Which information is needed to construct a geomagnetic time scale?
AleksAgata [21]

Answer:

the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth

Explanation:

The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.

During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.

To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.

How does natural selection impact a population
statuscvo [17]

Answer:

People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.

Explain why a plant that does not get enough nitrate has weak growth
blagie [28]

Answer:

Nitrate deficiency

Explanation:

Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
