Answer:

option C

Explanation:

The correct answer is option C                            

Earthquake with magnitude 6 is considered as moderate magnitude of earthquake.

Earthquake with magnitude 4 is considered as low magnitude earthquake.

Difference between the magnitude of the earth quake is 6 - 4 = 2

the difference in the magnitude is 2                    

The earthquake of magnitude 6  is 100 times more stronger than the earthquake of magnitude 4.

Answer:

c) 100

Explanation:

The energy of an earthquake is giben by the following formula:

\log{E} = 5.24 + 1.44M

In which log is the logarithm operation and M is the magnitude.

We can isolate E elevating both sides to 10, which leaves us with 10^{\log{E}} = E on the left side. This is a logarithm property So:

E = 10^{5.24 + 1.44M}

Magnitude 6

Has a energy of

E = 10^{5.24 + 1.44*6} = 7.59 \times 10^{13}

Magnitude 4

Has a energy of

E = 10^{5.24 + 1.44*4} = 10^{11}

So the earthquake of magnitude 6 is \frac{10^{13}}{10^{11}} = 100 times more energetic.

If the East pacific rise is the source of new rock, which trench would contain the oldest
AnnyKZ [126]

The oldest rocks will be found at the Mariana Trench.

Explanation:

There is a general rule when it comes to where the oldest rock of a plate is located and where the youngest rock is located. That is based on where there are divergent boundaries and where there are convergent boundaries. The places where there are divergent boundaries are the places where new crust is formed, thus the closest a place is to the boundary the younger the rock is. The places where there are convergent boundaries are the places that are the furthest away from the places where the new rock is formed, so they are where the oldest ones are.

In this case, we have the Pacific plate. The East Pacific Rise is a place where new crust forms, meaning that the youngest crust is there. The oldest crust will be located in the trenches that are the furthest away from it, and that would be the Mariana Trench, which is also the deepest trench in the world.

Other trenches of the Pacific that would be among the candidates for some of the oldest rocks are:

  • Kuril Trench
  • Japan Trench
  • Kermadec-Tonga Trench

Degger [83]

Answer:

Option (C)

Explanation:

A barrier island is usually defined as a long and narrow type of land that is dominantly comprised of sand particles and are oriented parallel to the coastal mainland.

The presence of a barrier island protects the coastal rocks from getting eroded by the strong water waves, wind, and tidal effects. This acts as a barrier and there lies a lagoon between the coastal landform and the barrier island.

It plays an important role in the ecosystem as it provides valuable nutrients and minerals, supporting a large number of living species.

Thus, the correct answer is option (C).
