Answer 2

Answer:

Answer:

As per the question, scientists find a dense rock on earth's surface that is made of Mg and smaller amounts of Al and silicon is found in Mantle beneath the earth's surface.

Explanation:

As the structural composition of the earth is made up of primarily three layers i.e earth crust, core and mantel being the second layer found just below the surface of the earth is primarily and mostly composed of Aluminum and rocks that have silicon in them.

So the layer that is below this is made of desert rock matter hence it's composed of Mg and iron and other elements.

The study of this layer of the earth helped the scientists to identify the various types and patterns of tectonic movements inside the earth and also as this layer is responsible for the free flow of lava and magma flows at greater depths.

Answers

Tom Watson, as a populist Georgia politician, was most likely to support farmer and working-class interests. Therefore Option (C) is correct.

Who was Tom Watson?

Thomas Edward Watson (1856 – 1922) was a Georgia politician, lawyer, newspaper editor, and writer. As the leader of the Populist Party in the 1890s, Watson championed poor farmers while opposing business, bankers, railways, Democratic President Grover Cleveland, and the Democratic Party.

Watson was elected to the U.S. House Of representatives in 1890 and pushed through legislation establishing Rural Free Delivery, which was regarded as the "largest and most expensive project" ever undertaken by the United States Postal Service.

Politically, he was a left-wing leader in the 1890s, rallying impoverished whites and poor blacks against the elites. After 1900, however, he moved to nativists' assault on blacks and Catholics (and after 1914 on Jews).

Hence, Option (C) is correct. Tom Watson supported the causes of farmers and the working class.

Why was the construction of the Erie Canal such a great challenge?

Answers

The Erie Canal had no engineers working on it in many sections. The amateurs in charge of it could only survey with the compass, chain and level. Men would agree to be responsible for a section at a time. They would dig by hand and uses horses to haul the dirt away. There was a problem when they got to Lake Erie because the Hudson River was 600 feet below the Lake Erie. They had to dig through limestone and mountains to get to Lake Erie. They lost 1000 workers in one season due to malaria.
