What process is responsible for creating magnetic changes along mid-ocean ridges? A. Ridge push B. Slab pull C. Seafloor spreading D. Reversal of Earth's magnetic field

Answers

Answer 1

Answer:

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.

Answer 2

Answer:

Answer:

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

Explanation:

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.

Which of the following best describes the action that is creating the rift valley in Africa?(a) the african plate is colliding with the aribian plate

(b) the afriacn plate is spreading apart to form two seperate plates

(c) the eurasian plate is converging with the afriacn plate

(d) the eurasian and aribian plates are diverging

Answers

The correct is - (b) the African plate is spreading apart to form two separate plates.

The African tectonic plate, on of the biggest ones, but it will not be like for a long time in the future as the plate is separating into two parts. The eastern part of the plate is moving towards east, and it is moving away from the mainland Africa. Because of this movement, cracks have been forming all over the eastern side of Africa, thus the numerous faults. Over time, as the distance is increasing, the space in between will fill with ocean water, thus making a natural barrier between them, as well as setting the foundations for the creation of a new sea, or maybe even an ocean.

Explain on a complete sentence why it is important for scientific to share information whit one another

Answers

Good Morning! From the beginning of science it has been understood that different experiments bring different results. The sharing of information, in this sense, acts on the contribution of accumulated knowledge to the subsequent production of new discoveries and innovations. Think of it this way: if the individual who created the ways of storing energy had not provided and shared his invention, would it be possible for the inventor, for example, from the radios to the pile to have succeeded? This small example illustrates the fundamental relationship between the various researches and discoveries, revealing the importance of information sharing, which also contributes to the improvement. Hugs!

Scientists share information with one another so that results can be replicated and used to develop scientific knowledge.

This is the correct answer, on e2020 at least. Hope this helps!
