Give examples of three occupations in which weather forecasts are essential.

Weather forecasting is the field of science and technology that deals with the prediction of the conditions of the atmosphere in a particular time and in a concerned location. Farmers, air vehicle pilots and space scientists are three occupations that required to know the weather forecasts. Farmers need to know the weather forecast to plan the plantation and harvesting of the crops according to the future weather conditions. Airlines or air vehicle pilots need to know the weather forecast to schedule flights. Space scientists needs to know the weather forecast to schedule the launching of the satellites and spacecrafts.

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
