Answer:
a) The rise of farming and domestication of animals.
Explanation:
An ice age is a long period of reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet.
What caused the end of the Ice Age?
The variation of sunlight reaching Earth is one cause of ice ages. ... When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.
Developments caused in part by the end of the last ice age and its resulting climate change around 9000BCE:
Around 10,000 years ago, the latest ice age came to an end. Sea levels rose as the ice sheets melted, and Britain became separated from the European mainland shortly
The introduction of farming, when people learned how to produce rather than acquire their food, is widely regarded as one of the biggest changes in human history.
This change happened at various times in several different places around the world. The concept of farming that reached Britain between about 5000 BC and 4500 BC had spread across Europe from origins in Syria and Iraq between about 11000 BC and 9000 BC.
Traditionally the arrival of farming is seen as a major and rapid change sometimes called the 'Neolithic revolution'
