Potassium-Argon dating has the advantage that the argon is an inert gas that does not react chemically and would not be expected to be included in the solidification of a rock, so any found inside a rock is very likely the result of radioactive decay of potassium. Since the argon will escape if the rock is melted, the dates obtained are to the last molten time for the rock. Since potassium is a constituent of many common minerals and occurs with a tiny fraction of radioactive potassium-40, it finds wide application in the dating of mineral deposits. The feldspars are the most abundant minerals on the Earth, and potassium is a constituent of orthoclase, one common form of feldspar.

Answer:
D is a spit. It is produced as a result of longshore drift conveying sediment through the beach and accumulating the sediments at a hurdle.
Explanation:
Spits are a product of deposition of sediment - which is a result of constant supply of longshore drift due to an alteration in the way or shape of a coastline. It is an extended stretch of beach substances which links to the mainland out of the sea at a certain end.
A typial form of a spit is Spurn Head, located in the north east of England at the north of the Humber Estuary. It is formed as a result of deposition of material from the erosion of the Holderness Coast in the north direction. Another example is Spurn Head in Yorkshire.

Answer:
The process through which a cell transforms from one cell type to another is known as cellular differentiation. In most cases, the cell transforms into a more specialized form. As a multicellular organism develops from a basic zygote to a complex system of tissues and cell types, it undergoes many stages of differentiation.
