Why is top soil good for plant growth?
in topsoil they can absorb the amount of water and the nutricient they need plus the soil must not be completely wet because the roots rot and they also need air in the roots. in subsoil there is more water and causes diseases to the roots and there is not enough air.so topsoil has less humus
Why does the asthenosphere have plasticity?
Because it is exposed to high temperature, but not enough to melt it.
Why do sediments have angular or rounded fragments?
Angular sediments are usually young or "immature" sediments which have only recently been weathered from a source rock. They have not been exposed to corrosive fources long enough to become worn down. These sort of sediments are common in glacial areas or areas high in a river catchment near their original location.Rounded grains suggest extended periods of transport and mechanical weathering, which chip away the sharper edges of the immature sediments leaving them worn dow. a common example of this is a desert sand, which has been exposed to errosive forces for a long time, being blown around the desert, giving them a rounded appearance.Think of a broken piece of glass. In its "immature form, it has sharp edges and smooth faces. If you throw it in the ocean on a beach, and give it time, the surf and sand will weather it smooth, leaving you with nice smoth beach glass, a mature sediment.
Why is sodium called a photosensitive metal?
It is so small that when sodium is exposed to the sun light, the energy of sun light is enough to cause the ionization of sodium metal. Hence it is called a photo-sensitive metal.
How harmful is silver nitrate?
If ingested by mouth silver nitrate is a deadly poison and only small quantity is enough to kill a person. If dilute solutions (1M) contact exposed skin, the skill will become dyed dark brown after it is exposed to ultraviolet light. This is only temporary until the skin cells dye and wear away to be replaced by new ones. This usually takes 2-4 days.

Why can 't seeds germinate in the subsoil?
Seed normally require heat, water and either darkness or light to germinate (the last two depending on the type of seed). In the subsoil the temperature is too low for germination to take place and if it does the cotyledons and primary shoots probably wont have enough food reserves to push the shoot all the way to the surface - meaning the seedling will die
