Dr. Manishika Jain explains NCERT Class 7 Science Chapter 7: Weather, Climate and Adaptations of Animals to Climate

Activities are planned based on predicted weather & place
Weather
Information on temperature (Max & Min), humidity (Max & Min), wind and rainfall for last 24 hours – day to day condition
These are known as elements of weather
Complex phenomena and varies over very small time
By Meteorological Department of Govt.
Rainfall is measured by rain gauge
Maximum and Minimum Thermometers (Chapter 4) – maximum temperature in afternoon while minimum in early morning
Sun plays a major role - Energy absorbed and reflected by the earth’s
surface, oceans and the atmosphere play important roles in determining the weather at any place
Sunrise and sunset timings change

Climate
Weather records preserved for several decades – around 25 years or more
If temperature is high, we say climate is hot
Find average over month; across months and average of such averages over many years
West India – Arid and semi-arid
