What are erratics?
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
Ridge left by a glacier?
The ridge formed from till deposits at the edge of a glacier is called a moraine. It may be formed from glacial flours or from large boulders.
Is glacial lake caused by erosion or deposition?
A glacial lake is a lake with origins in a melted glacier. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks.

What are large deposits of boulders called?
The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.

Why are northern plain primarily agricultural belt?
due to large alluvium deposits and fertile soil next to the rivers
Depressions left by melted blocks of ice in glacial deposits?
The depressions left by melted blocks of ice in glacial deposits are called kettle holes. They are circular or oval-shaped depressions that form when large chunks of ice left behind by a retreating glacier become buried in sediment. When the ice eventually melts, it creates a hole in the ground.
