In northeastern Ontario there was a large glacial lake, Iroquois, that existed approximately around 13000 years ago. It was a proglacial lake. It was practically an enlargement of today's lake Ontario. It formed because the St. Lawrence River was blocked by an ice sheet, and it drained to the southeast, through a channel passing today's Rome, New York, through the Mohawk River and then in Hudson River. As evidence, there's the sand ridges of Rome, the relief forms in the plains around lake Ontario, the soil structure, the glacial remains.
Answer:
The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our ocean. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps.

A convection current is caused by differences in "temperature".
<u>Option: A</u>
<u>Explanation:</u>
The convection current is the outcome of variations in temperature. Like hot substance which is less denser, it rises while cool material which is more denser, it sinks. It is this motion that produces circulating processes in the environment, in water and in the Earth's mantle identified as convection currents. When air heats up it increases in the atmosphere, enabling colder air to circulate in below. This air flow generates waves, together with the Earth spinning. In effect, winds produce surface waves over the ocean.
