Question

what are the major landforms in canada and their relationship to u.s. geography?
a rocky mountains span both countries
b great plains extend from canada to u.s.
c canadian shield is only in canada
d appalachian mountains start in canada

Explanation:

To solve this, we analyze each option:

• Option A: The Rocky Mountains do span both Canada and the United States, which is a correct statement about the landform's relation to US geography.
• Option B: The Great Plains do extend from Canada to the US, but the question is about major landforms and their relation, and we need to check accuracy. However, the Rocky Mountains' span is a key shared landform.
• Option C: The Canadian Shield is mainly in Canada but also extends slightly into the US (like Minnesota), so "only in Canada" is incorrect.
• Option D: The Appalachian Mountains start in Canada? No, they start in the US and extend into Canada? Wait, actually, the Appalachian Mountains start in the US (eastern US) and extend into Canada's Maritime provinces. So the statement "start in Canada" is incorrect.

So the correct option is A as the Rocky Mountains span both countries, making it a major landform shared between Canada and the US in terms of geography.

Answer:

A. Rocky Mountains span both countries
