Question

Give reason

3)
Glaciers cause erosion inspite of having less velocity.
4) A country's economy gets affected.

​

Answer 1

Answer:

3. Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion. The sediments and rocks frozen in the ice at the bottom and sides of a glacier act like sandpaper.

4. Glacial till provides fertile soil for growing crops. Deposits of sand and gravel are used to make concrete and asphalt. The most important resource provided by glaciers is freshwater. Many rivers are fed by the melting ice of glaciers.
