PLZ HELP Which statement correctly describes the main difference between body waves and surface waves?
Select one:

Surface waves are only longitudinal waves and body waves are only transverse waves.

Surface waves only travel across oceans and body waves travel across the Earth’s crust.

Surface waves are less damaging to man-made structures than body waves.

Surface waves travel across the Earth’s surface and body waves travel through the Earth’s interior.

Surface waves travel across the Earth’s surface and body waves travel through the Earth’s interior.

there you go :)

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023
