For at least the last 100 years, sea level has been rising at an average rate of about 1.8 mm (0.1 in) per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper 500 metres (1,640 feet) of sea water.recise determination of a mean sea level is a difficult problem because of the many factors that affect sea level. Sea level varies quite a lot on several scales of time and distance.
Depreciation is very much necessary for fixed assets because the fixed asset would lose its residual value due to the wear and tear, depletion, passage of time, obsolescence or accidents over a time period. Therefore, the actual value of the asset cannot be determined if we take the purchase amount in the books every year.
Depreciation Defined. Depreciating an asset means allocating the asset's cost over its useful life. The useful life of an asset, or economic resource, is the period of time over which a company intends to use this asset in operating activities or manufacturing processes. Funded Depreciation Defined. Funded depreciation is a fixed asset management method that helps a company set aside funds to renew machinery and equipment that it uses in operating activities. For instance, a company buys a new truck valued at $100,000 and records $10,000 in annual depreciation expense over 10 years.
