and tephra fallout hazard assessment at Tungurahua volcano Ecuador hazard maps with uncertainty quantification Alessandro Tadini Alvaro Aravena Andrea Bevilacqua Pablo . The Earth is Spinning…. Because Earth spins, winds and water appear to be deflected in a curved motion. This is called the Coriolis Effect. Which way do things. not connected to . Earth get deflected . Currents Currents Subject Review The following questions are based on information from the Tutorial on Currents ( http://oceanservice.noaa.gov/education/kits/cur - rent s /welcome.html ). 1. The _ Currents. Ocean water contains streamlike movements of water called . ocean currents.. Currents can travel extremely far.

Scientists place ocean currents into two major categories: surface currents and deep currents.. Surface . Currents. Ocean currents that occur at 328 feet deep or above. Hint, don’t forget to find the volume of the ice first!. ). Warm Up: Density of Ice. Does the density of ice you calculated make sense? Why or why not?. Warm Up: Density of Ice. Draw a dot diagram to compare the density of ice and water.. Created by Winds. Coriolis Effect- The shifting of ocean currents and surface winds from their expected paths caused by the rotation of the earth. Gulf Steam – ocean current in the northern Atlantic ocean, brings warm water from Africa to the Americas. An Explosive Impact. Flows and Fallout. Characteristics. Can flow like an avalanche. Can mix with water to form mudslides. Knock down trees and buildings. Dam up river valleys. Climate Changes. Volcanic ash and sulfuric gases reach atmosphere. Earth/Space. S.W.B.A.T..
