Question

The Earth is made up of five interdependent spheres: the geosphere (lithosphere), hydrosphere, biosphere, cryosphere, and atmosphere. The spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres. Changes that take place within an ecosystem are referred to as events. Events can occur naturally or they can be caused by humans. An event can cause changes to occur in one or more of the spheres or an event can be the effect of changes in one or more of Earth’s four spheres. This cause and effect relationship between an event and a sphere is called an interaction.

Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air. Add to this scenario to include an interaction with the biosphere.
Responses
A Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air causing rainfall.Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air causing rainfall.
B Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air causing changes to the weather.Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air causing changes to the weather.
C Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air where it condenses to form clouds.Water in the lake seeps into the cliff walls behind the dam, becoming groundwater, or evaporating into the air where it condenses to form clouds.
D Water in the lake seeps into the cliff walls behind the dam where humans harness energy from the water, allowing excess to become groundwater, or evaporate into the air.Water in the lake seeps into the cliff walls behind the dam where humans harness energy from the water, allowing excess to become groundwater, or evaporate into the air.

Answer 1

D

Reason: option D introduces humans using the water (hydropower), and humans are part of the biosphere. The other choices describe only atmosphere/hydrosphere processes, not an interaction with the biosphere.
