If the top layer of your nail is falling apart, you might have a vitamin B deficiency. You could also lack minerals that make your fingernails strong. You might also be having a reaction to a chemical that you touched.

The top layer of soil where grass grows is called Humus. The next layer is the topsoil, and the layer after that is the subsoil.
The top layer is litter, the second layer is topsoil, the third layer is subsoil, and the last layer is bedrock.
the top most layer of soil
the sun heats the top layer of the sand and not the bottem bit
No because while your filing your nail polish off, your damaging the top layer of your nail
falling in water
It depends on the nail polish, but there should be at least ONE application of the color you want on your nails. Let dry. For extra boldness and to even out any mistakes, put on a second layer. Let dry. To make your nail polish last as long as possible, add one layer of clear nail polish on top and you're done!
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
Nail varnish is the coloured polish, and that goes on first. The french polish is just a see-through layer that is a strengthener/hardener to make the coloured varnish last longer and that goes on top after you have applied 1 to 2 coats of the coloured nail polish.
you put it under nail polish
In the epidermis (the top layer of the skin), there are 5 layers. The bottom layer (The Germinating Layer) has cells that continuously divide by a process know as mitosis. The cells are forced upwards into the next layer (the Prickle Cell Layer), where cells are also constantly dividing. By the time the cells get to the top of that layer, they are dying. The next layer is called the Granular Layer and are slowly forced upwards (although they are dead). Cells go on into the next layer (The Clear Layer) and finally reach the top layer (The Horny Layer) where they are continuously shed. They are then replaced by new ones that have been through the same cycle. The skin is constantly growing new cells and replacing dead ones that are falling off. hope this helps :)
The top layer of soil is the most fertile layer. It is the best for growing crops.
No, It is a nail hardener.
That would be the 2nd layer, the stratosphere layer with the ozone at top.
The skin layers from top to bottom are the epidermis (top layer), dermis (middle layer), and hypodermis (bottom layer).
In the food pyramid we have: The top, smallest layer, consisting of fatty foods and candy The 2nd layer, with meat, fish, poultry and dairy products The 3rd layer, vegetables And the widest layer, the 4th layer, with cereals, bread, rice, pasta etc. Apart from that one should drink about 3 glasses of water each day.
