Final answer:
The statement is false - the greatest mountain ranges on Earth lie on land, not on the ocean bottoms.
Step-by-step explanation:
The statement that the greatest mountain ranges on Earth lie on the ocean bottoms and extend more than 65,000 km is False.
The greatest mountain ranges on Earth are actually found on land, such as the Himalayas and the Andes. These mountain ranges are formed by the collision of tectonic plates, which push the crust upwards and form tall mountain ranges. On the ocean floor, there are underwater mountain ranges known as mid-ocean ridges, but they do not extend more than 65,000 km.
Therefore, the statement is not factually accurate.
