The neolithic era began when some groups of humans gave up their pneumatic hunter gatherer lifestyle completely to the beginning farming. It may have taken humans hundreds or even thousands of years to transition fully from the lifestyle of subsisting on wild plants to keeping small gardens and later trending large crab feilds.
The Underground Railroad was the name of the escape routes used by slaves to escape the South and flee to the North. It was a network of special routes and safe houses that were used by both slaves and abolitionists who were sympathetic to their cause of escaping slavery. It started in the late 1700's and ended after the abolition of slavery. Canada was a popular destination, as slavery was prohibited their and had a longer border for easier access.
Tectonic Forces
Rocks are under stress when they are subjected to a force at depth. When the rocks are exposed at the surface after uplift and erosion, the effects of the stress can be studied. Stressed rocks show varying degrees of strain—the change in the volume and/or shape of the rock because of that stress. For example, a volcanic agglomerate may be compacted and its pyroclastic fragments stretched (strained) in response to a tectonic stress, such as compression.
As the birthplace of Muhammad and the site of Muhammad's first revelation of the Quran(specifically, a cave 3 km (2 mi) from Mecca),Mecca is regarded as the holiest city in the religionof Islamand a pilgrimage to it known as the Hajjis obligatory for all able Muslims. Mecca is home to the Kaaba, by majority description Islam's holiest site, as well as being the direction of Muslim prayer. Mecca was long ruled by Muhammad's descendants, the sharifs, acting either as independent rulers or as vassals to larger polities. It was conquered by Ibn Saud in 1925. In its modern period, Mecca has seen tremendous expansion in size and infrastructure, home to structures such as the Abraj Al Bait, also known as the Makkah Royal Clock Tower Hotel, the world's fourth tallest building and the building with the third largest amount of floor area. During this expansion, Mecca has lost some historical structures and archaeological sites, such as the Ajyad Fortress.
Today, more than 15 million Muslims visit Mecca annually, including several million during the few days of the Hajj.As a result, Mecca has become one of the most cosmopolitan cities in the Muslim world,
even though non-Muslims are prohibited from entering the city.
Expansionary and contractionary policies can be used to encourage or discourage economic growth. Expansionary policies generally lower taxes and give consumers and producers additional money, which encourages spending and growth. This is done when unemployment is high. On the other hand, contractionary policies generally raise taxes, which can give consumers and producers less to spend. This can cause less economic growth, but is necessary when the economy is growing too quickly and inflation is rising.
