Fill in the blanks to complete the passage. geologists can use waves to learn about earth’s interior. p waves travel faster than s waves. s waves travel through solids only, which tells geologists that the core is liquid. geologists call the outer, solid area of earth the crust; the next layer is the finally, at the very center, is the core.

Seismic waves,    Outer,    Mantle

Explanation:

P-waves vibrate longitudinally to the direction of propagation while S-waves vibrate vertically to direction of propagation. This is why S-waves are called shear waves while P-waves are compressional waves. S-waves are the main cause of destruction in an earthquake and are slower than P-waves.

The wave movement of P-waves allows them to pass through liquids and gases while S-waves cannot. Due to this differential phenomenon of these waves, the reflection of P –waves and S-waves after an earthquake – and as their vibrations are picked up by seismographs around the earth - enabled scientists to determine the properties of the  layers of the earth’’s interior.

Geologists can use Seismic waves to learn about Earth’s interior. P waves travel faster than S waves. S waves travel through solids only, which tells geologists that the Earth's core is liquid. Geologists call the outer, solid area of Earth the crust; the next layer is the Mantle. Finally, at the very center, is the core.

Explanation:

Researchers can comprehend Earth's inside by contemplating seismic waves. These are floods of vitality that moves through Earth and they move correspondingly to different sorts of waves, similar to sound waves, light waves, and water waves.

The earth is made up of three layers namely Crust (the outer layer) is solid, mantle (the middle layer) which is liquid and core (inner layer) which is very hot. Thus the correct answer for the blanks given in the passage is: Seismic waves, Earth and Mantle.

the correct answer is ( hypoglycemia ); good luck
