State-level data show the difference in crude oil API gravity in different parts of the country. For example, oil produced in Texas has a relatively broad distribution of API gravities, with most production ranging from 30â50 degrees API. Oil produced in North Dakota tends to be light (less dense).
Margot Frank, Anne's older sister, died of typhus in Belsen at the age of 19 in March 1945 (Exact date unkown).
