Define earthquake and explain why earthquakes occur.
Answer
An earthquake is the shaking of Earth caused by release of energy. It occurs when rocks along a fault (sharp break in crustal rocks) try to move in opposite directions. Friction initially locks them t…

Compare P-waves and S-waves in terms of speed, materials they travel through, and wave motion.
Answer
P-waves: Faster (primary waves), travel through gaseous, liquid, and solid materials, vibrate parallel to wave direction (compression waves). S-waves: Slower (secondary waves), travel only through sol…
What is a shadow zone and why do P-waves and S-waves have different shadow zones?
Answer
Shadow zone is an area where earthquake waves are not recorded. P-wave shadow zone: 105°-145° from epicentre (waves bend due to liquid outer core). S-wave shadow zone: Beyond 105° from epicentre (40% …
List and briefly explain the five types of earthquakes based on their causes.
Answer
1) Tectonic earthquakes - sliding of rocks along fault planes (most common), 2) Volcanic earthquakes - in areas of active volcanoes, 3) Collapse earthquakes - underground mine roof collapse, 4) Explos…
What is the difference between Richter scale and Mercalli scale for measuring earthquakes?
Answer
Richter scale measures magnitude (energy released) expressed in numbers 0-10, based on seismograph readings. Mercalli scale measures intensity (visible damage caused) with range 1-12, based on observe…
Describe the structure and characteristics of Earth's crust.
Answer
Crust is the outermost solid layer, brittle in nature. Oceanic crust: thinner (5 km average), Continental crust: thicker (30 km average, up to 70 km in Himalayas). Made of lighter rocks, separated fro…
