Volcanic activity in the Hawaiian Islands is the result of Chain in North America is caused by a) subduction zone processes; intra-plate volcanics b) sea floor spreading: a suture zone c) continental riting; subduction zone processes d) Hot Spot volcanics; subduction zone processes 4. High viscosity magma is associated with : low viscosity magma is associated with Composite Volcanoes; Shield Volcanoes Shield Volcanoes; Composite Volcanoes Hot spots; intra-plate volcanics Subduction zones; plate convergence a) b) c) d) 5. We organize cloud types based on which of the following categories? a) Shape; altitude; latitude b) Altitude; shape; rain-producing c) Shape; altitude; density d) Size, shape; altitude 6. According to the Moment Magnitude Scale, the size of an earthquake is determined by a) The number of structures destroyed b) How long the shaking lasts and how far away shaking is felt Size of the fault plane and distance of slip c) d) The type of fault and the depth of the rupture Era and the Period. 7. In the geologic time scale, we are currently in the a) Pleistocene; Quaternary b) Quaternary; Holocene c) Cenozoic; Quaternary d) Cenozoic; PleistoceneExplanation / Answer
1. Compared to continental crust, ocean crust is- d) Denser, thinner. Because of this reason oceanic plates always subduct.
2. A phase change of water from one stage to another is accompanied by the storage or release of (d) heat energy.
3. Volcanic activity in the Hawaiian Island is the result of Hotspot volcanics ; Volin Ncanic activity inthe Cascade chain North America is caused by subduction zone processes.
4. High viscosity magma is associated with composite volcanoes ; low viscosity magma is associated with shield volcanoes.
Composite volcanoes are alternate layers of lava flow and pyroclastics. On the other hand,shield volcanoes are composed of basaltic lavas, so they are less viscous and form low-height cone compared to its diameter.
5. We organize cloud types based on c) shape; altitude; density.
6. According to the Moment Magnitude Scale, the size of an earthquake is determined by b) how long the shaking lasts and how far away shaking is felt. Because this scale measures the total energy released by an earthquake.
7.In the Geological time scale, we are currently in the Cenozoic Era and Quaternary Period.
