The word from the list that best fits the definition: Hardens to form new rock at mid ocean ridges. Is: Magma
Explanation:
Magma is the melted material that comes out of volcanoes weather if they are under the sea or on the surface of the earth's crust. In both cases, it will harden to form rocks. Nevertheless, it will only form new rock at mid-ocean ridges if it is close or under the sea. Magma travels in the water to harden to solidify. If it is outside the sea it will come from erupting crust volcanos and solidify after the water lowered its temperature. This is a very common phenomenon in Hawaii.
The molecule is formed from glucose, which fits together nicely and becomes sturdy. It relates to the function of the cellulose model because it aids in strength and structural support.
