I just want to make sure that I have the correct answers for 2 questions:

1. The western part of North America is more mountainous than the eastern part.

2. Chile is the longest country in South America.

Both are right.

To verify the answers for these questions, let's break down each question and explain how to arrive at the correct answers:

1. The western part of North America is more mountainous than the eastern part.
To confirm this statement, we need to evaluate the geographical features of North America. One way to do this is by looking at a map or using an online mapping tool.

Here's how to find the answer:
- Open up a map of North America, either physical or political.
- Observe the region from an elevation standpoint. You'll notice that the western part (including the Pacific Coast) is characterized by the presence of several mountain ranges such as the Rocky Mountains. The eastern part, on the other hand, generally features lower elevations, rolling hills, and the Appalachian Mountains.
- By comparing the mountainous geography of the western and eastern regions, we can conclude that the statement is correct, as the western part of North America is indeed more mountainous than the eastern part.

2. Chile is the longest country in South America.
To verify this statement, we need to assess the physical dimensions of each South American country. Again, we can use a map or online resources to obtain accurate information.

Here's how to find the answer:
- Access a map of South America, either online or in print.
- Locate the country of Chile on the map and identify its longitudinal extent, stretching from north to south.
- Compare the length of Chile with that of other South American countries, such as Brazil, Argentina, Peru, and Colombia.
- By comparing the longitudinal dimensions of all countries, you will find that Chile is indeed the longest country in South America, extending over 4,300 kilometers (2,670 miles) from top to bottom.

By following these procedures, you can verify the correctness of the provided answers.
