Question

Which of the following statements is incorrect?

A) The Earth orbits the Sun.
B) Water boils at 100 degrees Celsius at sea level.
C) Oxygen is a greenhouse gas.
D) The moon emits its own light.

Answer 1

The incorrect statement is 'The moon emits its own light' because the Moon does not generate its own light; rather, it reflects sunlight.

Step-by-step explanation:

The incorrect statement among the options provided is: D) The moon emits its own light. Let's analyze each statement:

• A) The Earth orbits the Sun: This is a correct statement; the Earth revolves around the Sun in an elliptical orbit.
• B) Water boils at 100 degrees Celsius at sea level: This statement is accurate; water reaches its boiling point at 100°C at standard atmospheric pressure, which is usually at sea level.
• C) Oxygen is a greenhouse gas: While oxygen itself is not a greenhouse gas, it's often confused with ozone (O3), which is. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3).
• D) The moon emits its own light: This statement is incorrect. The Moon does not emit its own light but reflects the light of the Sun.

Hence, the answer is that the statement 'The moon emits its own light' is not true.
