I would say that igneous rock, because when it is fresh and unaltered can be quite tough to withstand shock would be a better construction material. From experience I believe that the large tightly fitting stones of the Inca fortresses were mostly constructed from igneous rock and it usually stands up well in earthquakes in Peru,
doubling the radius will have a greater effect
v of cylinder=pi x square of radius x hieght
lets take an example,r=2,h=2
v=8pi
doubling the hieght,h=4
v=16pi ie twice the initial volume
doubling the radius,r=4
v=pi x 16 x 2
=32 pi ie four times the initial volume
therefore radius makes a bigger difference

Given that Riley is a human, it's strange to use the terms erosion or weathering to describe her interaction with rocks. Nevertheless, Erosion is the transport of surface materials (soil, rocks, etc.) through the actions of wind, water, and ice, while weathering is the physical/chemical breakdown or change of objects due to weather conditions occuring mainly through the action of wind, water, and temperature on rocks and soil. This coupled with the fact that erosion occurs over a distance makes the best answer weathering.
Answer: Weathering is the breaking down of rocks and minerals on the surface of Earth. Weathering is divided into two types, mechanical and chemical.
Explanation: One of the causes for mechanical weathering is water, either liquid or solid. A cause for chemical weathering is rain water. Rain water reacts with mineral grains in rocks to form new minerals.
