Describe how paleomagnetism is Used to calculate the rate of sea floor spreading?

Geography

qaws [65]3 years ago

Every 50,000 years or so, the magnetic poles of the Earth reverse. As basalt is erupted from sea floor spreading centers, the iron in the basalt aligns itself to the magnetic pole orientation. Paleomagnetism is simply studying the magnetic orientation of iron in old rocks. So, if you have a section of sea floor and you find three zones that record magnetic pole reversals, you know that by the rate of those reversals you are looking at roughly 150,000 years of time.

What other states might have sediments from the Appachian Mountain
Contact [7]
18 States - North Carolina, Ohio, Alabama, Connecticut, New York, Georgia, Kentucky, Maine, Maryland, Massachusetts, Tennessee, New Jersey, New Hampshire, Pennsylvania, South Carolina, Vermont, West Virginia, and Virginia. The Appalachain mountains are found in these states, so it is only logical sediments could be found inside of them.

Suggest at least THREE ways to prevent the negative impacts of population growth on the natural resources.
klio [65]
Erosion of farmland, overuse of both surface and groundwater, dwindling supplies of finite fossil fuels, and escalating extinction of plant and animal species imperil the ability of the earth's resources to meet the needs of such enormous numbers of humans. The food situation worldwide is becoming critical

Shania is trying to determine the oldest geologic unit on this map. Why is she unable to do so?
Anna [14]

B. There is no key on the map

Explanation:

Shania would be unable to determine the oldest formation because there is no key on the map. The map does not contain the proper details to be used to infer age relationships among the formations.

  • A map presents a three dimensional world on two dimensional paper or surface.
  • To infer relative ages, a cross section from the two dimensional representation is the most desired.
  • From the cross section, the third dimension can carefully be studied and ages inferred.
  • There is little to no way we can infer relative age relationship on this surface.
  • To do that, we would require a key. Most times, the key shows the stratigraphic column which puts rocks in their correct ages.
  • Most keys are arranged with formations from the oldest at the bottom and the youngest on top.
  • Since this map lacks a key, direction, scale and other map elements, it would not be possible to infer relative ages of the rock.
