Glacier deposits can form in Africa due to historical climatic changes, particularly during the ice ages when temperatures were significantly cooler. Regions such as the East African Highlands and the Atlas Mountains in North Africa may have experienced glaciation, allowing glaciers to carve and deposit sediments. Additionally, geological processes, like uplift and tectonic activity, can create conditions conducive to glaciation, even in typically warm climates. Evidence of past glacial activity is found in the form of moraines and striations in these areas.
What else can I help you with?
How does a till form?
Formed when a mixture of sediments that a glacier deposits directly on the surface
How does till form?
Formed when a mixture of sediments that a glacier deposits directly on the surface
How do glacial deposits support the idea of continental drift?
With continents in their present positions, the till deposits do indicate erratic glacier motion. When continents are fitted together, they show much more streamlined motion of the glacier from the southern Africa and the Northern Australia outward.
When does a glacier deposit the sediment it is carrying?
When a glacier melts it deposits the sediment it eroded from the land, creating various landforms.
When a glacier stops moving forward a may be deposited?
When a glacier stops moving forward, it deposits the sediment it carried in the form of moraines. Moraines are piles of rocks, debris, and soil that accumulate at the edge or front of a glacier. They can serve as markers of past glacier extent and movement.
What formation is small hill like mound formed from the deposits as the glacier recedes?
drumlin
Which formation is a small hill-like mound formed from the deposits as the glacier recedes?
A small hill-like mound formed from the deposits as a glacier recedes is called a moraine. Moraines are composed of till, which is a mix of rock, sediment, and debris that the glacier carries and deposits as it moves and melts.
What does a glacier do to the surface of the earth as it recedes?
the glacier deposits various rocks and sediment it displaced as it moved forward
What does a glacier deposit as it recedes?
As a glacier recedes, it deposits materials such as rocks, sand, and gravel that were previously frozen within the ice. These deposits are known as glacial moraines and can vary in size and composition depending on the glacier's movement and the type of material it picks up along its path.
Small hills that are formed form deposits left by streams on the surface of glacier are called?
Kames. Many are found in areas of kettles and moraines.
Is the glacier in Kilimanjaro Africa bigger than the glacier in Vermont?
NO!
What type of rock form when glaciers move along mountains and break off sediments?
Glacial deposits may form when glaciers move along mountains and break off sediments. These deposits can include a variety of sediment types such as till, moraines, and erratic boulders. As the glacier moves, it erodes and transports these sediments, eventually depositing them once the glacier melts.
