Question

1. how can precipitation patterns affect agriculture?

a. by determining crop selection
b. by altering land elevations
c. by influencing population levels
d. by changing political borders

Explanation:

• Option a: Precipitation patterns (e.g., amount, frequency) determine which crops can grow (e.g., drought - tolerant crops in arid areas with low precipitation), so it affects crop selection.
• Option b: Land elevations are mainly shaped by geological processes like tectonic activity, not precipitation patterns.
• Option c: Population levels are influenced by many factors like economic opportunities, not directly by precipitation patterns affecting agriculture (though agriculture can impact population indirectly, the option's direct link is incorrect).
• Option d: Political borders are determined by human - made agreements, laws, and historical events, not precipitation patterns.

Answer:

a. By determining crop selection
