Granite has been around for 4 billion years
With With enough heat and pressure, granite will become gneiss so long as it is not hot enough to melt the granite.
Granite is a very resilient type of rock and is not prone to much erosion. types of erosion that could occur to granite are acid rain, coastal erosion (weather and salt from the sea damaging it) and weather erosion. it would take an extremely long period of time for erosion to become apparent.
granite
a long time. Acid rain and other erosion methods erode the rock to form a cave then an arch then a stack
Millions of years
Wind erosion is an ongoing process.
Because wind and rain erode it.
18 000 years to form because water had to erode it away

Over long periods of time, the action of the surf upon the cliffs will further erode them. Water and the force of the water will cause erosion as well as the constant pelting of sand/debris laden water on rocks/cliffs.
The answer is in the question. Natural granite and engineered granite are like steak and beefburger. However, engineered granite is probably more practical and cheaper in the long run. See link.
I am not quite sure but the nature of wind and water can erode the form and shape of it so it may not stay put long enough to last well forever.
From my understanding, "you get what you pay for", so although you can buy cheap granite counter tops, it is likely that they will crack or chip, and overall not last as long as the high quality granite.
Most likely it would have been subjected to far more weathering; in paticular, a type ofphysical weathering called frost wedging. Cleopatra's needle is carved of granite and when exposed to constant freezing and thawing in severe climates such as most of Siberia experiences granite exhibits this type of weathering. Granite typically has small cracks and fissures or joints which can fill with water. Even though Siberia is relatively dry some water would be available to do this (over long periods of time especially). Water expands when it freezes which causes a wedging effect inside the crack and causes plates of rock to crack off. Over time this would most likely happen to Cleopatra's Needle in Siberia
