| Question Walther’s law states: The
vertical succession of preserved sedimentary rocks at depth
can be explained through the lateral (horizontal) movement
of different depositional sedimentary environments. In order
for this law to make complete intuitive sense, which of the
following processes must be occurring? |
| Answer |
| |
a) Uplift of the sedimentary environment
|
|
|
b) Subsidence of the sedimentary environment
|
| |
c) Either A or B
|
| |
d) Elevated mountain building areas
