Answer:
About 1000 years.
Explanation:
As the exact origin of the Bantu speaking people, it is hard to gauge the exact timeline. However, it is believed that the Bantu expansion arrived in South Africa around 300 AD. This is known by the evidence of their expansion through the development of their language. Expansion moved from central Africa to Southern Africa through modern-day Namibia and Mozambique over time. Terracotta masks give clear indicators of the civilization spreading to South Africa.

when discharge is high vertical erosion erodes the river bed and larger sediments are transported by transaction the river channel is at its widest and defence as a flow towards its mouth the position is the main process in this part of the river which creates large floor plans and deltas
The answer is destructive force.
Constructive force is the force that makes or forms the mountains and other features. Superposition forces are topics to be discussed in theories in <span>physics and systems and may not be applicable here. Unnatural is just an unusual choice. </span>
Answer:
True, majority of the earth energy source comes from the <u>internal motion</u> but rest comes from outside.
Explanation:
- Earth gets its energy from the interior of the planet like the core which forms the most essential driving force of the planet it not just only regulate the flow of geomaterial from the bottom to the top but also acts as a geothermal source for various energy process.
- As we know this is called the Endogenetic force of the planet caused due to the earth rotation without which earth would have been dead long ago. The external forces of Denudation which break down the landscape from above are of Exogenic in nature.
- The sun's rays that are 100% at the surface of the earth but, come down o only 50% at the ground level as most of it gets deflected by the natural Albedo of the earth with is 35%. This partial absorption, deflection, and then reflection
- Thus this process is a temporary phase as all this gets reradiated back in a long wave from at night.
- Thus internal thermodynamics has a huge role to play in the formation of earth energy processes.
