Answer:ccording to Arab oral tradition, Islam first came to Africa with Muslim refugees fleeing persecution in the Arab peninsula. This was followed by a military invasion, some seven years after the death of the prophet Mohammed in 639, under the command of the Muslim Arab General, Amr ibn al-Asi. It quickly spread West from Alexandria in North Africa (the Maghreb), reducing the Christians to pockets in Egypt, Nubia and Ethiopia.Islam came to root along the East African coast some time in the 8th century, as part of a continuing dialogue between the people on the East coast and traders from the Persian Gulf and Oman. Like early Christianity, Islam was monotheistic, that is, Muslims worship only one God.Islam was a modernising influence, imposing a consistent order among different societies, strengthening powers of government and breaking down ethnic loyalties.Unlike Christianity, Islam tolerated traditional values, allowing a man to have more than one wife. For many, this made conversion to Islam easier and less upsetting than conversion to Christianity.In the early centuries of its existence, Islam in Africa had a dynamic and turbulent history, with reforming movements and dynasties clashing and succeeding each other. Gaining power depended on securing trade routes into gold-producing areas in Sub-Saharan Africa. Islamic rulers expanded north as well as south. In the last quarter of the 11th century, Islam dominated the Mediterranean world.In the 14th century the Black Death came from Europe and seriously undermined the social and economic life of North Africa, or the Maghreb, as it is known. However Islam remained the dominant religion.From the 16th to the 19th century, much of the Maghreb was under Ottoman rule. By the 1880's, Islam had taken root in one third of the continent.All dates are given according to the western calendar but can be converted online.

Can the zodiac move through the constellation
Answer:
The ecliptic forms the center of the zodiac, a celestial belt about 20° wide in latitude through which the Sun, Moon, and planets always appear to move. Traditionally, this region is divided into 12 signs of 30° longitude, each of which approximates the Sun's motion in one month.
Explanation:
The sun's motion through the constellations
Its motion is entirely an illusion, caused by Earth's own motion around our star. Over the course of a year, the sun appears to be in front of, or “in”, different constellations.

Ingrid tropical cyclones sapphire Simpson and Beaufort scales
Tropical Cyclone Ingrid occurred in northern Australia in 2005 and reached Category 4 on the Saffir-Simpson wind scale.
What is the difference between the Saffir-Simpson and Beaufort scale?The Beufort scale was developed to describe winds that are below the strength of a hurricane. The Saffir-Simpson scale measures winds that exceed the intensities of tropical storms.
Therefore, the Saffir-Simpson scale is used to measure the intensity of a hurricane's winds in five categories, whose category 4, which Hurricane Ingrid reached, can reach winds of up to 251 km/h.

Answer:
hope this helps u
Explanation:
A drainage basin form certain patterns which depends on the kind of slope of land, the underlying rock structure and climatic conditions of the area. The main patterns are dendritic, trellis, rectangular, and radial patterns.
What is the relationship between climate change and the regularity of agricultural drought
Answer:How climate change contributes to drought: Warmer temperatures enhance evaporation, which reduces surface water and dries out soils and vegetation. This makes periods with low precipitation drier than they would be in cooler conditions.

Answer:answer down below
Explanation:
The main effects of revolution are cycle of seasons, apparent migration of the Sun, and temperature zones. Seasons are caused due to combined effect of revolution of the earth and the tilt of the earth's axis. Seasons of one hemisphere are opposite to that of the other hemisphere.
How does lattitude effects climate of a place?
Answer:
Latitude is a fundamental control on every climate. It affects temperature by influencing the seasonal range in solar intensity. It influences precipitation in as much as evaporation is temperature dependent. How does location affect climate? The distance from the equator affects the climate of a place.

a. What type of sedimentary environment is this? Specify how you came to this conclusion.
b. If the sediments you see today lithifies, what type of sedimentary rock would you expect to be most abundant in this area and how mature is this rock type? Specify how you came to this conclusion
The sedimentary environment referred to is of the glacial continental type and if it is lithified, the most abundant type of rock is expected to be deltritic rock.
What is a sedimentary environment?Sedimentary environments are areas of the earth's surface, where sediments can accumulate. Sedimentary environments are classified as continental, marine or transitional. In these areas, the sediments are deposited, beginning the lithification or diagenesis, by which they are transformed into sedimentary rocks.
What are detrilitic rocks?Detrital rocks are a group of rocks characterized by the existence of fragments of pre-existing rocks (clasts) surrounded by a matrix, which can be of two types of clay (if it is clay) and micritic (precipitation of carbonates).

Answer:
y= - -6v + 6/5 (the fraction is negative and the 6 is too)
Explanation:
switch sides
-2(-5y+2)=-4(-v+4)+8v
divide both sides by -2
-2(-5y+2)= - 4(-v+4)/-2 (fraction is negative not the four)+8v/-2
Simplify
-5y+2=-2(3v-4)
Subtract 2 from both sides

-5y=-6v+6
Divide both sides by -5
-5y/-5= -6v/-5+ 6/-5

was the earthquake in Orkney 2014 related to San Andreas fault
Answer:
yes
Explanation:
because i said so
No, the earthquake in Orkney in 2014 was not related to the San Andreas Fault.
The San Andreas Fault is a major geological feature located in California, USA, known for its high seismic activity due to the tectonic plate movement. Orkney, on the other hand, is an archipelago located in Scotland, far away from the San Andreas Fault.
The earthquake in Orkney was likely caused by regional geological processes unrelated to the San Andreas Fault, such as local fault lines or stress accumulation in the Earth's crust in that specific region.

Importance of River Capture on Ecosystem
Answer:
River basins are dynamic environments that are always changing and reorganizing under geologic forces. New research investigates how this shape shifting influences aquatic speciation and extinction.
The evolution of organisms and of their environments is inherently linked. Although the understanding that the gene pool is dynamic has shaped much of our understanding of modern biology, it’s easy to forget that environments are also in flux.
Research has shown that geologically active areas of the planet, especially those with rugged topography, may generate more species diversity. Stokes and Perron investigate the consequences of changes in topography for aquatic organisms and their habitats.
Drainage basins and river paths are constantly changing because of myriad natural phenomena, including tectonic activity, erosion, damming, and glacier retreat. These processes sometimes lead to abrupt alterations of river paths known as river captures. In the new study, the authors create and combine two models—one that describes macroevolutionary processes of speciation, extinction, and dispersal, and another that simulates river basin changes over time—to investigate how river capture influences the evolution of aquatic organisms.
The results indicate that river capture leads to transient increases in species richness: When the path of a river changes, organisms in the captured regions are introduced into new drainage basins and may become genetically isolated from populations with which they previously could have bred. Over time, these separated populations may diverge sufficiently to become new species.
The authors’ model also shows that both speciation and extinction events are more likely in river basins undergoing reorganization but that the speciation rate often outpaces the extinction rate, leading to higher diversification overall. When river capture events are frequent and organisms typically disperse and speciate slowly, biodiversity increases. Conversely, in cases where a drainage divide is changing but river capture rates are low, biodiversity drops.
