    Soil Pollution

    Soil pollution refers to the degradation of soil quality due to harmful substances, affecting the environment and food chains.

    Learning Practice

  • 14.6

    Ozone Layer And Its Depletion

    The ozone layer protects the Earth from harmful ultraviolet (UV) rays, but its depletion due to CFCs poses severe health and environmental risks.

    Learning Practice

  • 14.7

    Global Warming

    Global warming is primarily caused by the emission of greenhouse gases that trap heat in the Earth's atmosphere, leading to significant environmental changes.

    Learning Practice

  • 14.8

    Acid Rain

    Acid rain is a form of precipitation that contains acidic components, primarily from sulfur dioxide (SO₂) and nitrogen oxides (NOx) that combine with water vapor.

    Learning Practice
