| Define: Ocean Current | The flow of a large body of water in an ocean. |
| Define: Prevailing Wind | The most frequently occurring wind direction in an area. |
| Define: Storm Surge | High onshore winds and tides combine to give unusually high sea levels. |
| Define: Solar radiation | Radiation emitted from the sun. |

| Define: Convection | Transfer of heat through convective (Circuit like) movement of air. |
| Define: Terrestrial radiation | Radiation emitted from the earth. |
| Define: Trade winds | Surface prevailing winds which blow from subtropical high pressure cells towards the Equator |
| Define: Advection fog | Fog created when warm moist air comes into contact with a cold surface. |
| Define: Inversion layer | Air layer where temperature rises rather than falls with height. |
| Define: Inter-tropical convergence zone | an area of rising air, low pressure, converging surface Trade Winds and high temperatures coincident with the Equator. |
| Define: Coriolis force | Deflection of global winds by the rotation of the earth. |
| Define: Polar Front | Boundary abnout 50-60 Degrees N&S of the equator where cool air from the poles meets warm air from the subtropical high pressure cells producing rain. |
| Define: Alveoles | Small hollows, 5-50cm in size, occurring in clusters or honeycombs with thin partitions strengthened by case hardening. |
| Define: Tafoni | Hollows a few meters across with arch-shaped entrances, often developed along lines of weaknesses such as joints and bedding planes. |
| Define: Case hardening | A hard layer of salt-encrusted rock formed where salts have been drawn to the surface by capillary action. |
