Which of the following best describes a characteristic of rivers compared to lakes?

Rivers are characterized by their flowing nature, which distinguishes them from lakes. They are moving bodies of water that typically flow in one direction, often from higher elevations to lower elevations, such as from mountains to oceans or seas. This continuous movement is driven by gravity and creates ecosystems that support a diverse range of organisms adapted to flowing water.

In comparison, lakes are generally standing bodies of water, which can sometimes lead to the water becoming stagnant. The characteristic flow of rivers is integral to their ecology, influencing the distribution of nutrients and the types of organisms that can inhabit them. The definition of rivers as flowing water bodies is a fundamental aspect of their nature, setting them apart from other aquatic environments.
