End moraine size and shape are determined by whether the glacier is advancing, receding or at equilibrium. The longer the terminus of the glacier stays in one place, the more debris accumulate in the moraine. There are two types of end moraines: terminal and recessional. Terminal moraines mark the maximum advance of the glacier.
A recessional moraine is a ridge of deposited debris that occurs when the glacier is stationary for an extended length of time. [27] This occurs when a glacier meaning the glacier is in equilibrium or has halted during retreat . The occurrence of end moraines can be useful for determining a pattern of advance, retreat, and equilibrium of a ...
One theory proposes that as the glacier melts it leaves behind an accumulation of rock debris in the form of annual recessional moraines. These annual glacial advances and recessions cause parallel ridges to form a few metres apart. Because the accumulation of debris is annual, the moraines do not get very large and stand only a few metres high.
Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki
The terms ground moraine (Grundmoräne), ablation moraine (Ablationsmoräne) and push moraine (Stauchendmoräne) are explained. A distinction is made between recessional or deposited end moraines ( Satzendmoräne , material left behind by the inland ice when the ice melts) and push moraines ( Stauchendmoräne , till heaped up ahead of the ...
A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment.

A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
