Definition: A type of mineral that is red to brownish-red and belongs to the garnet group, often containing manganese and aluminum.

Example: The geologist discovered a beautiful piece of spessartite while exploring the cave.

Definition: A mineral that is mainly made of zinc sulfide and is the most important source of zinc, often found in yellow-brown or black crystals.

Example: Sphalerite is commonly mined for its zinc content.

Definition: A mineral that contains calcium, titanium, and silicon, often found in small brown or yellow crystals, and sometimes used as a gemstone.

Example: The jeweler showed me a beautiful ring with a sphene stone.

Definition: Having a shape that resembles a wedge, typically with a narrow end and a wider end.

Example: The sphenic design of the building allowed for better aerodynamics.

Definition: The quality or state of being shaped like a sphere.

Example: The sphericity of the planet affects its gravitational pull.

Definition: The study of shapes and figures that are spherical in nature, often involving geometry and trigonometry related to spheres.

Example: In advanced mathematics, spherics is essential for understanding the properties of spherical shapes.

Definition: The activity of rolling or moving inside a large, round, inflatable ball, often for entertainment or sport.

Example: Sphering is a popular activity at adventure parks where people can roll down hills inside a giant ball.

Definition: An object that is shaped like a sphere but is not perfectly round, often resembling an ellipsoid.

Example: The planet Earth is often described as a spheroid due to its slightly flattened shape at the poles.

Definition: Having a shape that is similar to a sphere, being roughly round or ball-like.

Example: The planet has a spheroidal shape, making it appear almost like a perfect ball in space.

Definition: A shape that is similar to a sphere but not perfectly round, often used to describe objects that are slightly flattened or elongated.

Example: The planet is not a perfect sphere; it has a spheroidal shape due to its rotation.

Definition: A tool used to measure how curved a surface is, such as that of a sphere or cylinder.

Example: The engineer used a spherometer to check the curvature of the lens.
