Identifying Minerals
100
78% of the atmosphere
What is nitrogen

Scientists have identified four main layers of the atmosphere.
How many layers are in the atmosphere.
100
In both hemispheres, the winds that flow toward the equator between 30 and 0 degrees latitude
What are trade winds?
100
To determine whether a substance is a mineral or a non-mineral.
What are four basic questions.
100
They examine, analyze, and classify minerals.
What is a mineralogists?
200
As water evaporates from oceans, lakes, streams, and soil it enters air as
What is water vapor
200
The layer where nearly all weather occurs.
What is the troposphere?
200
It deflects a moving object along a path that depends on speed, latitude, and the direction of the object.
What is the Coriolis effect?
200
Approximately 4% of the Earth's crust is made up of.
What are nonsilicate minerals
200
The strength of the bonds between the atoms that make up a mineral's internal structure.
What determines the hardness of a mineral
300
It keeps 99% of the total mass of the atmosphere withing 32 km of Earth's surface.
What is gravity
300
The upper boundary has an average temperature of -90 degrees C.
What is the mesophere
300
Each hemisphere contains three looping patterns of flow.
What are convection cells?
300
Most single chain silicate minerals
What are pyroxenes
300
A more reliable clue to the identity of a mineral is the color of the mineral in powered form
What is the mineral's streak.
400
The atmosphere contains tiny solid and liquid particles
What is particulates
400
The layering of warm air on top of cool air.
What is temperature inversion?
400
The heating of the lower atmosphere is primarily the result of the distribution of heat through the troposphere.
What is convection?
400
These include quartz, orthoclase, plagioclase, biotite, calcite, and gypsum.
What are rock-forming minerals
400
It takes place because light rays are split into two parts.
What is double refraction?
500
The most commonly used barometer today
What is aneroid barometer
500
The fraction of solar radiation that is reflected by a particular surface.
What is albedo?
500
they are in subtropical high-pressure zones that also have weak surface winds
What are horse latitudes?
500
They form when shared oxygen atoms join the tetrahedra to form three-, four, or six sided rings.
What is a ring silicate?
500
Depends on the kinds of atoms that the mineral has and on how closely the atoms are packed.
