Question

1. several different industries are found along the banks of a river. pollution from these industries ends up in the water. how will this impact earths other systems? (sc.912.l.17.16)

a. pollution will move with the water, disrupting other ecosystems.
b. earths systems are not connected, and do not share pollution.
c. moving water disperses pollution, so it has less effect on ecosystems.
d. water is constantly cycling, so the pollution will eventually break down.

1. human activities...

Explanation:

To solve this, we analyze each option:

• Option A: Earth's systems (like hydrosphere, biosphere, etc.) are interconnected. Polluted river water flows, carrying pollution to other ecosystems (e.g., wetlands, oceans), disrupting them. This matches the concept of interconnected Earth systems.
• Option B: Earth's systems (geosphere, hydrosphere, biosphere, atmosphere) are highly connected, so this is incorrect.
• Option C: While water can disperse pollution, it still negatively impacts ecosystems (e.g., killing aquatic life, affecting food chains), so this is wrong.
• Option D: Many pollutants (like heavy metals, some chemicals) do not break down easily and persist, causing long - term harm. So this is incorrect.

Answer:

A. Pollution will move with the water, disrupting other ecosystems.
