Mineral
Characteristics
Characteristics
All minerals are organic or inorganic?
Inorganic.
The internal arrangement of atoms or ions determines the shape of a crystal?
True. The internal arrangement of atoms or ions determines the shape of a crystal.
A silicate is a member of the mineral group that has silicon and hydrogen in its crystal structure?
False. A silicate is a member of the mineral group that has silicon and oxygen in its crystal structure.
There are over 40,000 minerals on earth?
False. There are 4,000 minerals on earth.
What is molten rock stored beneath the earth's surface is called?
Molten rock stored beneath the earth's surface is called magma.
Minerals can be a gas or vapor?
False. Minerals are a solid.
The vast majority of minerals are crystals?
True. The vast majority of minerals are crystals.
A nonsilicate contains silicon and oxygen?
False. A nonsilicate does not contain silicon and oxygen.
Of the 4,000 minerals on earth, how many are common?
There are 30 common minerals on earth.
When molten rock erupts on or near Earth's surface, what is is called?
Molten rock on or near the Earth's surface is called lava.
Minerals form a predictable crystal pattern?
True. Minerals form a predictable mineral pattern.
A repeating arrangement of atoms or ions in three directions is what makes a crystal a crystal?
True. Crystals form from an arrangement of atoms or ions that repeat in three directions.
The two main families of rock-forming minerals are the silicates and hydro-silicates?
False. The two main families of rock-forming minerals are the silicates and nonsilicates.
Of the 30 common minerals on earth, how many are rock forming.
There are ten rock-forming minerals.
What is the word for when solids crystalize out of the water and form minerals?
When solids crystalize out of the water and form minerals they evaporate.
All minerals are naturally occurring?
True. All minerals are naturally occurring.
Why doesn't glass exhibit crystalline form?
Glass cools quickly from a molten state, and its atoms don't have time to form an orderly structure.
All minerals form through a process called crystallization?
True. All minerals form through a process called crystalization.
To be a mineral, does a solid have to have a crystal form?
Yes. To be a mineral a solid has to have a crystal form.
How does gold form?
Gold crystallization from a hot-solution and filled in cracks between rocks.
Minerals do not have an orderly arrangement of atoms or ions?
False. All minerals have an orderly arrangement of atoms or ions.
How is halite crystal different from a piece of glass that is commonly called a crystal?
A halite crystal has an orderly, three-dimensional pattern that repeats. A piece of glass has a random pattern, not an orderly, repeating pattern.
Is feldspar the most common silicate mineral in Earth's crust?
True. Feldspar is the most common silicate mineral in Earth's crust.
Minerals are inorganic, but can they form as a result of organic processes?
Yes. Minerals can form as a result of organic processes.
Small crystals result from lava cooling quickly or slowly?
Small crystals form from lava cooling quickly.
