The correct answer is - A. Idaho.
The Columbia River is a big river and it flows through the western part of the North American continent. Its path leads it to cross through four federal states, tow of which are Canadian, and two are in the United States. The river starts its flow in Canada, in Alberta, moving in a northwestern direction. After that, it makes a sharp turn and moves in south direction while passing through British Columbia. It crosses the border between Canada and the United States, entering Washington, and after that Oregon, making multiple turns in different direction, and it ends up into the Pacific Ocean.
Answer:
Erosion breaks existing rocks and turns them into sediments. The sediments can be formed into rocks by the chemical reactions of dissolved seashells ( Calcium Carbonate.) This reaction can form sediments into rocks very quickly like the formation of concrete ( same chemical reaction). Erosion only happens on the earth's surface.
As erosion only happens on the earth's surface, sedimentary rocks are only formed on the earth's surface.
In other words:
Sedimentary rocks only found on or close to Earth's surface because sedimentary rocks are made of materials deposited in layers at the Earth's surface.
The information given about convection is true.
It should be noted that geologists posited that convection relates to the movement of tectonic plates. It was stated that convection causes tectonic plates to move.
Tremendous heat and pressure within the Earth bring about hot magma to flow in the convection currents. These movements then lead to the movement of the tectonic plates.
