Kames:
* Formation: Kames form from sediment accumulation within a glacier.
* As a glacier melts, meltwater flows through crevasses and moulins (vertical shafts) carrying sediment.
* This sediment gets deposited within the ice, forming mounds.
* When the glacier melts away, these mounds of sediment are left behind as kames.
* Appearance: Kames are typically rounded, conical hills, often with steep sides. They can vary in size, but are generally smaller than eskers.
Eskers:
* Formation: Eskers form from sediment deposition within a meltwater channel that flows beneath a glacier.
* As a glacier moves, it creates tunnels and channels under its ice.
* Meltwater flowing through these channels carries sediment, which is deposited along the channel floor.
* As the glacier retreats, the channel's sediment is left behind as a long, winding ridge.
* Appearance: Eskers are long, winding ridges, often with a sinuous shape. They can be quite long and continuous, unlike kames which are more isolated mounds.
Here's a simple analogy:
Imagine a glacier as a giant ice cream cone.
* Kames: Like a scoop of ice cream that falls into the cone and gets trapped, sediment is deposited within the ice to form a kame.
* Eskers: Imagine a straw going through the ice cream cone. Meltwater flowing through the straw carries sediment, which deposits along the straw's path, creating the esker.
In summary:
* Kames are mounds formed by sediment deposition within a glacier.
* Eskers are ridges formed by sediment deposition within a meltwater channel under a glacier.
