- mountains helped protect the ancient greece by making it difficult for foreigners to attack\
- mountains allowed them to grow grapes and olives which produced wine and olive oil
- they were separated by their rivers but were still able to do water trade
mean
average of the data set
Exosphere
the outermost region of the Earth's atmosphere air gets thinner and extremely cold, outer space
mode
# that appears most often in the data set
air pressure
a column of air that exerts a force on you and other objects
Explain what a city-state is and list its features
- a city state is an independent city with its own government and economic system
- shares culture, language, and religious beliefs
-it's formed in Greece
-has its own military
-its a walled city
median
middle of # in the data set
thermosphere
Earth's boundary with the exosphere and outer space. Radiation from the sun is absorbed by molecules but because they are so apart and cant transfer heat its very cold
name the five dynastys
xia
shang
zhou
qin
han
altitude
distance above sea level
Athens
- focused on their brains and their education
- men rule all aspects of life
- a society of growth
- building statues, philosphy and art
rhombus
opposite sides are parallel and opposite angels are equal
mesosphere
protects earth from most meteoroids because they burn up here due to friction when striking the gases in this layer its still quite cold
kinetic energy
it is energy that an object has when its in motion

-barley trade
- no growth
compatible
#'s/# that are easy to compute
stratosphere
contains most of the ozone absorbs ultraviolet light from sun, heats molecules in air. where jets fly . temps, increase here as you increase altitude. life we know wouldn't be possible without this layer
range
difference of the minim and maximum #
What mixture of gases is found in the atmosphere?
99% is nitrogen and oxygen and 1% of other gases
how did qin shi unify china
- legalism: ruled by fear
-Standarization: same $, weights, roads
- Built Great Wall of china to protect people
- ruled during warring kingdom kingdom ended
ratio
compare to #'s (is a fraction)
troposphere
where earths weather occurs, where we live. conditions are always changing its never consistant.almost all the earth carbon dioxide. water vapor, clouds, air pollution, and life forms are here
