In 1954, Mt. Everest was measured as having an elevation of 8848 m. In 1998 to 2000, Mt. Everest was measured as having an elevation of 8850 m. Using an average rate of uplift of 6.5 mm/y, how much has Mt. Everest risen since it was first measured?
Please, help me! I don't know how to answer this question!
6.5 * 34 = 221 mm = 22.1 cm
Not sure what you mean by saying that its elevation was 8850m "in 1998-2000" since it is always changing.
From 1954 to "1998-2000" it rose 2 meters, or 200 cm.
Not sure why the average lift rate is given, since we were given the final measurement. Question is poorly worded.
To find out how much Mt. Everest has risen since it was first measured, we need to calculate the difference between its current elevation and its elevation in 1954.
First, let's find out the number of years between 1954 and the year when it was last measured in 1998-2000. We subtract 1954 from 2000 to get 46 years.
Next, we need to calculate how much Mt. Everest has risen on average each year. Given that the average rate of uplift is 6.5 mm/year, we can multiply this rate by the number of years: 6.5 mm/year * 46 years = 299 mm.
To convert millimeters to meters, we divide the value by 1000 since there are 1000 millimeters in a meter: 299 mm / 1000 = 0.299 m.
Therefore, Mt. Everest has risen by approximately 0.299 meters since it was first measured in 1954.
