Explanation:

Question 7

To determine why Earth is unique in supporting life, we analyze each option:

• A strong magnetic field (while important) isn't unique to Earth for life support (other planets may have magnetic fields).
• A thick atmosphere alone isn't unique (some planets have atmospheres).
• Abundant sunlight is not unique (many celestial bodies receive sunlight).
• Earth's four spheres (geosphere, hydrosphere, atmosphere, biosphere) interact in ways that create and sustain conditions for life, which is a unique characteristic.

To determine the correct action when unsure about a lab activity:

• Ignoring doubts is unsafe and unwise.
• Following others without understanding is risky and not a good practice.
• Guessing and proceeding can lead to mistakes or accidents.
• Asking a teacher or caregiver is the appropriate action to ensure safety and proper understanding.

Answer:

It has interactions among its four spheres
