Around half of the projected increase in the numbers of children in relative poverty is ascribed by the IFS to the Government’s cuts and all of the increase in absolute poverty is due to ministers’ fiscal decisions.

Imran Hussain, director of policy for the Child Poverty Action Group, said: “There is no greater burning injustice than children being forced into poverty as a result of government policy.

The disadvantage of such methods is that the necessary evidence is frequently either not preserved or not exposed.

The so-called ‘absolute’ (physical, numerical) methods, and especially those based on exposure age dating with in situ cosmogenic radionuclides, are appealing because they produce direct numerical ages, and appear to be widely applicable, but there are severe temporal limitations, and sampling problems complicate, and may invalidate, interpretation.

The dating of land surfaces has long posed problems for geomorphologists.

Relative methods (stratigraphic, geomorphic, topographic) are sound and convincing.

By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years.

Relative dating establishes the sequence of physical or cultural events in time.

Knowing which events came before or after others allows scientists to analyze the relationships between the events.

Exhumed forms may complicate identification and relationships, for both epigene and etch forms have been buried, and exhumed, but in tectonically undisturbed areas, the higher surfaces are older than those preserved at lower levels. The relationship of surfaces with volcanic deposits, old shorelines, and genetically related sedimentary sequences provides sound ages, and correlation with dated duricrusts and faults is also useful.

There are no temporal limits to relative dating, for the methods are equally applicable to the dating, say, of Proterozoic surfaces as of those of Pleistocene age.

Consider a lake that dries out or somehow contains older sediments that are washed into it.
