maps

1. the lines on this globe show....

a. longitude
b. latitude

Explanation:

Step1: Recall metric base - units

Time is measured in seconds, mass in grams, temperature in celsius, distance in meters, and volume in liters.
a) seconds
b) grams
c) celsius
d) meters
e) liters

Step2: Recall metric - prefixes

1 kg = 1000 g, 1 hg = 100 g, 1 g = 1 g, 1 cg=0.01 g. So the order from biggest to smallest is kg, hg, g, cg.

Step3: Consider distance scale

The distance between two towns (Elk River to Zimmerman) is large, so km is the most appropriate unit. Answer is c.

Step4: Consider volume of a pop - can

A pop - can has a relatively small volume, so mL is the most appropriate unit. Answer is a.

Step5: Convert volume and mass

a) Since 1 L = 1000 mL, then 345.2 mL=$\frac{345.2}{1000}$ L = 0.3452 L.
b) Since 1 kg = 100000 cg, then 0.654 kg=0.654×100000 cg = 65400 cg.

Step6: Identify globe lines

The lines on the globe shown are longitude lines. Answer is a.

Answer:

1. a) seconds

b) grams
c) celsius
d) meters
e) liters

1. kg
