Glacial deposits have been found in Africa because the continent experienced multiple glacial periods in the past when the climate was much colder. During these periods, glaciers formed and deposited sediment as they moved, leaving behind evidence of their presence in the form of rock formations and moraines. This geological evidence helps scientists understand the changes in climate and landscape that have occurred in Africa over millions of years.
Even today there are glaciers in Africa - on Mt Kilimanjaro. In the geological past, Africa had occupied a position such that the geographic south pole was in the African continent.
With the break-up of Gondwana Land, the present Antarctic continent broke away and eventually the present land masses assumed their current positions. These motions continue today, Australia for example is moving northerly at about 200 mm per year. Over a few million years, these numbers add up.
The inselbergs of Africa are considered by some to be glacial created features, though the term applies to the shape of them rather than their creation.
This area of geological study is rapidly expanding.
frica has not always been near the equator, long ago when Wegener made an hypothesis that earths landforms were once all one landmass called Pangaea. When Pangaea was a whole, Africa was more near the poles than where it is located now.
Because when Pangaea was a whole, Africa was more near the poles than where it is located now.

Why have glacial deposits been found in Africa?

Where gold is mainly found?
Gold is mainly found in underground deposits, often associated with quartz veins or sedimentary rocks. Large gold deposits are also found in placer deposits, where gold has been eroded from its source rock and transported by water into streams and rivers. Gold can be found in many parts of the world, with major producers including Australia, Russia, the United States, and South Africa.
What is the evidence that Africa was once cold?
Evidence of Africa once being cold includes the presence of glaciers, glacial deposits, and ancient ice sheets in different parts of the continent. Additionally, fossil evidence of cold-adapted species, such as woolly mammoths, have been found in regions of Africa that are now tropical. Paleoclimatic data from sediment cores and ice cores also provide insights into past temperature fluctuations.
How do you describe the drift plains?
Drift plains are flat expanses of land covered in sediment deposits left behind by glaciers or rivers. These deposits consist of a mixture of soil, rocks, and other debris, creating a fertile landscape suitable for agriculture. Drift plains are often found in regions that have been shaped by ice ages or glacial activity.
What is a feature created by glacial deposites?
A feature created by glacial deposits is a moraine. Moraines are accumulations of rocks, sediment, and soil that have been pushed along and deposited by a moving glacier. They can take the form of ridge-like mounds or long, winding ridges across the landscape.
What term describes all types of glacial deposits?
The term that describes all types of glacial deposits is "glacial drift." This includes materials such as rocks, gravel, sand, and clay that have been transported and deposited by glaciers.

Where are the malachite deposits in South Africa?
Malachite has been found at Musina, at the Stavoren tin mines, and in the Kalahari manganese field, with good specimens found at. among others, Palabora, Kwaggafontein, Vergenoeg and Leeuwenkloof.

What are some deposits of alpine glaciers?
Some deposits of alpine glaciers include moraines (such as lateral, medial, and terminal moraines), drumlins, eskers, and outwash plains. These deposits are created as the glacier erodes, transports, and deposits sediment during its movement.
Have diamonds been found in Georgia?
Georgia is not known for its raw diamond deposits.
Sediment left behind when a glacier melts is called?
The sediment left behind when a glacier melts is known as glacial till. Glacial till is a mixture of different-sized rock fragments that have been eroded and transported by the glacier as it moved.
Most early hominid fossils have been found in?
The oldest humanoid fossils were all found in Africa.
Where is anthracite found?
In metamorphosed coal deposits, usually in mountain forming regions. Substantial deposits exist and have been mined in Pennsylvania, USA.
