In the hypothesis testing approach of Jerzy Neyman and Egon Pearson, a null hypothesis is contrasted with an alternative hypothesis, and the two hypotheses are distinguished on the basis of data, with certain error rates. Proponents of each approach criticize the other approach.
In geography, relief refers to the highest and lowest elevation points in an area. Mountains and ridges are typically the highest elevation points, while valleys and other low-lying areas are the lowest. Relief is essential to understanding the topography of an area.
Fault Block mountains or Horst- formed when colliding plates build up pressure along parallel cracks (faults) in the Earth's surface. The extreme pressure causes large blocks â¦of land to slip and be uplifted. Elevations are normally greater than 3000 meters above sea level. Example: The Sierra Nevadas of California.
