Question

which event most likely occurs at point k?
cooling
cementing
melting
weathering

Explanation:

The diagram shows the rock - cycle. Igneous rock can transform into sediment through weathering and erosion. Weathering is the breakdown of rocks into smaller pieces by physical, chemical, or biological processes. Erosion is the movement of these weathered materials. Since the arrow leading from igneous rock to sediment is labeled "Weathering and Erosion", the most likely event at the point (assuming it is on this arrow) is weathering.

Answer:

weathering
