Which statement supports the claim that the outer core of Earth is liquid? Choose the correct answer. Answer Choices:
P-waves do not pass through the outer core.

S-waves do not pass through the outer core.

P-waves travel faster when they enter the outer core.

S-waves pass through the outer core and are refracted.

S-waves do not pass through the outer core.

Explanation:

S - waves do no pass through the outer core and this suggests that this part of the earth's interior is liquid.

S - waves are secondary waves or shear waves.

They do not pass through fluids which are liquids and gases due to their properties. Unlike P- waves, they are cut off where fluids are present.

Therefore, on studying a seismic wave that permeates through the earth, there is an attenuation of S-waves in the core mantle boundary.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
