What factors – physical, historical, and otherwise – have contributed to the traditional identification of multiple “oceans” ver
Yakvenalex [24]

Answer:

According to this theory, the ocean formed from the escape of water vapor and other gases from the molten rocks of the Earth to the atmosphere surrounding the cooling planet. After the Earth's surface had cooled to a temperature below the boiling point of water, rain began to fall—and continued to fall for centuries.

What is the most likely decay for the fe-53 nucleus?
svetoff [14.1K]
The element number of Fe is 26, which means that the number of neutrons of the following isotopes is: 

<span>53-Fe: 27 </span>
<span>54-Fe: 28 </span>
<span>56-Fe: 30 </span>
<span>57-Fe: 31 </span>
<span>58-Fe: 32 </span>
<span>59-Fe: 33 </span>

<span>Because 53-Fe has too few neutrons when compared to the other isotopes we can rule out any decay that involves losing a neutron: (alpha decay, beta decay) So, this isotope will prefer to decay by electron capture or positron emission (assuming the system has about 1 MeV to spare), but in each case the product will be the same: 53-Mn (long-lived radioisotope). </span>

How humans can improve the negative aspects of soil use FULL SENTENCES 50 POINTS PLEASE HELP
katen-ka-za [31]

Answer:

Using diverse nutrient sources can help maintain soil health. Manure and compost add organic matter as well as an array of nutrients, but using just compost or manure to meet the nitrogen needs of the crop every year can result in excessive phosphorus levels in the soil.
