8 what is the only entirely liquid layer of the earth?\na the upper mantle\nb the outer core\nc the inner core\nd the lower mantle
Answer
Brief Explanations:
The Earth's layers:
- The upper mantle is semi - solid (asthenosphere is partially molten but not entirely liquid).
- The outer core is in a liquid state due to high temperatures and pressure conditions that keep it molten (composed mainly of iron and nickel).
- The inner core is solid because of extremely high pressure despite high temperatures.
- The lower mantle is solid (with some degree of plasticity but not liquid).
Answer:
B. The outer core
