Across 4. an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. 6. Forms on cold glasses of lemonade 7. The geological process in which sediments, soil and rocks are added to a landform or land mass. 8. You feel this in your ear drums when you go up in a plain. 10. This provide the non-gaseous surface necessary for water vapor to condense into cloud droplets. 12. Measures humidity 13. a wind blowing steadily towards the equator from the northeast in the northern hemisphere or the southeast in the southern hemisphere, especially at sea. 15. a body of air with horizontally uniform temperature, humidity, and pressure. 16. Occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. 19. How water goes into the sky 21. The transition of a substance directly from the solid to the gas phase 22. is the boundary between the polar cell and the Ferrel cell around the 60° latitude in each hemisphere. 23. a wind blowing from the west. 24. a narrow variable band of very strong predominantly westerly air currents encircling the globe several miles above the earth. 25. Measures atmospheric pressure.

Down 1. Big body of air. 2. are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the North and South Poles towards low-pressure areas within the Westerlies at high latitudes. 3. Reversal of the normal behaviour of temperature in the troposphere. 5. Concentration of water vapour present in air. 9. Rain is this 11. a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain (the wet monsoon ), or from the northeast between October and April (the dry monsoon ). 14. The heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature. 17. a weather system with high atmospheric pressure at its center, around which air slowly circulates in a clockwise (northern hemisphere) or counterclockwise (southern hemisphere) direction. Anticyclones are associated with calm, fine weather. 18. The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form. 20. a system of winds rotating inward to an area of low atmospheric pressure, with a counterclockwise (northern hemisphere) or clockwise (southern hemisphere) circulation; a depression.
