Question

why is a lake such as the one pictured considered an open system? it is isolated by the mountains surrounding it. there is an input and output of energy and water. there are no interactions with other bodies of water.

Explanation:

An open system is defined as a system that exchanges both matter and energy with its surroundings. In the case of a lake, it receives inputs such as water from rivers, rainfall, and energy from the sun. It also has outputs like water flowing out through rivers or evaporation (losing water as a form of matter) and heat loss (energy output). Options that suggest isolation (by mountains or no interaction with other water bodies) would imply a closed or isolated system, which is the opposite of an open system.

Answer:

There is an input and output of energy and water.
