Explanation:
The First wave of Immigration to the U.S. were mostly White, Protestant Europeans from Germany and England. The second wave of Immigration to the U.S. consisted of immigrants fleeing Eastern European and Mediterranean countries because of either religious reasons or economic reasons, this group of immigrants faced discrimination in the U.S. The third wave of immigration to the U.S. mainly consists of immigrants from Latin America and Eastern Asia. Immigration from Latin America has accelerated in the past 40 years due to decades of corruption and war that has been caused by American intervention in the region during the 70s and 80s.
When a river meets an ocean and spreads into what looks like a triangular shape, the landform or body of water being created is called a<u> Delta</u>.
Deltas are:
- Formed at the point where a river meets another body of water
- Formed such that they have a triangular shape
- Caused by water erosion
Deltas take a triangular shape at the mouth of a river when the river is meeting a water body such as a lake or ocean.
They form because of water erosion resulting from when the river picks up soil particles and carries them to its mouth where they are deposited and obstruct the flow of water thereby creating a delta.
In conclusion, erosion causes a delta to form when water carries soil and deposits it at its mouth.

Seafloor mapping during WWI and the Cold War had revealed the details of the physical structure of the ocean ridge system, and discovery of magnetic stripes on the ocean floor was the crucial turning point in development of plate tectonic theory. when deep-sea line soundings (bathymetric surveys) were routinely made in the Atlantic and Caribbean.

Answer:
James Hutton
Explanation:
James Hutton was the geologist who brought this concept of 'Uniformitarianism'. This law describes that all the geological processes that occur now must have taken place in the geological past, with varying intensities, and these processes are responsible for the configuration of the landscape and formation of various surface features on earth.
This was an important discovery that led to a better understanding of the geological processes and how they act on the earth's surface and in its interior.
