Answer:

D. Reversal of Earth's magnetic field

Explanation:

The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.

Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.

Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.

<u>Answer:</u>

The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.

<u>Explanation:</u>

  • When "seafloor spreading" occurs along the mid-oceanic ridges, it results in a drastic splitting of the oceanic floor over a large area.
  • This in return changes the orientation of the predominant magnetic fields and the intensity of their strength in the region.
  • The mid-oceanic ridges are majorly constituted of solidified lava which is rich in iron.
  • The changes that occur in the local magnetic fields due to seafloor spreading thus create magnetic changes along the mid-oceanic ridges.

goldfiish [28.3K]

Answer:

Negative

Explanation:

Aerosol -

It is the suspension of the solid or liquid particles in the air , is known as the aerosol .

The effect of aerosol is , that it reduces the amount of the solar radiations incident on the surface of the Earth , and due to this capacity to reflect the solar radiations , it has a negative impact on the Earth .

As we known solar energy are of huge importance for the human beings .

Hence , the answer is negative .

If the half life for strontium-90 is approximately 28 years, then what is the whole life for strontium-90?
sveta [45]
Set this up as

10 = 40 (1/2)t/28

and solve for t in years.

10/40 = (1/2)t/28

log(0.25) = (t/28) log(0.5)

t = 28 log(0.25) / log(0.5) years = 56 years

Test the answer:

56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
