Base your answers to questions 4 through 7 on the cross section below and on your knowledge of Earth science. The cross section represents rock units that have not been overturned. Lines CC and GG represent unconformities. The geologic ages of some of the lettered rock units are shown below the cross section. 
Which rock unit was formed most recently?

• A
• F
• L
• M

Lines CC and GG represent unconformities. The geologic ages of some of the lettered rock units are shown below the cross section. 
Why is there no contact metamorphism indicated between rock unit L and rock unit F?

• Conglomerate does not metamorphose.
• The intrusion was not hot enough to metamorphose rock unit F.
• The contact metamorphism within rock unit F eroded away.
•  Rock unit F was deposited after the intrusion of rock unit L.

Lines CC and GG represent unconformities. The geologic ages of some of the lettered rock units are shown below the cross section. 
The diagrams below represent three index fossils found in one of the rock units.
These fossils are most likely found in

Which inference about rock units D, E, and H can best be supported by evidence in the cross section?

• They contain mostly sand-sized sediment.
• They contain both land and marine fossils.
• They were altered by contact metamorphism
• They were deposited as horizontal layers and were later tilted.
