In the case of a credit card/cash advance, there's also the convenience of not having to go through a new loan application process and having the funds almost immediately. As noted above in the government home improvement loans section, the Title 1 program also allows unsecured loans of $7,500 or less.
Intrusive Igneous Rocks. Intrusive, or plutonic, igneous rocks form when magma cools slowly below the Earth's surface. Most intrusive rocks have large, well-formed crystals. Examples include granite, gabbro, diorite and dunite. Mineral Photos courtesy of R.Weller/Cochise College.
The size of crystals in an igneous rock is an important indicator of the conditions where the rock formed. An igneous rock with large crystals probably indicates that the rock formed deep within the Earth, since it is typically warmer deep inside the Earth than near the surface. These are called intrusive rocks, and they have a phaneritic texture (from the Greek phanerous meaning visible). Similarly, a rock with small crystals probably formed at or near the surface and cooled quickly.
