Answer 1

difference between Canadian shield and central lowland​

Canadian shield

• The age of the Canadian Shield exceeds 3.96 billion years. The Canadian Shield previously possessed mountains with jagged peaks higher than any of the ranges we see now, but erosion over millions of years has transformed these mountains into undulating hills.
• It was formerly mountainous, but erosion has levelled it down, leaving granite that has been covered in soil and dotted with lakes.
• The Niagara Region lies on a section of a great plain that extends from the northern Laurentian Highlands (Canadian Shield), which are located about 161 km north of Toronto, Ontario, to the southern Allegheny Plateau, which forms the foothills of the Adirondack Mountains and the Appalachian Mountains.

central lowland​

• Because of glacial scouring during the ice age, the presence of massive glacial lakes, and erosion from catastrophic meltwater outbursts, the Central Lowland has a relatively smooth and level surface.
• The Central Lowland is a level region that lies between the Great Plains to the west and the Appalachian Mountains to the east. It spans from the Canadian Shield in the north to the Atlantic Coastal Plain in the south and is a component of the North American Craton (the older, stable part of the continent).
• The Osage Plains are a section of the Central Lowlands, which are located in the broader Southwest region and run through eastern parts of Kansas, Oklahoma, and northeast Texas. Some of the most fertile places in the United States are the low hills and rolling plains of the Central Lowlands.
