Definition: Describing something that has three openings or compartments, often used in reference to certain types of shells or mechanical devices.

Example: The trivalve design of the shell allows for better water flow.

Definition: Having a shape similar to a wheel, often used to describe certain biological structures.

Example: The trochal structure of the rotifer helps it to move through water efficiently.

Definition: A group of small birds known for their ability to hover in mid-air and their vibrant colors, commonly referred to as hummingbirds.

Example: The trochili are known for their incredible flying skills and beautiful plumage.

Definition: A part of the body that looks like a pulley, found in the arm where the upper arm bone connects to the forearm bone.

Example: The trochlea of the humerus allows for smooth movement of the elbow joint.

Definition: Describing something that can rotate around a central point or axis.

Example: The trochoid mechanism allows for smooth rotation in the machine.

Definition: A specific type of curve created by a point on a circle as it rolls along a straight line.

Example: The path of the toy car followed a trochoid as it rolled down the ramp.

Definition: Relating to a specific type of curve known as a trochoid, which is formed by the path traced by a point on a circle as it rolls along a straight line.

Example: The engineer designed a trochoidal gear system to improve efficiency.

Definition: A type of mineral that is a form of pyrrhotite, commonly found in meteorites and lunar soil, and does not contain much ferrous iron.

Example: Troilite is often studied by scientists to understand the composition of meteorites.

Definition: A cylindrical device that rotates to separate materials, often used in mining to sort rocks and ores.

Example: The workers used a trommel to sift through the dirt and find valuable minerals.

Definition: A natural mineral that is gray or white, made of sodium carbonate and used for producing sodium compounds.

Example: Trona is often mined for its sodium content, which is important in various industrial processes.

Definition: A white, crystalline substance that is toxic and is derived mainly from another compound called atropine.

Example: Tropine is used in some chemical research due to its unique properties.
