Here's why:

* Moraines are not made of calcite. Moraines are accumulations of rock, sediment, and soil transported and deposited by glaciers. They are primarily composed of various types of rock debris, not calcite.

* Moraines are not cone-shaped. Moraines can take various forms, including ridges, mounds, and even scattered deposits. They are formed by the deposition of material as a glacier advances and retreats.

* Moraines are not found in caves. Moraines are landforms created by glaciers and are found in areas that have been glaciated. Caves are formed by different geological processes.

Calcite is a mineral that is commonly found in cave formations like stalactites, stalagmites, and flowstone. These formations are created by the deposition of calcium carbonate from water dripping or flowing through the cave.

In summary: Moraines are glacial landforms, while calcite formations are found in caves. They are distinct geological features with different origins and compositions.
