Answer:

Over the last two centuries the dipole strength has been decreasing at a rate of about 6.3% per century. At this rate of decrease, the field would be negligible in about 1600 years. However, this strength is about average for the last 7 thousand years, and the current rate of change is not unusual.

1. What type of heat transfer causes the movement of tectonics plates.
creativ13 [48]
1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.

The percentage of organic matter in soils managed for agricultural purposes usually decreases each year after initial clearing.
liraira [26]

Answer and Explanation:

It is true fact that organic matter in soil diminishes with time yet it is unseemly to utilize this information for lab manual since we make heaps of changes to recoup natural issue in the dirt before going for another period of editing. Notwithstanding when the yield is reaped, the buildup of the previous harvest goes about as a natural fuel for the following yield. Here and there when we develop vegetable harvest, it rather adds minerals to the soil.

But if there is comparison between earlier soil and current soil, I figure it would be nearly increasingly precise for the as of late cleared soil since here, we can quantify the exhaustion of natural issue plainly. while the soil which had been cultivated and prepared for horticulture before, there probably come different changes because of enormous number of factors.l
