Answer:
Layer D
Explanation:
The rock layer with remains of organisms least similar to present day form can be found in Layer D.
Since layer D is the oldest layer, it will contain the oldest fossil in the undisturbed sequence.
This is because of the principle of fossils and fauna succession.
The principle states that "fossils and fauna succeed on another in a definite order".
- Therefore, the oldest rock layer should contain the oldest fossil which is layer D.
- Layer A is the youngest layer and its fossils will be very similar to those of present day.
- So, the older a rock layer, the more farther it will be in resemblance to present day organisms.
Option D which denotes layer D is the right choice.
I belive that the answer is A
To explain the geyser and hot spring that are formed in Yellow Stone National Park. Base on my research i came up with this explanation, First this park is well known for their natural wildlife habitat and most of all its geothermal features specially the Geysers and hot spring so it means the park has and active volcanic activity inside that allows the ground to form such features
Normal fault - a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

thrust fault - a dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, such as regions where one plate is being subducted under another as in Japan. When the dip angle is shallow, a reverse fault is often described as a thrust fault.

strike-slip fault - a fault on which the two blocks slide past one another. The San Andreas Fault is an example of a right lateral fault.
Strike-slip Fault Animation
A left-lateral strike-slip fault is one on which the displacement of the far block is to the left when viewed from either side.
A right-lateral strike-slip fault is one on which the displacement of the far block is to the right when viewed from either side.
