Question 4

You have seen weather reports on television and in newspapers. How do you think we are able to predict the weather?

Answer

A daily weather forecast is the work of people working for the weather department to collect data on the elements of weather such as maximum and minimum temperatures, maximum and minimum humidity, rainfall, wind speed, etc. Weather satellites are present to take photographs of clouds from space. The maximum and minimum temperature of a day is measured by a thermometer known as the maximum−minimum thermometer. Rainfall is measured by an instrument known as the rain gauge. Wind speed is measured by anemometers. There are various instruments used to measure humidity.
