  1. The south-west monsoon, also called the summer monsoon, blows from June to September, carrying moist winds from the sea (Indian Ocean, Arabian Sea, and Bay of Bengal) towards the land due to a low-pressure area over India, and it brings most of the country's annual rainfall.

    The south-west monsoon, also called the summer monsoon, blows from June to September, carrying moist winds from the sea (Indian Ocean, Arabian Sea, and Bay of Bengal) towards the land due to a low-pressure area over India, and it brings most of the country’s annual rainfall. The north-east monsoon, also called the winter monsoon, occurs from October to February; it blows cold, dry winds from land to sea and generally does not bring rainfall, except when it picks up moisture over the Bay of Bengal and causes rainfall along the eastern coast, especially Tamil Nadu, Andhra Pradesh, and parts of Karnataka.

  2. Aeroplanes fly in the stratosphere, which extends up to about 50 km above the Earth's surface. This layer is ideal for flying because it is free of clouds and other weather disturbances, unlike the troposphere below it where rainfall, fog, storms, and other weather phenomena occur. The stable, calmRead more

    Aeroplanes fly in the stratosphere, which extends up to about 50 km above the Earth’s surface. This layer is ideal for flying because it is free of clouds and other weather disturbances, unlike the troposphere below it where rainfall, fog, storms, and other weather phenomena occur. The stable, calm conditions in the stratosphere make air travel smoother and safer.

  3. We do not feel the pressure of the atmosphere because the air presses on our bodies from all sides equally, and our bodies exert an equal counter-pressure in response. The pressure inside our bodies is equal to the atmospheric pressure outside, so the two forces cancel each other out, and we remainRead more

    We do not feel the pressure of the atmosphere because the air presses on our bodies from all sides equally, and our bodies exert an equal counter-pressure in response. The pressure inside our bodies is equal to the atmospheric pressure outside, so the two forces cancel each other out, and we remain unaware of the constant force being exerted on us.

  4. The Indian Meteorological Department (IMD) has recognised four distinct seasons in India: Winter (December to early April), Summer or pre-monsoon (April to June/July), Monsoon or rainy/advancing monsoon (June to September), and Post-monsoon or retreating monsoon (October to December). The HimalayanRead more

    The Indian Meteorological Department (IMD) has recognised four distinct seasons in India: Winter (December to early April), Summer or pre-monsoon (April to June/July), Monsoon or rainy/advancing monsoon (June to September), and Post-monsoon or retreating monsoon (October to December). The Himalayan states additionally experience two more seasons, autumn and spring, due to their more temperate climate.

  5. The atmosphere has five main layers, arranged from the Earth's surface outward: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere. The Troposphere (up to ~12 km) is where temperature decreases with altitude and all weather phenomena occur. The Stratosphere (up to 50 km) contains theRead more

    The atmosphere has five main layers, arranged from the Earth’s surface outward: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere. The Troposphere (up to ~12 km) is where temperature decreases with altitude and all weather phenomena occur. The Stratosphere (up to 50 km) contains the ozone layer and is ideal for flying aeroplanes. The Mesosphere (up to 80 km) is where temperature again decreases with altitude and meteorites burn up. The Thermosphere (80–700 km) has rapidly rising temperature and contains the ionosphere, where auroras occur. The Exosphere is the outermost layer with very thin air, where light gases escape into space. (A labelled diagram showing these layers with increasing height on the vertical axis should be drawn, marking the boundaries: tropopause, stratopause, and mesopause.)
