Sam is given three sets of wooden blocks, as shown. Sam will use the sets to model how rocks change during different parts of the rock cycle. Describe how Sam can arrange the sets of blocks to model how rocks change as a result of weathering. Justify your reasoning.​

Y, Z, X

Explanation:

Weathering is the gradual decomposition of rocks by some of th agents of weathering such as the actions of wind and water.

Stage 1: Y block model the first stage of weathering when the rock is still a whole. It has not been affected by wind or water at this stage

Stage 2: Z block can be used to model this stage. The rock has started decomposing. It has decomposed from a whole rock into 8 small rocks.

Stage 3: X block model this stage. The rock has further decomposed from Z block to X block, that is, from 8 small rocks to 64 smaller rocks

In conclusion,

From 1 whole box to 8 small boxes to 64 smaller boxes

c. seafloor spreading occurs.

d. crust becomes molten rock.

e. denser plates slide under lighter plates.
