GEOLOGY

Detailed explanation-1: -P wave are like Sound waves and can travel in all the three mediums of solid, liquid and gas. Hence statement 1 is correct.

Detailed explanation-2: -Answer and Explanation: The only statement that is true is that the p-waves or primary waves travel faster, and thus arrive sooner than do the s-waves or secondary waves which is choice B.

Detailed explanation-3: -In a P wave, the rock particles are alternately squished together and pulled apart (called compressions and dilatations), so P waves are also called compressional waves. These waves can travel through solids, liquids, and gases. P waves can travel through the liquid outer core. An S wave is a different beast.

Detailed explanation-4: -P waves can move through solid rock and fluids, like water or the liquid layers of the Earth. It squishes and stretches the rock it moves through just like sound waves compress and expand the air as they move through it.

Detailed explanation-5: -It can pass through solid, liquid and gas. P-waves travel at the fastest speed through solid materials. Though these also pass through liquid and gaseous materials their speed is slowed down.
