P Waves (speed): They typically travel at speeds between ~1 and ~14 km/sec.
P Waves (type of motion): They compress and expand (oscillate) the ground back and forth in the direction of travel.
P Waves (type of material the wave travels through): These waves can travel through solids, liquids, and gases.
P Waves (other information): Compressional waves are also called P-Waves, (P stands for "primary") because they are always the first to arrive. They gave us the first jolt last Friday. Shear waves propagate more slowly through the Earth than compressional waves and arrive second, hence their name S- or secondary waves.
S Waves (speed): Speeds are on the order of 1 to 8 km/sec.
S Waves (type of motion): S waves produce vertical and horizontal motion on the ground surface.
S Waves (type of material the waves travel through): S waves only travel through solids.
S Waves (other information): In seismology and other areas involving elastic waves, S waves, secondary waves, or shear waves (sometimes called elastic S waves) is a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.

South America and North America are named after Italian navigator Amerigo Vespucci, who was the first European to suggest that the Americas were not part of the East Indies, but an entirely separate landmass. The portions of the landmass that lie south of the Isthmus of Panama became known as South America.

What steps could Argentina’s government take to address concerns about the effects of an increased dependence on soy?
Answers
Answer:
eat less soy:)
Explanation:
Answer:
Argentine farmers, anxious about an increasingly murky political outlook and economic turmoil, are turning toward soy over more expensive corn to cut costs, a shift that could impact next season’s harvest in one of the world’s top grain exporters.
Farmers said a volatile economic situation in Argentina and the likelihood of a new administration at the end of the year, after President Mauricio Macri was hammered in primary elections, meant soybeans looked a less risky bet than corn.
Corn costs around $500 a hectare to produce, around 70% more than soy, local consultants say, because it requires more investment in fertilizers and new seeds each season.
Dino Garimanno, a farmer in the central Argentine town of Laboulaye, said he was considering replacing his corn with a cheaper option.
“It is a little scary to bury all those dollars in the ground,” he said.
The trend could weigh on Argentina’s 2019/20 corn harvest and bolster the output of soy, analysts said. The country - now at the start of the planting season - is the world’s top exporter of processed soy and the number three for corn exports, behind Brazil and the United States.
Fears over the future government’s policy direction have increased since business-friendly Macri was soundly beaten in the Aug. 11 primary by Peronist rival Alberto Fernandez, rocking markets. Fernandez is running on a ticket with populist ex-President Cristina Fernandez de Kirchner.
Fernandez de Kirchner is highly unpopular with the country’s farmers after bringing in export curbs and taxes on overseas farm sales during her 2007-2015 presidency. The general election is on Oct. 27.
“The (primary) result has generated uncertainty and producers will be changing portfolios to incorporate more lower cost crops,” Pablo Adreani, Buenos Aires-based head of AgriPac consultancy, said in an interview.
Gustavo López, director of consultancy Agritrend, estimated farmers would likely cut the area intended for corn this season by 200,000 hectares, to 6 million hectares. Soybeans would take that area to reach 17.7 million hectares.
