Fill in the blanks to complete the passage. Geologists can use ________ waves to learn about Earth’s interior. P waves travel fa
Kisachek [45]

Answer:

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.

The numbers listed represent the number of electrons in the first, second, and third energy levels, respectively. On this basis,
yulyashka [42]

Answer:

D

Explanation:

This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction.  Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
