WEATHERED & ERODED STRATA
There are several major layers of rock or STRATA in this scene
from Utah's Capitol Reef National Park, USA. The dominant strata
forming the bold vertical faces are SANDSTONES. In between are
weaker, crumbly layers of rocks that are rich is clay. WEATHERING
processes attack the weaker rocks with most success but fragments
of all the represented rocks accumulate as SCREE (also called
TALUS). So in this view we have vertical CLIFF faces and less
steep SCREE slopes - two essential ingredients of a landscape
- the latter being formed by DEPOSITION or accumulation of WEATHERED
debris. Eventually, this weathered material will find its ways
into streams and will be washed away.
