a). Briefly explain the following elements of weather: i. Temperature ii. Humidity iii. Rainfall
Answers
Answer:
part 1.- Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time.
part 2- Climate: the weather conditions prevailing in an area in general or over a long period.
i. Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases. Temperature is measured with a thermometer or a calorimeter.
ii. Humidity is the measure of the actual amount of water vapour in the air, regardless of temperature. The higher the amount of water vapour, the higher is the absolute humidity.
iii. Rainfall is a measurement of how much water falls as rain in a certain period of time, for example, a week or a month. Rainfall is measured by collecting rain water across different areas and times, as the amounts may differ between locations and times.

Explanation:
(i) Temperature is the degree of hotness or coldness of a place or a body. Heat Energy is the form of energy, which flows from a hot body to cold body. Conduction is the mode of heat transfer when two bodies come in contact and is primary mode of heat transfer in solids.
(ii) Humidity is the concentration of water vapour present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.
(iii) Rainfall is the amount of precipitation, in the form of rain (water from clouds), that descends onto the surface of Earth, whether it is on land or water. It develops when air masses travel over warm water bodies or over wet land surfaces. ... The clouds eventually release this water vapor, which is dropped as rainfall.
