Answer:
d. warmer climate that followed the ice age made it easier to plant and raise crops.
Explanation:
Women discovered agriculture basically by accident. It is told that they would spread seeds and, once they returned to a place where seeds were spread and found out that new crops were growing. Combining that finding with the climate change (which provided longer growing seasons and drier land), and the fact that the populations were growing, the need of new sources of food, the new findings about the seeds and the new temperature all caused the transition.
Mid latitude zones are the regions of the Earth that lie between 23°26'22" and 66°33'39" north, and between 23°26'22" and 66°33'39" south. There are four types of midlatitude climates: mediterranean, humid subtropical, marine west coast and humid continental.
Some of the most significant characteristics of these regions are the winds. As they are located between the tropics and the polar circles, they get both cold and warm air masses, which causes fast-changing weather.
They also experience weather fronts, which is a boundary that separates two masses of different air. It can cause wind shifts and occasionally rain, thunderstorms or fog.
Finally, they can receive extratropical cyclones, causing anything from mild rain to blizzards and tornadoes.
