Answer:
D
Explanation:
I believe its D because we cross out the first 2 options because the question is asking about the dark line which is the pups and not the adults. if we look D and the lowest point of dark line, we can say its talking about <u>few</u> and 1995 talking about <u>many. </u>
B. acidity...
hope this helps and HAGD!
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.
it’s D and E the second last and last one literally just did it you’re welcome
Its protons because we know electrons= protons so its postive so a)
