Aliquid cooled down below a certain temperature becomes a

it becomes a solid because it will freeze

Hope This Helps!         Have A Nice Day!!

Explanation:

In a liquid, atoms are less strongly held together as compared to solids. Due to this the atoms are able to slide past each other.

But when liquids are cooled at a certain temperature then their atoms come closer to each other. As a result, they are held by strong forces due to which liquid phase changes into solid phase.

For example, water freezes at zero degree celsius.

Thus, we can conclude that a liquid cooled down below a certain temperature becomes a solid as it freezes.

4. Ancient sandstone beaches become buried deep beneath the Earth’s surface, where they are exposed to extreme heat and pressure.

Explanation:

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
