Answer:
Hilly flanks theory
Explanation:
HILLY FLANKS THEORY is the theory proposed by Robert Braidwood, arguing that agriculture arose in areas where the wild ancestors of domesticated wheat and barley grew, and resulted from human efforts to increase the productivity and stability of their food base.
He proposed and suggest in 1948, that agriculture began in the hilly flanks of the Taurus and Zagros mountains, where the climate was not drier, as Childe had believed, and that fertile land supported a variety of plants and animals amenable to domestication.
The first evidence was presented by Wegner when he hypothesized that all the continents once formed a single land mass called the Pangea before drifting apart. So, to fill in the blank, it would be that '<em /><em>neighboring continents [are] like jigsaw puzzle pieces</em>'
The five distinct layers of the atmosphere based on the changes in temperature and the elements are:
The troposphere: This is the first and lowest layer of the atmosphere of the Earth. Most weather activities takes place here
The stratosphere: The stratosphere is the second layer of the atmosphere of the Earth. Ozone layer is found in the stratosphere
The mesosphere: The mesosphere is directly above the stratosphere. In this layer of the atmosphere, temperature decreases with increasing altitude
The thermosphere: This layer of the atmosphere is above the mesosphere and below the exosphere.
The exosphere: This is the outermost layer of Earth's atmosphere
<h3>What is atmosphere?</h3>
Atmosphere can be defined as layers of gases which envelope a planet

The Second War brought complete destruction to that region. Entire cities were leveled by the germans and russians.<span>. If you go to Poland today, for example, what you see in Warsaw and Gdansk are copies. The "medieval" buildings are all or mostly reconstructions, from the rubble left behind by German and Soviet bombs and artillery. After that, the communists imposed central planning on top of a destroyed economic base. It's very hard to regenerate money from nothing, and most of what is produced in eastern Europe went into Warsaw Pact defenses and salaries and privileges for the communist party elite, to keep the system of authority in place. After the fall of communism, the post-Cold War governments inherited another kind of economic decay. They instituted "reform" plams to shock the economies into the free market, leaving in their wake massive unemployment and property.</span>
