Enzymes lower the activation energy for a chemical reaction to proceed.

The statement is true since one of the main functions of the enzyme is to lower the activation energy so that a chemical reaction to proceed.

Explanation:

Enzymes are specialized protein molecules that contribute to faster chemical reactions. One of the functional characteristics of an enzyme is that it reduces the activation energy for a reaction to occur.

Activation energy is the amount of net energy required for a reaction to occur. By lowering the activation energy, a reaction occurs faster, which is achieved with a biocatalyst such as enzyme.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
