<u>Evidence of a large glacial lake northeastern Ontario:</u>
The evidences of a large glacial lake in northeastern Ontario are, sand ridges of Rome, relief forms in the plain around the lake in Ontario, the structure of the soil and the glacial remains.
This large glacial lake was named Iroquois which existed approximately 13000 years ago and is said to be enlargement of today's Ontario lake. This was formed because the St Lawrence river was blocked by an ice sheet and it drained towards the south east.
The correct answer is - C. The river carried enormous amounts of silt.
The Yellow River, got this nickname because it is yellowish from the enormous amounts of silt it carries. When there were heavy rains, or the snow was melting, the river got more water, but also more silt, so the silt was partially blocking the free movement of all of the water, so it was flooding the surrounding are. In one way, the floods were terrible because they were destroying pretty much everything on their way, but on the other side, were living huge amounts of deposits that were fertilizing the soil for the agriculture.
In 1914, Archduke Franz Ferdinand of Austria and his wife Sophie are shot to death by a Bosnian Serb nationalist during an official visit to the Bosnian capital of Sarajevo. The killings sparked a chain of events that led to the outbreak of World War I by early August.
