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:
loss of volatiles to the atmosphere
Explanation:
volatiles are the group of chemical elements and chemical compounds with low boiling points that are associated with a planet's or moon's crust or atmosphere. Examples include nitrogen, water, carbon dioxide, ammonia, hydrogen, etc.
Volatiles were accreted throughout the Earth’s formation, but Earth’s early accretion history was volatile poor.
Answer:
Air molecules scatter blue light more efficiently than other colors.
Explanation:
The sunlight has many colors and each of them has a different wavelenght. The color blue has shorter wavelengths and higher frequencies than the other colors. So, as sunlight goes through the air, the blue part causes charged particles to oscillate faster than the red part does and it is scattered more efficiently than the other colors and that's the reason for the sky to be blue.
