Rain is indirectly caused by the sun. The sun’s heat warms water bodies like oceans, rivers and lakes, turning water into vapour through evaporation. This vapour rises into the cooler parts of the atmosphere, condenses into clouds and later falls as rain. Thus, without sunlight, the evaporation-condRead more
Rain is indirectly caused by the sun. The sun’s heat warms water bodies like oceans, rivers and lakes, turning water into vapour through evaporation. This vapour rises into the cooler parts of the atmosphere, condenses into clouds and later falls as rain. Thus, without sunlight, the evaporation-condensation-rainfall cycle wouldn’t occur. This is why ancient texts rightly say “From the sun arises rain.” The sun powers the water cycle, which brings essential rainfall to Earth.

In the temperature chart for Madhya Pradesh, the maximum temperature was 32°C on 3rd March and the minimum was 14°C on 5th March. The temperature range is calculated by subtracting the minimum from the maximum: 32°C - 14°C = 18°C. This means the region experienced a temperature variation of 18°C durRead more
In the temperature chart for Madhya Pradesh, the maximum temperature was 32°C on 3rd March and the minimum was 14°C on 5th March. The temperature range is calculated by subtracting the minimum from the maximum: 32°C – 14°C = 18°C. This means the region experienced a temperature variation of 18°C during the week. This kind of information helps in understanding climate fluctuations and planning daily activities, agriculture or health precautions based on weather conditions.

When the news reports 30 mm of rainfall, it means that rainwater collected in a rain gauge rose to a height of 30 millimetres. A rain gauge is a cylindrical instrument with a funnel that directs rain into a measuring tube. The depth of water collected indicates the amount of rainfall. It’s a preciseRead more
When the news reports 30 mm of rainfall, it means that rainwater collected in a rain gauge rose to a height of 30 millimetres. A rain gauge is a cylindrical instrument with a funnel that directs rain into a measuring tube. The depth of water collected indicates the amount of rainfall. It’s a precise way to monitor precipitation and helps weather departments track rainy days, issue flood warnings and understand seasonal patterns important for agriculture and water management.

Atmospheric pressure is the force exerted by the weight of air above and around us. It varies with height—being highest at sea level and decreasing with altitude. It influences weather systems; for example, low pressure can lead to storms or rainfall. People often feel changes in pressure before bad weather. It is measured in millibars using barometers. Understanding atmospheric pressure is essential for weather forecasting, flying and even human health, especially in high-altitude regions where oxygen is low.
