Climate and Weather - Seasons, Weather Instruments
This chapter in Class 4 EVS (Our Wondrous World) explores the fascinating atmospheric conditions that shape our daily lives. Students will learn the difference between daily weather and long-term climate, understand the main seasons experienced in India (Summer, Monsoon, Winter, Spring, and Autumn), and discover how meteorologists measure atmospheric conditions using essential weather instruments like the thermometer, rain gauge, and wind vane. Mastering these concepts is crucial for ICSE Social Studies exams, as questions frequently test observational skills, definitions of weather elements, and the practical uses of meteorological instruments.

Frequently Asked Questions
What is the main difference between weather and climate?
Weather changes every day or even every hour (like it being sunny today and rainy tomorrow). Climate is the usual weather of a place averaged over many years.
Why do we have different seasons?
We have different seasons because the Earth tilts on its axis as it travels in a path around the sun, changing the amount of sunlight different parts of the Earth receive.
How does a rain gauge work?
A rain gauge is an open-topped container with a measuring scale inside that collects rainwater so we can read how many millimeters of rain have fallen.
