How do glaciers cause erosion and deposition

Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.

Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.

The other way you'll need more informations because my Knowledges are limited by here.

when glaciers (slowly) glide down a mountain they carry down earth and rock and brings it down. After the glacier has completely melted the earth from the mountain id deposited to the lower ground.
