Geologists define a geological formation as __________?

• A rock that has been completely lithified

• A recognizable, mappable rock unit

• A transgressive overlap

• A uniquely shaped rock feature

What does the strike and dip of a rock represent?

• Dip is the thickness of the bed and strike is how steeply it is inclined

• Strike is the angle by which a rock is hit by a rock hammer

• Strike is the offset of fault and dip in the area exposed by the faulting

• Dip is the angle of greatest inclination down from horizontal and strike is the angle from true north or true south of a horizontal line on the stratum
