How do you measure the thikness of the ice?

Question

If you need to determine wheather or not ice is thick enough to skate how would you do that?

Answer 1

It's not so much the thickness but the strength of the ice. Thick ice on a large lake can be more likely to break than thin ice on a small pond - partly it's the distance the ice has to span. Also if the ice is held in place by water underneath it (sometimes there's air between the ice and water), if there's trapped air the ice is like a bridge but if it's water then this supports the ice.

Ice is pretty strong stuff but some ice is stronger then others, there can be weaknesses and even thick ice can crack along the weak lines.

To physically measure the thickness then drill a hole in it. The ideal tool is an ice-auger which can drill through deep ice.

My own test for detemining the strength of ice is to throw a large rock onto it - if the ice survives the impact it shouldn't have difficulty supporting my weight.

Wow, you will think of the information media would supply this the comparable quantity of interest they supply melting glaciers, desperate polar bears, and violent hurricanes. Wait a minute, come to think of of it, they infrequently boost observations of organic occurrences that would desire to solid doubt on their sought after disaster. fact is, they have been bought down the river earlier on the AGW concept. they have not any difficulty protecting up or distorting the fact to sell their left-wing time table. Many advocates have been quoted extremely of course to that influence. that is okay to to be cheating if their intentions are "stable." That mentality is plenty extra stressful than our climate getting somewhat warmer, no remember the reason. i do no longer think of people get this,.... of course no longer. This concern is so plenty better than in basic terms some undesirable technological expertise. that is possibly the main important occasion of "groupthink" considering Hitler's Nazi Germany. people hate that assessment, yet i think of it applies.

Answer 3

The experts cut a small hole and measure it.

Answer 4

with a ruler stupid!
