What might happen to a glacier that would cause the crust to float higher in the mantle?
If a glacier were to melt or retreat significantly, the weight of the ice on the crust would decrease. This would cause the crust to rebound or rise up due to isostatic rebound, a process where the Earth's lithosphere adjusts to changes in surface loads. As the crust rebounds, it would float higher in the mantle, resulting in an uplift of the land previously covered by the glacier.
What else can I help you with?
Why isn't the Earth's entire mantle liquid?
The Earth's mantle is not entirely liquid because the temperature and pressure conditions vary throughout the mantle. While the high temperatures in the lower mantle can cause some rock to partially melt and flow, the majority of the mantle remains solid due to the higher pressure that prevents complete melting.
What is a destructive force caused by the convection in the mantle?
Convection currents in the Earth's mantle are thought to be responsible for plate motions and therefore can ultimately be considered the cause of earthquakes. Mantle upwelling or mantle plumes are also thought to be the cause of hotpots which cause intra-plate volcanic activity such as that which occurs in Hawaii.
What can happen when two oceanic plates converge and one is subducted into the mantle?
When two oceanic plates converge and one is subducted into the mantle, the subducted plate melts due to the high temperatures and pressure, forming magma. This magma can then rise to the surface, leading to volcanic activity. Additionally, the subducted plate can cause earthquakes as it descends into the mantle.
Which part of valley glacier moves the fastest?
The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.
What is a destructive force caused by convection currents in the earths mantle?
Convection currents in the Earth's mantle are thought to be responsible for plate motions and therefore can ultimately be considered the cause of earthquakes. Mantle upwelling or mantle plumes are also thought to be the cause of hotpots which cause intra-plate volcanic activity such as that which occurs in Hawaii.
When does circular movement of the magna in mantle happen?
Convention cells in the molten outer core cause convection cells in the mantle.
If a glacier moved down the mountain what would happen?
Glaciers or moving, shifting and melting constantly. The worst that could happen is if too meltwater was created by the melting glacier it would cause a flood downstream.
In which layer of earth do convection current occur?
in the mantle due to the molten rock... hope this helps!!! =] also for better detail they happen in the asthenospheric mantle to
What might cause solid rock in the Earth's interior to melt and begin to flow?
The mantle cause the mantle to flow.

What does a glacier and a river have in common?
cause erosion and involveprocesses of "flow"
What are hot spots cause by?
Mantle plumes

Does the weather cause a volcano to erupt?
No because weather has no affect on the earth mantle and the mantle is the source of magma for the volcano.
What part of the earths mantle that flows and moves the plates of the earth?
Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.
How can you use the words glaciers and weathering in a sentence?
Wind and weathering can cause glacier erosion.
What change would occur in a glacier if average annual temperature rose and the precipitation decreased?
The glacier would retreat. The rise in temperature would cause the glacier itself to start melting, and in addition, would lower the amount of precipitation in the form of snow at the top of the glacier. It would be rain instead. Lowering the precipitation would cause less ice formation as well and would also contribute to the glacier retreating.
