Luster is how a mineral reflects light. The terms metallic and nonmetallic describe the basic types of luster.

What term describes the light reflecting and transmission characteristics of a mineral?

The strong tendency of certain minerals to break along smooth, parallel planes is known as ________. Which of the following describes the light reflecting and transmission characteristics of a mineral? luster. Hornblende and the other amphiboles have what type of silicate structure?

Which of the following physical properties of minerals describes the tendency of a mineral to break along parallel planes?

Crystals often contain planes of atoms along which the bonding between the atoms is weaker than along other planes. In such a case, if the mineral is struck with a hard object, it will tend to break along these planes. This property of breaking along specific planes is termed cleavage.

Which of the following statements best defines a mineral and a rock?

Which of the following best defines a mineral and a rock? In a mineral, the constituent atoms are bonded in a regular, repetitive, internal structure; a rock is a lithified or consolidated aggregate of different mineral grains.

What are 4 characteristics of a mineral?

Explanation:
are solid.are inorganic.are naturally occurring.have a definite chemical composition and crystalline structure.

What are the characteristics of mineral resources?

The following are the main characteristics of mineral resources:
Mineral resources are nonrenewable resources. Mineral resources have a definite chemical composition. The minerals whatever the type cannot be used directly. Minerals come from inorganic processes.

What characteristics of a mineral refers to resistance to abrasion?

What characteristics of a mineral refers to resistance to abrasion? Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs.

Which of the following best describes the term cleavage quizlet?

Which of the following best describes the term cleavage? Cleavage is the splitting of minerals along natural planes of weakness.

What is the tenacity of a mineral and how can it be described?

Tenacity is the resistance of a mineral to breaking, and tenacity can be characterized as brittle, malleable, sectile and elastic. Hardness is the ability of a mineral to resist scratching, and the Mohs Scale provides a relative ranking of hardness for ten different minerals.

What physical property refers to the tendency of some minerals to break along flat surfaces?

Cleavage. is the tendency of a mineral to break along flat surfaces. The way in which a mineral breaks depends on how its atoms are bonded, or joined together. In a mineral that displays cleavage, the bonds of the crystal structure are weaker in the directions in which the mineral breaks.

What are these minerals physical properties chemical properties?

Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.

What determines the physical and chemical properties of a mineral?

The physical properties of minerals are determined by the atomic structure and crystal chemistry of the minerals. The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).

Which of the following best defines a mineral *?

A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.

How does mineral cleavage differ from mineral fracture?

Cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces.

Which of the following rocks is composed mainly of Ferromagnesian minerals?

The altramafic rocks consist of almost entirely ferromagnesian minerals.

What are the 5 characteristics that make a mineral a mineral?

A mineral has 5 characteristics, naturally occurring, solid, inorganic, crystalline structure, and the same chemical composition throughout So repeat after me A mineral is Naturally occurring-naturally occurring Inorganic solid-inorganic solid Crystalline structure The same chemical composition throughout.

What is the defining characteristic of a mineral?

Minerals always occur in nature, they are solid and are inorganic. They have a crystal structure and each mineral has a unique chemical composition.

What makes a mineral a mineral?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties.
