Some environmental changes are visible, such as a landslide caused by heavy rains. Other changes are not as easy to see. For example, some geologic change, like sediments becoming sedimentary rock, is too slow for the eye to see. Occasionally, only the effects of environmental change are visible and we have to search to find the cause, as in the receding of glaciers caused by climate change.
