which material rises from cracks in oceanic crust?\n○ dense crust\n○ molten rock\n○ continental crust\n○ pillow - shaped rocks
Answer
Brief Explanations:
To solve this, we analyze each option:
- "dense crust": Oceanic crust is dense, but it doesn't rise from cracks as a material rising.
- "molten rock": At mid - ocean ridges (cracks in oceanic crust), molten rock (magma) from the mantle rises to form new oceanic crust.
- "continental crust": Continental crust is thicker and less dense, and it doesn't rise from oceanic crust cracks.
- "pillow - shaped rocks": These are formed when molten rock cools underwater, not the material rising from cracks.
Answer:
B. molten rock
