The graph will show a plateau, where the temperature stops rising while boiling, even though the heat continues to be added. F. Explain that the heat is being absorbed by the steam and that it can come back when the steam or vapor turns back to water. Using a large globe, mark and X anywhere on the upper part of the Northern Hemisphere . Then make another X directly below the first one but much closer to the equator. The line will curve to the right and never hit the bottom X. B. Explain to students that this is what happens to the winds as they travel from one place to another in the northern hemisphere.
Winds always curve to the right relative to the place of origin.
Click here for a web sight on the formation of a hurricane. Ask the students to break into groups of 2 and read a hand out copy of this information . Pass out a data sheet giving the coordinates, date and time and wind speeds of a past hurricane. Have students chart the course of the hurricane on the map. From the information and the scale of miles , have the students calculate the speed the hurricane is moving in miles per hour.
