Certainly! Let's carefully walk through the steps to determine the difference between the highest and lowest temperatures recorded on Earth.
1. Identify the Lowest Temperature:
- The lowest temperature recorded on Earth is given as \(-89\) degrees Celsius.
2. Identify the Highest Temperature:
- The highest temperature recorded on Earth is given as \(57\) degrees Celsius.
3. Calculate the Temperature Difference:
- To find the difference between the highest and lowest temperatures, we subtract the lowest temperature from the highest temperature.
\( \text{Temperature Difference} = \text{Highest Temperature} - \text{Lowest Temperature} \)
Given:
- Highest Temperature: \(57\) degrees Celsius
- Lowest Temperature: \(-89\) degrees Celsius
Substitute these values into the formula:
\( \text{Temperature Difference} = 57 - (-89) \)
4. Simplify the Expression:
- Subtracting a negative number is the same as adding the absolute value of that number. Thus:
\( \text{Temperature Difference} = 57 + 89 \)
5. Perform the Addition:
- Now, add the two numbers together:
\( 57 + 89 = 146 \)
6. Result:
- The difference between the highest and lowest temperatures recorded on Earth is \(146\) degrees Celsius.
Summarizing, the lowest temperature recorded on Earth is [tex]\(-89\)[/tex] degrees Celsius, the highest temperature recorded is [tex]\(57\)[/tex] degrees Celsius, and the difference between these two temperatures is [tex]\(146\)[/tex] degrees Celsius.
