Fill in the blanks using the options below:
s waves (secondary waves), surface waves, p waves (primary waves)

1. waves vibrate both side to side and up and down.
2. wave is the first to arrive during an earthquake.
3. wave may make the ground roll.

1. S waves(secondary waves)

2. P waves (primary waves)

3. Surface waves(Rayleigh waves)

Explanation:

Secondary waves known as s waves is a kind of body waves that travels slowly and usually the rocks it travel is shifted up and down as it travel through it.

Primary waves or p waves is a kind of body waves that travels fast and usually arrive first before any waves during an earthquake. The body it travels is usually compressed and then stretched.

Surface waves comes after the body waves and exist  in the form of Rayleigh and Love waves . As the name exist they are dominant on the earth surface and are known for building collapse . The Rayleigh waves is  known as a ground roll waves because it causes most of the ground shaking.

(4,-2)

explanation:

6x+4y=16

-6x-9y=-6

-5y=10

y=-2

x=4
