In general, you should aim to keep your spending far below 30 percent of your credit limit. In other words, if you're spending $1,500 or less a month using a card with a $5,000 limit, you're OK -- though the highest credit scores go to those with spending levels below 10 percent of their limit.
An active dike is a body of magma moving through a sheet-like, vertical or nearly vertical fracture. An important aspect of magma flow not dealt with in the gelatin activity is the heat lost during eruption. Magma, ascending as a dike begins to cool and solidify and the flow may become localized in the dike.
The answer is Dike. In Geology, Dike is a sheet of rock formed in a fracture in a pre-existing rock body. Magmatic dikes are formed when magma intrudes into a crack then crystallize. It is an igneous body with a very high aspect ratio.
