Study Notes
Understanding Weather and Climate
- Weather refers to the temporary and local conditions of the atmosphere at a specific place and time.
Causes of Weather Changes
- Weather changes occur due to various factors, including temperature, humidity, cloudiness, wind, and air pressure.
Seasons and Their Causes
- The main factor causing the Earth's seasons is the tilt of the Earth on its axis.
- The Earth's tilt causes varying amounts of sunlight to reach the Earth's surface, resulting in changes in temperature and seasons.
Climate and Weather Distinguished
- Climate refers to the long-term average atmospheric conditions in a specific region, whereas weather refers to the temporary and local conditions of the atmosphere.
Seasons in India
- India has three main seasons: summer, winter, and monsoon.
The Atmosphere and Wind
- The blanket of air around us is called the atmosphere.
- Wind is caused by the uneven heating of the Earth's surface by the sun, resulting in differences in air pressure.
- A gentle wind is called a breeze.
Evaporation and Water Forms
- When wet clothes are dried in sunlight, the water evaporates into the air as water vapor.
- Water can exist in three forms: solid (ice), liquid, and gas (water vapor).
Additional Facts
- Weather can change from hour to hour and day to day.
- The Earth takes approximately 365.25 days to complete one revolution around the sun.
- Sea breeze blows during the day, while land breeze blows at night.
This quiz covers the concept of weather, explaining how it varies from place to place, hour to hour, and season to season. It also explores the factors, such as the sun's influence, that contribute to changes in weather.
