The famous Matterhorn in Switzerland displays three types of glacial erosion: 1  Cirques are created when glaciers erode the mountainside, scouring into it and creating rounded hollows with steep uphill faces, shaped like tilted bowls. 2  ArÃªtes are jagged, narrow ridges created where the back walls of two glaciers meet, eroding the ridge on both sides.
Interest Rates for Federal Student Loans. Federal student loans have interest rates ranging from 5 percent to 7.9 percent, with the standard being 6.8 percent. Interest rates are normally fixed for the lifetime of a loan; even though rates are re-evaluated by Congress every few years, the interest rates on your existing loans should not be affected.
If you want to get a lower interest rate, you need to first figure out what your current rates are. Interest rates on federal student loans can range from just under 4% to over 7%, depending on the type of loan. Private student loan rates can be even higher, averaging around 9% to 12%. When you refinance your loans, you replace existing student loans with a new one. This gives you a chance to shop for a lower interest rate. The higher your current interest rate, the more youâll benefit from refinancing to a lower rate.
