Answer:

The answer is "Provide strong evidence for seafloor spreading".

Explanation:

The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.

A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.

In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.

<u>Explanation:</u>

The metamorphic rocks can be identified in some of the following ways. Some of them are rocks changed by the ocean or in the ocean will have salt in them. They are also identified by the amount of water and other minerals found in them. Look at the way the grain are formed.

Alexus [3.1K]

Answer:

D. Ferromagnesian minerals

Explanation:

An igneous rock (formed from the solidification of molten rock material) with a very low silica content (less than 45%), low potassium content and rich in minerals, more than 90% magnesium (MgO) and iron (FeO), is known as ultramafic igneous rock (also known as ultrabasic rocks), they are dark-colored, found in orogenic (mountain-forming) belts and they are used for scientists to understand geological processes in the Earth's history. Examples include peridotite, kimberlite, lamprophyre, lamproite, dunite, and komatiite.

<em>Considering this information we can conclude that D. Ferromagnesian minerals are the correct answer. </em>

I hope you find this information useful and interesting! Good luck!

under new homeland security measures, boats must keep at least how many yards away from all military vessels and ships?
lilavasa [31]

Answer:

100 yards

Explanation:

According to the security measures, all of the boats have to keep a distance of at least 100 yards. Apart from keeping this distance, the boats are also commanded to slow down when they are within 500 yards distance from the military vessels and ships. The reason for this measures is so that the boats don't get in trouble, and so that the military doesn't see them as a danger, seeming to be not obeying orders, or look like they are aggressive.
