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.
Answer:
B. Aerobic bottom water
D. High organic productivity in the overlying oxygen rich water
Explanation:
A Shale is a sedimentary rock usually formed from silt and clay-size mineral. There are different colors of Shale. The Black Shale is formed under anaerobic conditions. This means that oxygen is deficient in the water where the Shale forms.
A little amount of organic materials is required for the formation of Black Shale and because Black Shale is formed in an environment lacking oxygen, an oxygen-rich water would not be necessary for its growth. Sediments are necessary in the formation of Black Shale.
