100
Name the sphere or system of earth that controls water.
hydrosphere
100
What layer of the earth do humans live on?
Crust
100
Contains all frozen water on Earth.
cryosphere
100
Describe the mesosphere
The mesosphere is the middle structural layer and it also behaves as a plastic solid which means that even under intense pressure, the rock flows.
100
Why is it necessary to use more than one property for mineral identification?
The more properties that you use to identify a mineral, the more you can narrow the similarities , thus identifying the mineral
200
Name the system that controls rocks/soil
geosphere
200
What layer of the earth is the largest layer
mantle
200
atmosphere, hydrosphere, biosphere
200
What layer of the earth does magma come from
mantle
200
There are three major rock types
sedimentary, metamorphic, and igneous.
300
The crust and the upper mantle make up which mechanical/structural layer of Earth?
lithosphere
300
Magma is teh molten rock inside of the earth. What is it called when it flows outside of the earth?
lava
300
The structural/mechanical layers of Earth are based on ______
based on how each layer behaves which is the result of the temperature and pressure that occur in/near each layer.
300
Describe the outer core and inner core
The outer core is the second innermost structural layer and it behaves as a liquid.
The inner core is the innermost structural layer and it behaves as a rigid solid
300
400
The biosphere contains what system?
living things
400
The core of the earth is made up of what two melted metals?
iron and nickel
400
Describe the lithosphere
outermost structural layer and it behaves as a rigid solid
400
What is a mineral?
A mineral is a naturally occurring, inorganic solid with definite chemical composition and an orderly arrangement of atoms or ions.

500
What are the four spheres or systems of our earth?
biosphere, hydrosphere, geosphere, atmosphere
500
Name the four layers of our earth
crust, mantle, inner core, outer core
500
describe the asthenosphere
second-outermost structural layer and it behaves as a plastic solid which means that even under intense pressure, the rock flows.
500
What properties can be used to identify minerals?
physical properties such as
Density, the ratio of mass to volume for a substanceHardness, a measure of how easily a mineral can be scratched
Streak, the color of a mineral’s powder
Luster, the way a mineral’s surface reflects light
Fracture or cleavage, how a mineral breaks with rough, uneven surfaces or smooth, flat surfaces (respectively)
