Question

why is earth systems science considered interdisciplinary? it focuses on a single scientific discipline; it combines multiple scientific disciplines to understand earth as a whole; it only studies the atmosphere

Explanation:

To determine why Earth Systems Science is interdisciplinary, we analyze each option:

• The first option ("It focuses on a single scientific discipline") is incorrect because interdisciplinary means combining multiple disciplines, not focusing on one.
• The second option ("It combines multiple scientific disciplines to understand Earth as a whole") is correct. Earth Systems Science integrates fields like geology, meteorology, biology, etc., to study Earth's components (atmosphere, hydrosphere, biosphere, geosphere) and their interactions as a unified system.
• The third option ("It only studies the atmosphere") is incorrect because Earth Systems Science studies all of Earth's systems, not just the atmosphere.

Answer:

B. It combines multiple scientific disciplines to understand Earth as a whole
