Why have glacial deposits been found in Africa?
Africa 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.
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?
The glaciers have eroded and chemically changed substinences on Africa. Years and years caused large pileups and created vast deposits of hydrocarbons, which are fossil fuels. (Also notice that hydrocarbons has the root hyro- in it, which means water)
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?
till is the name of the material. In most cases all glacial-related deposits are unsorted and unstratified.

Which characteristics of an erratic distinguishes it from other glacial features?
Erratics are distinctive because they are large boulders or rocks that have been transported and deposited by glacial ice, often far from their source location. Unlike other glacial features, such as moraines or drumlins, erratics can be composed of rock types that are not found in the surrounding area, highlighting their unique origin. Their irregular shapes and sizes also set them apart from more uniform glacial deposits. Additionally, erratics are often found in contrasting geological contexts, making them notable landmarks in the landscape.

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 is a mixture of sediment a glacier deposits in the surface?
A mixture of sediment that a glacier deposits on the surface is called "glacial till." This material is composed of various sizes of sediment, including clay, silt, sand, gravel, and boulders, which have been eroded and transported by the moving ice. When the glacier melts, it drops this unsorted debris, forming landforms such as moraines, drumlins, and outwash plains. Glacial till is significant for understanding past glacial movement and the geological history of an area.

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.
How did wegener use climate evidence to support his hypothisis?
Alfred Wegener used climate evidence to support his hypothesis of continental drift by analyzing the distribution of coal deposits, glacial deposits, and tropical plant fossils across different continents. For instance, he noted that coal deposits in North America and Europe indicated a warm, tropical climate, suggesting these landmasses were once closer to the equator. Conversely, glacial deposits found in currently warm regions like India and South America indicated that these areas had once been situated near the poles. This climate evidence helped demonstrate that continents have shifted over geological time, supporting Wegener's theory of continental drift.
Have diamonds been found in Georgia?
Georgia is not known for its raw diamond deposits.
