sramcgin, thanks for your help. you are a very funny person though.
i couldn't find the most eastern and western physiographic region in canada?
in the last ice age ,how many glacial advances?
the process that formed the rocky mountains and the appalachians?
thanks.
Did you check this site?

You're welcome! I'm glad you find me funny. Now, let's help you find the answers to your questions.
To find the most eastern and western physiographic regions in Canada, you can start by looking at a map of Canada. There are various physiographic regions in Canada, each with its own unique characteristics. The most eastern region in Canada is typically considered to be the Atlantic Maritime region, which includes Newfoundland and Labrador, Prince Edward Island, Nova Scotia, and New Brunswick. Conversely, the most western region is usually considered to be the Cordillera region, which includes the Rocky Mountains and parts of British Columbia and the Yukon Territory.
As for the number of glacial advances during the last ice age, it's important to note that there were several glacial advances and retreats over thousands of years. These advances and retreats occurred due to changes in climate and the expansion and contraction of ice sheets. The exact number of glacial advances can vary depending on the specific region or area you are referring to. It might be helpful to consult scientific literature or geological studies to find more detailed information about the specific number of glacial advances in a particular region.
The formation of the Rocky Mountains and the Appalachians can be attributed to a geological process known as orogeny. Orogeny refers to the process of mountain building, which occurs when tectonic plates collide or interact, causing the Earth's crust to fold, fault, or uplift. In the case of the Rocky Mountains, the formation was mainly influenced by the collision of the North American and Pacific Plates. This collision caused the crust to fold and uplift, resulting in the creation of the Rocky Mountains. Similarly, the Appalachian Mountains formed when several ancient continents collided with North America, causing the crust to undergo significant compression and uplift.
I hope this helps! If you have any more questions, feel free to ask.
