Answer:

The seismologists have determined the distinct boundaries that are present within the interior of the earth. These have been identified by studying the behavior of seismic waves. These waves include the primary and the secondary waves, commonly represented as P and S waves.

The P waves were found to get deviate as it enters the outer core from the mantle, whereas the S waves get dissolve as it reaches the core-mantle boundary. These data helped the seismologists to understand the changing composition and density of the earth at various depths. This is how the internal layers of the earth were determined.

Scientists can tell by observing the seismic waves that are recorded all over the surface of the earth from distant earthquakes. The seismic waves are reflected (bounced off) layers of different density, and they are refracted (bent) when they enter layers of different density.

The discovery that Earth's inner core rotates independently of and more quickly than Earth's outer layers is responsible for adv
Ivanshal [37]

Answer:

Option (A)

Explanation:

In the above-given question,

Option (B) is wrong with it's usage of the modifier "how'' in the sentence. If the modifier is used in one place (how heat from the inner core flows), it should also be used in the continuing clause (how the formation and periodic reversal).

Options (C) and (D) are wrong in using the word "are" for the whole sentence as there is no need to use this word. The verb form will depend on the subject, in this case, is "the discovery that earth's inner core" which is singular in nature. Thus, the verb form will be -is and not -are.

Option (E) is wrong for it's use of the comma. If the comma is used, then the whole sentence is not a full-fledged sentence but rather a dependent clause with no resolution.

The correct answer for the given passage is option (A).

<h3>Sources of Water for rivers. </h3>
  • Rainfall and the resulting runoff.
  • Water from natural ice.

Both of these come down from mountains and will be impacted by gravity to keep flowing downwards. This then forms or contributes to rivers and explains why mountains are generally next to watersheds.
