Capitalization is used when an item is expected to be consumed over a long period of time. If a cost is capitalized, it is charged to expense over time through the use of amortization (for intangible assets) or depreciation (for tangible assets).
As water temperature rises, oxygen solubility decreases. On a cool summer night, a lakeâs temperature might be 60Â° F. At 100% air saturation, this lakeâs dissolved oxygen levels would be at 9.66 mg/L. When the sun rises and warms up the lake to 70Â° F, 100% air saturation should equate to 8.68 mg/L DO Â³.
Lesson Objectives. 1  Describe the factors that create lake effect snow. 2  Describe how differences in lake and air temperature relate to lake effect snow. 3  Describe weather conditions associated with the movement of frontal boundaries across the Great Lakes region. 4  Describe how hills and highlands help form clouds and precipitation. Describe how cities and industrial areas are related to lake effect snow. Background Causes of Lake Effect Snowstorms. Weather is caused by large temperature differences between the land and water. (Learn more about the Great Lakes as a heat sink and heat source in the Keeping it Temperate lesson)
