How has weathering affected Cleopatra's needle?
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

What are the three main causes of weathering?
The three main causes of weathering are physical weathering (e.g. wind, water, and ice), chemical weathering (e.g. oxidation and hydrolysis), and biological weathering (e.g. plant roots and burrowing animals). These processes break down rocks and minerals into smaller particles over time.
The major cause of weathering and erosion is?
Wind and water are the major causes of weathering and erosion.
