Earth's average temperatures is 14 degrees Celsius.

A true
B False

A. True

B False. The average temperature of the Earth is approximately 15 degrees Celsius (or 59 degrees Fahrenheit).

To determine whether the statement is true or false, we can use scientific data. The average temperature of Earth is a subject of ongoing study and is influenced by various factors. To get the most accurate and up-to-date information, we can refer to reliable sources such as scientific organizations or climate monitoring institutions.

One widely recognized source is NASA's Goddard Institute for Space Studies (GISS) which provides global temperature data. According to their analysis, the average global temperature in recent years has been higher than 14 degrees Celsius. For example, the global temperature average in 2020 was approximately 15 degrees Celsius.

Therefore, based on available scientific data, we can conclude that statement B is False.
