Open Ended Practice Radiation, conduction and convection (3 points) The uneven heating of the atmosphere helps to create the elements of our weather. How are each of the elements of weather influenced (effected) by the heating of the atmosphere? Be sure to discuss the following: Radiation, conduction and convection (3 points) Identify the elements of weather (6 points) Discuss how heat effects each element (6 points)
