Question

what number might be a good representation for the sea level​

Answer 1

Answer:

zero ( 0)

Step-by-step explanation:

The number that best represents sea level has always been 0. This is because sea level is meant to represent where the initial point where dry land meets the sea all around the world. Seeing since 0 is the universal neutral number which is neither positive or negative, it acts as the perfect number for sea level. Any elevation above sea level is in the positives while elevations under sea level would be in the negatives since it is lower than sea level and lower than 0 is negatives.

Answer 2

Here, we are required to suggest a number which might be a good representation for the sea level.

• A number which might be a good representation for the sea level is zero (0).

• Scientific, mostly geological and geographical calculations usually require a reference point to quantify depth.

• As such, depth in the fields mentioned above is quantified relative to the sea level. For instance, a marine habitat might be located 150m below sea level.

Such quantifications may

fall below or above sea

level.

Therefore, a number which might be a good representation for the sea level is zero (0).

• Consequently, positions below sea level may be expressed as negative, -ve on the number line and positions above sea level may be expressed as positive, +ve on the number line.
