Question

Glacier movement is similar to a giant bulldozer scraping a pushing rock and soil but the ice and snow also have plastic properties allowing flow downhill driven by ____________ . If the average separation distance of the pipe is 300 meters, and the elapsed time is 1,500 days, what is the average velocity of the glacier?
a. Gravity
b. Sediment
c. 0.2 meters per day
d. 2 millimeters per day
e. 2 meters per year
f. 2 kilometers per day
g. heat
h. Convection

Answer 1

Answer:

A. Gravity

C. 0.2meters per day

Explanation:

1. the answer to this first question is gravity. Gravity is what causes the movement of glaciers; the ice would flow slowly and it would deform as it responds to gravity. therefore the answer here is a.

2. average separation distance of pipe = 300 meters

elapsed time = 1500 days

the average velocity of the glaciers would be

300 meters/1500 days

= 0.2 meters per day.

therefore the answer is c
