The seismic waves that travel through Earth’s interior are
known as the P waves and the S waves, these seismic waves have differences,
first the P waves compress and enlarge the foundations(rocks) as they move
through it, while the S waves, shakes the particles of their medium up and down
and side-by-side. P waves can travel through solid granite, magma, water or
even air, while S waves can only travel through solids, they are unable to
travel through fluids. The P waves are the fastest of all known seismic waves,
it is the first seismic wave to register on the seismograph, while the S wave
is the second one.
Answer:
b
Explanation:
the ratio should be the same so there should be four particles on the left and 2 on the right
1. So that during the experiment, you don't have to waste your time in figuring out what to do.
2. So that the instructions are clear and if there are any misconceptions, you can clear them out BEFORE the experiment.
3. To avoid trouble or risky scenarios.
4. It allows replication, where other scientist perform your experiment to ensure your findings are correct.
5. To avoid error, such as adding too much of salt into water.
Drought
that is the answer, I'm pretty sure
Guessing it’s D. Hope this was helpful!
