EACH ARE 5 POINTS 1 How can scientists use a seismograph to determine the density and depth of Earth's layers? ______________________ 2 Explain three ways that studying seismic waves can help scientists learn about Earth's interior. ______________________ 3 If a seismograph shows only P waves, what does that tell scientists about the location of the earthquake in relation to the location of the seismogram ______________________ 4 Describe the geological events that can occur at a transform boun

number 1 [Scientists send seismic waves through the earth. These travel at different speed]number 2 there are p waves l waves and 3 is s wavesnumber 3 that means that the waves are not very strong because p waves are not very strongnumber 4 A transform fault or transform boundary (also known as a conservative plate boundary, since these faults neither create nor destroy lithosphere), is a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction.number 5 A flash flood is a rapid flooding of geomorphic low-lying areas: washes, rivers, dry lakes and basins.from thatWayLayla hope this helped
