<u>Answer:</u>
The three statements that support the idea that South America is a single cultural region are as below:
- In most Latin American countries, the majority of locals speak Spanish.
- The "Mardi Gras tradition" is celebrated with "grand parades" in Brazil, Colombia, Argentina and Uruguay.
- Many people in Argentina, Chile, Peru and Ecuador practice Roman Catholicism.
<u>Explanation:</u>
- Countries like Argentina, Bolivia, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay, and Venezuela are Spanish speaking countries.
- The festival of El Carnaval is celebrated in most South American countries.
- The tradition of Mardi Gras is a part of El Carnaval. 69% of the total "South American population" practices Roman Catholicism.
By weakening and fracturing rock, weathering processes release nutrients and improve subsurface permeability. It is helpful to limit the physical attributes of materials produced by weathering inside the crucial zone in order to better understand these processes.
The permeability, strength, and seismic anisotropy of foliated rocks can be measured geophysically, whereas the first two have effects on hydrology and geomorphology. Characterizing weathering-dependent changes in rock fabric with depth may have a variety of implications because each of these types of anisotropy is connected to rock fabric.
The key points are:
- In the critical zone, seismic surveys of weathered material reveal seismic anisotropy magnitudes that can reach 36% and that change with depth.
- The strike of foliation and fracture planes found in bedrock coincides with the fast direction of wave propagation in weathered materials.
- As bedrock is exhumed toward the surface, in-situ weathering processes probably intensify the anisotropy already existing in the rock.

It can change the ecosystem and it will erode the coasts. The water takes what it wants.
During the second major wave of immigration, from the late 1800s to early 1900s, immigrants to the United States came mostly from Asia and Eastern and Southern Europe. Most of the immigrants that came to the United States were poor people. I hope the answer helps you.
