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.
(b) accruals are liabilities to pay for goods or services that have been received or supplied but have not been paid, invoiced or formally agreed with the supplier, including amounts due to employees (for example, amounts relating to accrued vacation pay).
