Question 15

what is meant by refkected and refracted?

Answer 15

rebounded]

change of angle

Question 16

if an area is more dense how is it refracted?

Answer 16

if an area is more dense then the angle turns inwards

Question 17

what doe the p waves show about the earths structure?

Answer 17

can be detected widely
except for a shadow w at 103 142 degrees after travelling through the outer core
conclusion that the inner core is solid as the angle then is refracted inwards

Answer 18

103 and 142

Question 19

Answer 19

only detected up to a quarter to 103 degrees then non are detected
showing that the outer core must be liquid

Question 20

Answer 20

quarter to 103 degrees
