The three Intermediate Periods in the history of ancient Egypt mark the
collapse of Egyptian governments (the Old, Middle, and then New Kingdom)
caused by natural cycles of drought.
true or false Answer - true
The Intermediate Periods did follow and mark the collapse of the Kingdoms.
They were caused by the instability and famine from natural drought cycles.
What are the Milankovitch cycles? Answer - The cycle of changes in Earth's
wobble, tilt, and orbit
The Milankovitch cycles are changes in Earth's wobble, tilt, and orbit that occur
on a schedule of 20,000 to 100,000 years. The Milankovitch cycles affect global
climate by changing the distribution of solar radiation and can lead to drought
periods in Egypt. The annual cycle of rainfall in Ethiopia is called the monsoons.
Why has the Nile River remained in the same place for 30 million years?
Answer - A magma hot spot in Earth's interior creates a slope from Ethiopia to
the Mediterranean Sea.
Rivers tend to meander and change their path frequently, even annually. The
Nile River is unique because it has remained in roughly the same location for 30
million years. A persistent hot spot under Ethiopia which leads to rising magma
pushes up the Earth's crust creating the Ethiopian mountains. The Nile follows
,the slope from the mountains to the Mediterranean Sea. Although ancient
Egyptians did create dams and canals which controlled the flow of the river,
they did not alter the overall path of the river from Ethiopia to the
Mediterranean in the Nile River Valley.
The south-easterly winds during the summer monsoon bring moist air from the
ocean towards East Africa, thus causing heavy rainfall in Ethiopia from June to
September.
true or false Answer - true
Monsoons, which occur all over the world, are characterized by the switching
of wind patterns in different seasons. In this region, the south-easterly winds
(i.e. coming from the south-east) during the summer monsoon bring moist air
from the ocean towards East Africa, thus causing heavy rainfall in Ethiopia from
June to September.
Over 80% of the water in the Nile River comes from the White Nile River
originating at Lake Victoria 3,000 miles away.
true or false Answer - false
Contrary to what was first believed, over 80% of the water in the Nile River
actually comes from the Blue Nile River tributary originating at Lake Tana 3,000
miles away.
Ancient Egyptian jobs and religion were based around the seasons. Match the
ancient Egyptian seasons with the modern calendar months.
Agriculture Season (Beret)
, Harvest Season (Shomu)
Flood Season (Akht) Answer - Agriculture Season (Beret): January-April
Harvest Season (Shomu): June-August
Flood Season (Akht): September-December
Ancient Egyptian farmers experienced the same soil salinization problems as
the Sumerians
true or false Answer - false
Unlike the Sumerians, ancient Egyptians did not have the same soil salinization
problems (a toxic build up of salts in the topsoil). This is because Egyptian fields
were elevated above the river and were seasonally flooded in the summer and
fall. When the water receded into the soil, there was no clay barrier so the salts
were pulled away from the topsoil with the water, but the nutrient-rich fertile
silt was left at the surface.
The African Humid Period, or Green Sahara, ~11,000 to 5,000 years ago, was an
isolated event that occurred only once in the past 8 million years.
true or false Answer - false
Green Sahara events have occurred 230 times in the past 8 million years caused
by changes in the planet's wobble, tilt, and orbit that impact monsoons and
climate.
What evidence is there for the Green Sahara?
A mega lake in the Sahara larger than the great lakes combined
