Understanding the Weather
Sunshine, wind, clouds and rain change every day, and their daily state is the weather. This chapter of the NCERT Class 7 Social Science textbook introduces its elements: temperature, air pressure, humidity, wind and precipitation. It explains how the sun heats the earth unevenly, how air moves, how clouds form and rain falls, and how instruments such as thermometers, barometers, anemometers and rain gauges measure each element. Simple observations help learners read weather reports and understand seasons in their own region.
