Answer:
D. Seafloor bedrock is younger near the ridge and older farther away.
Explanation:
In a divergence boundary oceanic plates or continental plates move apart. The plates moves apart causing an uprising of molten magma to form a new crust. The divergent movement of plate is very prevalent in the oceanic plates.
The plates in the oceanic crust moves apart due to the up welling of aesthenosphere materials . These aesthenosphere materials(molten magma) are introduce to the ocean floor through the mid oceanic ridge . As this materials are introduced through cracks and fissures, the plates continue to drift apart. The molten magma later solidified to form a new crust closer to the oceanic ridge. This is why sea floor bedrock closer to the ridge is younger as new rocks are formed here. But as one move farther away from the ridge the rocks become older. This phenomenon provide ample evidence that the seafloor is spreading. The older rocks found father away from the ridge proves the seafloor has been spreading given way for new rocks closer to the ridge.
The answer is false. I took the quiz for history, 3.04 8th grade. If you look at the map that was attached in the lesson with the color key, New-Orleans-Jacksonville is a urban area. Don't believe the "verified" answer! They're wrong.

Answer:
The electromagnetic radiation per-unit- area increase by 42.65 times.
Explanation:
The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,
P ∝ T⁴
For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:
T₀ = 900 K
T₁ = 2300 K
So,
<u>P₁ = 42.65 P₀</u>
<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>

It would be phytoplankton.
