The ability to grow in size is characteristic of living organisms. although an icicle may
grow in size over time, it is considered nonliving because there is
(1) an increase in matter, but no increase in the number of icicles
(2) an interaction between the icicle and the environment
(3) no way for the icicle to move away from heat
(4) no metabolic activity present

what are the options

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
