Question 1

Give 3 characteristics of primary waves

Answer 1

Fast
Compressional
Longitudinal

Question 2

Give 2 characteristics of a secondary wave

Answer 2

Transverse

Slow

Question 3

what can primary (P waves) travel through

Answer 3

Solids
Liquids
Gases

Question 4

What can secondary (S waves) travel through

Answer 4

solids only

Question 5

What waves and in what order are transmitted from an earthquake

Answer 5

Seismic waves, P then S

Question 6

Difference between a longitudinal wave and a transverse wave

Answer 6

In longitudinal waves the oscillations are along the same direction as the direction of travel and transfer energy by moving back and forwards -LEFT AND RIGHT (don’t go up and down)

Whereas in transverse waves the oscillations (vibrations) are at right angles to the direction of travel and energy transfer and moves up and down

Question 7

Example of longitudinal waves

Answer 7

Sound waves

P waves

Question 8

Example of transverse waves

Answer 8

S waves
water
light and all other em waves

Question 9

What is a seismic wave

Answer 9

waves of energy and vibration caused by a sudden breaking of rock within the earths crust or on its surface

Question 10

What can seismic waves do

Answer 10

Seismic waves can be reflected and refracted at boundaries between the crust, mantle and core. This means that they change direction.
