How do mountain glaciers and continental glaciers differ in terms of dimensions, thickness and patterns of movement?
tester [92]

How do mountain glaciers and continental glaciers differ in terms of dimensions, thickness and patterns of movement?

Answer:
<span>
Continental glaciers are thicker, much more expansive sheets. Mountain glaciers flow downhill as a result of gravity acting on the mass of ice. Continental glaciers move in response to pressure from the weight of material in their thick midsections.

basball momentum

pball=mball x vball

=0.142 x v

p_bus = pball

18200 x 16.5 = 0.142 x v

v=(18200 x 16.5)/0.142

v is the answer for baseball
