How are a glacier and a bulldozer alike?
They're not
True or false When a glacier is retreating the upstream ice is still moving forward toward the downstream terminus of the glacier?
A retreating glacier is one that is diminishing more in length that its upper supply regions can compete with. The snout of the glacier is retreating, but the main body of the glacier is still moving forwards. If this situation continues, the glacier will disappear.
Under what circumstances will the front of a glacier advance?
A glacier is always moving forward (downhill). In the winter, the glacier usually isn't melting and its front edge (or "toe") will advance downhill. In the summer, the toe of the glacier usually melts faster than the glacier is moving forward, causing the front edge of the glacier to recede. If the recession in the summer is greater than the advance in the winter, then the glacier as a whole is receding and will eventually disappear. That is what is currently happening to most of the glaciers in North America and many other places around the world.
Where do you find moraines?
A moraine is the accumulation of solid material - rock, gravels, sand and clay, carried by a glacier, and deposited when the glacier shrank. The material is mainly from avalanches off surrounding mountains, which include rocky material as well as ice and snow.
What could be the effects of material left by a glacier?
glacier is not only transport materia,but they sclupt and crave away the hole land ;;;;pp

How a bulldozer is not a accurate model of how glaciers cause rocks to move in grooves in rocks and other formations on the surface of the earth?
A bulldozer simply pushes loose material in front of it. A glacier is a continuously-fed, rasp-like structure that will push debris in front of it, but its main action is from ice-plucking and abrasion by rocks trapped in the ice in its base.
What does a glacier do to the surface of the earth as it recedes?
the glacier deposits various rocks and sediment it displaced as it moved forward
When a glacier stops moving forward what will be deposited in front of it?
When a glacier stops moving and end moraine will be deposited in front of it.
When a glacier stops moving forward a may be deposited?
Moraine
What is bed deformation?
The upper layers of the bed materials are deformed by the frictional drag of the overlying ice. Unconsolidated material will act like a ball bearings and allow the glacier to move forward.
What is material that moves in one large mass?
Glacier
What is glacial load?
Material (such as rock) which is carried by a glacier.
When a glacier stops moving forward what may be do sited in front of it?
Slimp
When a glacier stops moving forward what may deposited in front of it?
A mass of rocks and sediment is left as the glacier retreats, forming what is known as moraine.
The downstream end or snout of a glacier advances over periods of time during which ablation exceeds accumulation?
False
True or false When a glacier is retreating the upstream ice is still moving forward toward the downstream terminus of the glacier?
A retreating glacier is one that is diminishing more in length that its upper supply regions can compete with. The snout of the glacier is retreating, but the main body of the glacier is still moving forwards. If this situation continues, the glacier will disappear.
