Exploring Structures With Waves

Question 1

When there’s an earthquake, it produces _______ _____ which can be detected using ____________

Answer 1

1) seismic waves

2) seisometers

Question 2

When seismic waves read a boundary between different layers of material inside the earth, some waves will be…

Answer 2

absorbed and some will be refracted. If the waves are refracted, they change speed gradually, resulting in a curved path. But when the properties change suddenly, the wave speed changes abruptly and the path has a kink

Question 3

Difference between P waves and S waves

Answer 3

P waves can travel through the earths core, can travel through solids and liquids and are longitudinal waves

S waves are transverse, can’t travel through liquids or gases and can’t travel through earths core
