Here's a breakdown:

* Water erosion: Water, in its various forms (rain, rivers, waves, glaciers), can carve away rock through:

* Abrasion: The force of water carrying sand and gravel particles grinds against rock, wearing it down.

* Dissolution: Water can dissolve certain types of rock, like limestone, and carry it away.

* Hydraulic action: The sheer force of water itself can break apart rock, especially in fast-flowing rivers or powerful waves.

* Wind erosion: Wind can erode rock through:

* Abrasion: Wind carrying sand and dust particles can sandblast rock surfaces, wearing them away.

* Deflation: Wind can pick up and carry away loose rock fragments, leaving behind a hollow or depression.

Erosion is a continuous and natural process that shapes our planet's landscapes.
