Answer:
The answer is B
Explanation:
The absorption happens when photons from light hit atoms and molecules, and they vibrate because of that specific interaction. Then the heat ejects from the object in the format of thermal energy.
Explanation:
Continental rifts and mid-ocean ridges are both features of a divergent plate margin.
In both cases plates are moving away from one another. Therefore they are creating new land masses.
- A continental drift like the east African rift valley is where a continent begins to pull apart or diverges.
- A mid-ocean ridge is divergent margin in the ocean.
They are different in that, continental rift occurs within the continental plate that are on land.
But:
Mid-ocean ridges are in the oceanic crust in the ocean . They form the largest physiographic structure on the earth surface called the mid-ocean ridge.
