Sun is the main source of energy
Answer:The answer is B
Explanation:
A generator produces electricity. Energy enters the system (generator) as kinetic energy. It is converted into electrical energy, which can run electrical appliances. Some energy is always wasted as heat and sound. Therefore, Choice B is the best answer.
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.
