If there were periods of deposition between the two periods, erosion has removed all trace.
Overgrazing and erosion have removed much of the topsoil from the island.
Later, erosion (perhaps wind which can't move large rocks) removed much of the surface layers, but left behind the more resistant deposits.
The road collapsed along one edge where erosion had removed the soil beneath.
Weathering and erosion remove any rock that is exposed at the surface of the Earth.
In the following million years geological movements carried it to the surface where erosion removed large amounts.
Later erosion removed material around the crater, but left a mound in the crater that was higher than its rim.
Pleistocene erosion removed the younger rocks, exposing the current strata.
When erosion removes the overlying rock material, these intrusive rocks are exposed and the pressure on them is released.
As this subsurface movement of salt shaped the landscape, erosion removed the younger rock layers from the surface.
