Glaciers deposit their sediment when they melt. They drop and leave behind whatever was once frozen in their ice. It’s usually a mixture of particles and rocks of all sizes, called glacial till. Water from the melting ice may form lakes or other water features. Moraine is sediment deposited by a glacier. A ground moraine is a thick layer of sediments left behind by a retreating glacier. An end moraine is a low ridge of sediments deposited at the end of the glacier. It marks the greatest distance the glacier advanced.
A drumlin is a long, low hill of sediments deposited by a glacier. Drumlins often occur in groups called drumlin fields. The narrow end of each drumlin points in the direction the glacier was moving when it dropped the sediments.
An esker is a winding ridge of sand deposited by a stream of meltwater. Such streams flow underneath a retreating glacier.
A kettle lake occurs where a chunk of ice was left behind in the sediments of a retreating glacier. When the ice melted, it leaves a depression. Hope this helps ;)
Answer:
Earth has a moving, morphing which has lead to the evolution of life forms.
Explanation:
- A continental plate or slab of rocks that form a landmass consists of lighter elements like silicon and aluminum and has a low density. It's formed by the heating and cooling of magmas over the surface is called the crust.
- The existence of life on earth would have not been possible if the continental plates were not formed, the earth is itself active and evolving this evolution led to the formation of the seven continent; landmasses and ocean basins as below them the earth is moving.
- Spreading of the lavas on ocean floor and the formation of rocks with different compositions and not only that plate tectonics have modulated the atmosphere also they are the driving creation of motion of tides and life-giving nutrients. Thus life emerged from the earth's ocean bottoms.
