The Ozone Layer: Protecting Ourselves from the Sun's Fury The ozone layer, a fragile shield in the Earth's stratosphere, protects us from the harmful ultraviolet (UV) radiation emitted by the sun. This radiation can cause sunburn, skin cancer, cataracts, and damage ecosystems. Understanding the threats to the ozone layer and international efforts to mitigate them is crucial for safeguarding our planet.
Discuss how seismology throws light on the constitution of the interior of the earth. पृथ्वी की आंतरिक संरचना पर भूकम्प विज्ञान किस प्रकार प्रकाश डालता है ? व्याख्या कीजिए । (40 marks, JPSC 2019) The Earth, unlike a familiar apple, cannot be sliced open to study its internal structure. Seismology, the study of earthquakes and seismic waves, emerges as a crucial tool for piecing together this intricate puzzle. By analyzing the behavior of these waves as they travel through the Earth's interior, scientists can unveil the hidden composition and structure of our planet.
