I think you are looking for a work for it - and this word is "megalopolis"
Some examples of a megalopolis are:
A Taiheyo belt in Japan (with Tokio and Osaka)
Northeast Megalopolis with New York and Boston
Yangze River Delta in China
A. Ida B. Wells
He urged African Americans to protest by refusing to ride street-cards, to stop buying from white owned stores and only buy from black owned stores
Answer:
either the first or the third one
Explanation:
A process that uses observation and experimentation to gain knowledge is called science. The organized set of investigation procedures which is used in science is called a scientific method. Applied science on the other hand is referred to as technology.
Explanation: Since air has mass, it also has weight. The pressure of air at a given place is defined as a force exerted in all directions by virtue of the weight of all the air above it.
The weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere is called the atmospheric pressure. The atmospheric pressure is expressed in various units.
Measurement of Air Pressure
Atmospheric pressure is the weight of the column of air at any given place and time. It is measured by means of an instrument called barometer.
The units used by meteorologists for this purpose are called millibars (mb).
One millibar is equal to the force of one gram on a square centimeter. A pressure of 1000 millibars is equal to the weight of 1.053 kilograms per square centimeter.
In other words, it will be equal to the weight of a column of mercury 75 cm high.
The normal pressure at sea level is taken to be about 76 centimeters (1013.25 millibars).
Vertical Variation of Pressure
In the lower atmosphere the pressure decreases rapidly with height.
