A rock made out of shells and corals cemented together is called a limestone.
A rock is a naturally occurring solid substance composed of one or more minerals or mineraloids.
- Limestone is a sedimentary rock that is composed mainly of calcium carbonate (
) in the form of the mineral calcite.
- Limestone forms from the accumulation of shells, coral, and other debris that have been deposited on the bottom of bodies of water such as oceans, lakes, and rivers.
- Over time, the weight of the overlying sediment compacts and cements the shells and other debris together to form solid rock.
Therefore, a limestone is a rock formed by the cementation of shells and corals.

The three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.
What is the reaction of metal with water?
When metal reacts with water, hydrogen and metal hydroxide is produced.
Potassium is more reactive than lithium.
Alkali metals are also reactive with water.
The metal self ignites.
Thus, the three similarities are hydrogen is produces, metal floats and move around the water, and metal disappeared. The difference is potassium is more reactive than lithium.

THEY BOTH React violently with water
THEY Both: Give off heat
THEY Both: Give off light
Lithium will float on the water and become engulfed in flame and then die off, and Potassium will become engulfed in flames and then explode.
