 choice Lava forms slowly like wax dripping from a candle. It is cool and stiff lava, that does not travel far from the erupting vent. Forms when lava erupts underwater. It pillows out of the vent. 3/20 Which type of pyroclastic material is known as "little stones"? Hint: 1 choice Lapilli Volcanic Bombs Volcanic Blocks 4/20 Which type of lava is known for its jagged surface? Hint: 1 choice Pahoehoe Aa Pillow Lava 5/20 Which of these are not pyroclastic materials Hint: 1 choice Volcanic Bombs Pahoehoe Lapilli 6/20 This type of lava is formed when gases and magma expand rapidly and the gas bubble explodes. Hint: 1 choice Volcanic Ash Volcanic Blocks Volcanic Bombs 7/20 Which type of pyroclastic material is formed by large blobs of magma which harden in the air and explode on impacting the ground? Hint: 1 choice Volcanic Ash Volcanic Bombs Volcanic Blocks 8/20 This type of volcano is also know as a stratovolcano. Hint: 1 choice Shield Composite Cinder Cone 9/20 This type of volcano consists entirely of pyroclastic material. Hint: 1 choice Composite Cinder Cone Shield 10/20 This volcano has sides that gently slope. Hint: 1 choice Composite Cinder Cone Shield 11/20 These volcanos are often found in clusters. Hint: 1 choice Cinder Cone Composite Shield 12/20 This type of volcano has a broad base and steep sides near the top. Hint: 1 choice Shield Composite Cinder Cone 13/20 This type of volcano forms from repeated non-explosive eruptions. Hint: 1 choice Composite Cinder Cone Shield 14/20 This type of volcano erodes very quickly because it is made entirely of pyroclastic material. Hint: 1 choice Cinder Cone Composite Shield 15/20 What relationship exists between the location of earthquakes and volcanoes? Hint: 1 choice Both produced lava eruptions. Neither are found on the edges of tectonic plates. Both are found on the edges of tectonic plates. 16/20 Which ocean has a ring of Volcanoes and earthquakes known as the "ring of fire"? Hint: 1 choice Atlantic Ocean Pacific Ocean India Ocean 17/20 Which ocean has a line of earthquakes and volcanoes down it's center? Hint: 1 choice Pacific Ocean Atlantic Ocean India Ocean 18/20 Also known as a volcanic crater. Hint: 1 choice Volcanic Bombs Vent Caldera 19/20 This type of volcano is made entirely from runny lava. Hint: 1 choice Composite Cinder Cone Shield 20/20 This type of volcano is created by explosive eruptions that are followed by lava outpourings. Hint: 1 choice Stratovolcano Both A and B Composite
