What type of rock is typically softer and more prone to erosion than igneous rocks?

Sedimentary rock is typically softer and more prone to erosion than igneous rocks due to its formation process. Sedimentary rocks form from the accumulation and compaction of mineral and organic particles over time, which can make them more fragile and less dense compared to igneous rocks. The layers that compose sedimentary rocks often include materials such as clay, silt, sand, and pebbles, which are cemented together. This layered structure can easily break down over time, especially when exposed to weathering processes like wind and water erosion.

In contrast, igneous rocks—such as basalt and granite—are formed from the cooling and solidification of molten material (magma or lava), which typically results in a much harder and denser structure. This increased toughness gives igneous rocks superior resistance to erosion compared to sedimentary rocks. Therefore, sedimentary rocks are more susceptible to being broken down and worn away, contributing to their classification as softer in the rock cycle.
