  1. Difference between weather and climate: - Weather refers to the short-term atmospheric conditions in a specific location, such as temperature, humidity, precipitation, and wind. Climate, on the other hand, refers to the long-term average weather patterns in a region.

  2. Earth-Sun relations: - The Earth’s tilt and orbit around the Sun play a significant role in determining weather and climate patterns. The angle of sunlight affects the distribution of solar radiation on Earth, leading to seasonal changes.

  3. Global radiation and temperature: - The amount of solar radiation received by different parts of the Earth’s surface varies based on factors such as latitude, altitude, and cloud cover. This uneven heating leads to temperature variations across the globe.

  4. Precipitation and Fog: - Precipitation occurs when water vapor in the atmosphere condenses and falls to the ground as rain, snow, sleet, or hail. Fog is a type of low-lying cloud that forms when air near the ground cools and reaches its dew point.

  5. Atmospheric circulation: - The movement of air masses around the Earth is influenced by factors such as temperature, pressure, and the Earth’s rotation. This circulation pattern helps distribute heat and moisture across the planet, leading to different weather patterns.

  6. Storms: - Storms are intense weather events characterized by strong winds, heavy precipitation, and sometimes thunder and lightning. Common types of storms include thunderstorms, hurricanes, and tornadoes.
