Source sentences:
text: The curve illustrates what is known as the flow law or constitutive law of ice: the rate of shear strain is approximately proportional to the cube of the shear stress.
text: Because ice can flow faster where it is thicker, the rate of glacier-induced erosion is directly proportional to the thickness of overlying ice.
text: An ice surface in fresh water melts solely by free convection with a velocity that depends linearly on the water temperature, T ∞ , when T ∞ is less than 3.98 °C, and superlinearly when T ∞ is equal to or greater than 3.98 °C, with the rate being proportional to (T ∞ − 3.98 °C)α, with α = 5/3 for T ∞ much greater than 8 °C, and α = 4/3 for in between temperatures T ∞ .
