Moraines form when a glacier moves down a mountain until it reaches temperatures warm enough to melt. As the ice melts, it deposits sediment. This sediment form ridges called moraines.

The four types of moraines are lateral, medial, terminal, and ground moraines. Lateral moraines form along the sides of a glacier, medial moraines are formed when two glaciers merge and their lateral moraines combine, terminal moraines mark the furthest extent of a glacier's advance, and ground moraines are the debris left behind beneath a glacier as it retreats.
Moraines are found along the edges, flanks, and in the middle of glaciers. They are formed from debris and rocks that have been transported and deposited by the glacier's movement. Lateral moraines form along the sides, medial moraines run down the center, and terminal moraines are found at the glacier's terminus.
Moraines
Glacial ice erosion will form: * Corries (cirques) * Aretes * Pyramidal Peaks * U-shaped troughs * Hanging Valleys * Truncated Spurs * Rouche Moutonees * Striations * Rock Steps Sediment deposition (resulting from glacial processes) will form: * Ice-transported boulders * Erratics * Lateral moraines * Medial moraines * Terminal moraines * Recessional moraines * Push moraines * Varves * Eskers * Delta kames * Kame terraces * Braided streams * Flat bottoms to U-shaped valleys
terminal moranies
Yes, the word 'moraines' is a noun, the plural form of the singular noun 'moraine', a word for an accumulation of soil and rock deposited by a glacier; a word for a thing.
They act like dams or form long ridges of land.
Terminal moraines or terminal
When materials are bulldozed at the front of a glacier, they form a ridge-like feature called a moraine. Moraines are composed of a mixture of rock, sediment, and debris that were pushed and carried by the glacier as it moved forward.
Ridges of rock debris that form in front of a glacier are called terminal moraines at the point that the glacier stops moving ahead.
