1) Arab traders brought Islam to North Africa - Started in the 7th century.
2) European trading posts; slave trade - The transatlantic slave trade began in the 15th century.
3) Scramble for Africa - Was the period of occupation, division, and colonization of African territory by European powers, which happened between 1881 and 1914.
4) European colonies established by Berlin conference - The Berlin Conference of 1884–1885, also known as the Congo Conference or West Africa Conference regulated European colonization and trade in Africa, it was seen as the formalization of the Scramble for Africa that had started earlier in 1881.
5) African nations gained independence - There has been some controversies about the first African country to gain independence, Egypt was the first in 1922, however, it was not considered as an African nation at that time, or lets say, some Egyptians did not accept that they were Africans, having said that, we can say Africa started gaining independence from 1922-1990 to when Namibia finally gained independence from the white minority apartheid government of South Africa, however, if we are talking about independence from European colonization, it is the Seychelles which got her independence from France on June 27th, 1977.
The process of bedding in sedimentary rock is defined by all of the characteristics listed. Thus, sedimentary rocks bedding can be defined by:
- Erosion
- Sediment size
- Thickness
- Color etc
<h3>What is bedding in sedimentary rocks?</h3>
Bedding is a major feature of sedimentary rocks, that are often composed of strata of sedimentary layers formed one on top of another. Layers of sediments with varying particle sizes are accumulated on top of one another in sedimentary rocks bedding.
Bedding can occur when one distinctively dissimilar layer of sediment is deposited on top of a previous layer or when sedimentary rock is formed with a fresh layer of sediments.
Factors affecting bedding in sedimentary rocks include:
- Erosion
- Sediment size
- Thickness
- Color etc

Answer:
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Explanation:
How does this action explain the differences between seafloor crust and continental crust?
The movements involved in plate tectonics acted like a giant conveyor belt for earths lithosphere and the Mid ocean ridges occur where mantle material rises upward, creating new seafloor crust and pushing plates apart.
Main differences between sea floor crust and continental crusti is that oceanic crust and continental crust are less dense than the mantle, but sea floor crust is denser than continental crust. It also noticed that subduction occurs at ocean trenches, where dense seafloor crust pushes under less dense continental crust, thereby returning seafloor crust to the mantle. The subducting seafloor crust may partially melt, with lower density material melting first and erupting from volcanoes as new continental crust.
Answer:
The most common types of precipitation are rain, hail, and snow.
Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface.
They are classified as follows: Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
