Q. Why do Unconformities occur?

Unconformities occur when either erosion wears away rocks, or rock deposits never form. Therefore, a time gap exists between when the rocks below the unconformity formed and when those above it formed. Common to all three, erosion causes them to form, and younger rocks sit on older rocks.

Q. How do you identify an unconformity?

Q. Why are Zion Rocks Red?

Thin beds of clay and silt mark the end of this formation. The most prominent outcrops of this formation make up the capstone of The West Temple in Zion Canyon.

Q. How were the rocks in Zion formed?

Zion was a relatively flat basin near sea level 240 million years ago.
