Answer:
A stump is formed through a series of erosional processes. This are corrasion (the effects of material suspended in the water being thrown against the headland), and hydraulic action (the effect of the build-up of pressure, as waves compress air in to cracks). Through these processes a fissure will form in a headland, and over time this will widen and deepen in to a crack. This this then continue to be eroded until a cave is formed. Through the erosional processes this cave will eventually be eroded right through, leaving a three-sided landform known as an arch. An example of this is Durdle Door. Over time, the roof of this arch will become unsupported and will collapse, leaving a stack which is unconnected from the headland. An example of this is Old Harry. Over time this stack will be eroded in to a stump, which will eventually disappear completely.

The Earth has been around for approximately 4.6 billions of years. Humans first evolved from I believe apes around 5 million years ago, with Homo Sapiens evolving around 2 million years ago or so. The current calendar system we use today, the Gregorian system (in most western nations like America) marks the year 0 as the year Jesus Christ was born, not when the Earth was formed. Years before Jesus' birth are marked as B.C., with the numbers getting higher the earlier you go. In the Japanese system, the year is marked by how long the current Emperor has been in power, making the current year (2017) Heisei 29 in traditional Japanese calendars.

Answer:
D none of the above
Explanation:
Answer would be Birth rate and Economic development, But was not on there. But here is more understanding of it
.
The factors that cooperate for population growth are the high birth rate (number of births) alongside the decrease in infant mortality, economic development and the increase in life expectancy of the population.
Such an increase in life expectancy is the result of improvements in health systems, advances in medicine and basic sanitation and adequate hygiene for populations.
