Question

a large part of basin is flat, mountains. etc​

Answer 1

Answer:

A basin landform consists of an area of land, usually like a smaller prairie, enclosed by higher land such as hills and mountains. A basin does not have to consist of lowland like a prairie. It can consist of land such as a desert or even an arctic desert.

Explanation:

These mountains are coined a "desert mountain island" because they are surrounded by a "sea" of desert. This region is called the Great Basin because the streams and rivers have no outlet to the sea; instead, water collects in salt lakes, marshes and mud flats, where it eventually evaporates.

Answer 2

A geological basin is a large low-lying area. It is often below sea level.
