D. Were nomads who hunted and gathered
<span>I'm not sure I
completely understand what the question is asking for. When I look at
the plates, it looks like they all fit together like a giant puzzle.
They separated due to tectonic plates shifting over hundreds of years.
This was based on the theory that there was a supercontinent (one giant
landmass). I'm not sure how much this helps, but I hope it does. Good
luck!!

Answer:
It is difficult to cross.
Explanation:
The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.
As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.
1. Waves hitting at an angle and then bending around features of the coast is known as wave refraction.
2. Landforms associated with longshore drift form where the sediment is plentiful enough to create them.
3. When there is longshore drift, the overall direction of sand transport is parallel to the coast..
4. In order to produce longshore drift, the direction of waves must not be perpendicular to the coast.
5. A baymouth bar forms when longshore drift creates a ridge of sand separating a waterway from the ocean.
6. The direction that sediment is traveling along a coast is called the downstream direction.
Explanation:
Waves forms different kinds of land form in the coastal areas. Waves hit coast in a particular angle It is known as wave refraction. When sediments get deposited in the coastal areas and forms a bar which get detached from the shore is called long shore bar.
To create long shore drift the direction of wind should not be perpendiular to the coast. Direction will be parallel. A baymouth bar is formed when a ridge of sand is created and separates the waterway from ocean. Sediments travel along the coast in downstream direction.
