If underground shifts in pressure increase the pressure on a magma chamber, the magma chamber may fracture and lead to a volcanic eruption. Sometimes, the remaining magma cools and crystallizes into an igneous body of granite called a pluton.
Accrual (accumulation) of something is, in finance, the adding together of interest or different investments over a period of time. It holds specific meanings in accounting, where it can refer to accounts on a balance sheet that represent liabilities and non-cash-based assets used in accrual-based accounting.
An example of an accrual is interest revenue that has been earned in one period even though the actual cash payment will not be received until early in the next period. An adjusting entry is made to recognize the revenue in the period in which it was earned.
