How Long for a Glacier to Move 0.74 km?

  • Thread starter licia589
  • Start date
In summary, to determine how many years it would take for the glacier to move 0.74 km, you will need to convert the speed from nanometers per second to kilometers per year and then use the conversion factor to find the time it would take for the glacier to move 0.74 km. You will also need to know how many seconds there are in a year, which is 365.242190 days.

a glacier moves with a speed of 41 nm/s. how many years would it take for the glacier to move 0.74 km. answer in units of yr..

ok how do i solve this?

would i multiply 41
.74 and just convert it to yrs?

Have you forgotten where the homework section is already?

This is just a matter of correcting the units.

Since the speed is given in nm/s (nanometers per second) but you are given a distance in km and asked for an answer in years.

You will need to know how many nanometers there are in a km. I don't happen to remember what a nanometer is so you will have to look that up (it will probably be given as so many nanometers per meter so you will still need to convert to kilometers.

You will also need to determine how many seconds there are in a year! That shouldn't be difficult: there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365.25 hours in a year.

1. How do glaciers move?

Glaciers move as a result of gravity pulling them down a slope. The weight of the ice causes it to slowly flow and deform over time.

2. What factors affect the speed at which glaciers move?

The speed of glacier movement is affected by several factors, including the slope of the underlying terrain, the amount of ice present, and the presence of meltwater at the base of the glacier.

3. How long does it take for a glacier to move 0.74 km?

The time it takes for a glacier to move 0.74 km can vary greatly depending on the glacier's size, location, and surrounding environment. It could take anywhere from a few weeks to several years.

4. What is the average speed of glacier movement?

The average speed of glacier movement is typically very slow, ranging from a few centimeters to a few meters per day. However, some glaciers have been known to move at faster speeds of up to several meters per hour.

5. Can glaciers speed up or slow down over time?

Yes, glaciers can speed up or slow down over time due to changes in environmental conditions such as temperature, precipitation, or the amount of meltwater present. They can also be affected by human activities such as mining or construction.
