If Greenland ice sheet melted, approximately how much would the sea level rise worldwide?
(1 meter =3.28 feet)
a. 500 feet
b. 16.4 feet
c. 50 feet
d. 164 feet
How many meters would it rise?
yeah, that's all the question give me. I don't understand it. those are my only answers.
would you be able to help?
you need to find the volume of the ice sheet
Then you need to figure how many m^3 of water that would be when melted
Then you need to find the area of the earth's water surface.
Then divide the ice-water volume (m^3) by the earth's water-surface area (m^2), giving the depth increase (m)

Ice Sheet Volume
• Total volume of ice contained in the ice sheet: 2.931 x 106 km3 (Bamber et al. 2001)
o This is the equivalent to an additional 7 m of global sea level rise.
• Ice sheet volume: 2.911080129751762 x 1012 m3 (calculations by R. Huff using Bamber et al. 2001)
• Total ice volume estimated at 2.620 x 106 km3 (Ohmura et al., 1999)
o This is the equivalent to an additional 6.7 m of global sea level rise, without considering the effect of hydro-isostacy.
To answer this question, we need to consider the volume of the Greenland ice sheet and its potential impact on global sea levels.
Step 1: Find the volume of the Greenland ice sheet.
The volume of the Greenland ice sheet can be estimated by multiplying its surface area by its average thickness. According to scientific studies, the surface area is approximately 1.71 million square kilometers, and the average thickness is about 1.6 kilometers (or 1,600 meters).
Volume of Greenland ice sheet = Surface area × Average thickness
Volume = 1.71 million sq km × 1,600 meters
Step 2: Convert the volume from cubic meters to cubic feet.
Since the answer choices are provided in feet, we need to convert the volume from cubic meters to cubic feet. The conversion factor is 1 cubic meter = 35.31 cubic feet.
Volume in cubic feet = Volume in cubic meters × 35.31
Step 3: Calculate the sea level rise.
To determine the sea level rise, we need to divide the volume in cubic feet by the total surface area of the oceans (approximately 361.1 million square kilometers).
Sea level rise in feet = (Volume in cubic feet / Surface area of oceans) × 1 meter / 3.28 feet
Now, let's calculate the sea level rise for each given option:
Option (a): 500 feet
Sea level rise = [(Volume in cubic feet / Surface area of oceans) × 1 meter / 3.28 feet] = 500
Option (b): 16.4 feet
Sea level rise = [(Volume in cubic feet / Surface area of oceans) × 1 meter / 3.28 feet] = 16.4
Option (c): 50 feet
Sea level rise = [(Volume in cubic feet / Surface area of oceans) × 1 meter / 3.28 feet] = 50
Option (d): 164 feet
Sea level rise = [(Volume in cubic feet / Surface area of oceans) × 1 meter / 3.28 feet] = 164
After calculating the sea level rise for each option, we can determine the correct answer based on the calculations.
7*3.28 = 23 feet
If that is all correct
