Definition: A process where the chemical makeup of a rock changes due to interaction with fluids, leading to the replacement of one mineral with another without melting.

Example: Metasomatism can significantly alter the properties of rocks in geological formations.

Definition: A condition in which a system is not in its most stable state but can remain in that state for a long time before changing.

Example: The chemical reaction reached a state of metastability, allowing it to persist longer than expected.

Definition: Referring to a state of a system that is not completely stable but lasts longer than other unstable states, often seen in chemistry or physics.

Example: The metastable state of the solution allowed it to remain in that form for a longer period than expected.

Definition: In a state that is stable but not in the lowest energy state, often used in scientific contexts.

Example: The system can exist metastably for a long time before transitioning to a more stable state.

Definition: The process where cancer cells spread from one part of the body to another, forming new tumors.

Example: The doctor explained that the metastasis of the cancer made treatment more complicated.

Definition: To spread or grow in a harmful way, especially in reference to cancer cells moving from one part of the body to another.

Example: The cancer began to metastasize, affecting other organs in the body.

Definition: Related to the spread of cancer from one part of the body to another.

Example: The doctor explained that the tumor was metastatic, meaning it had spread to other organs.

Definition: Relating to the part of the foot between the ankle and the toes, specifically the five long bones that form the front part of the foot.

Example: The doctor explained that the pain was due to a metatarsal injury.

Definition: A type of bone located in the middle part of the foot, connecting the toes to the ankle.

Example: The doctor explained that the pain was due to a fracture in one of the metatarsals.

Definition: Relating to the metathorax, which is the third segment of the thorax in insects, located behind the mesothorax.

Example: The metathoracic region of the insect is crucial for its flight mechanics.

Definition: The back part of an insect's body that is located behind the middle section, which supports the last pair of legs and wings.

Example: The butterfly's metathorax is crucial for its flight stability.
