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.
In both cases, great areas of land are lifted upwards to form mountains. Other mountains are formed by the earth's crust rising into a dome, or by volcanic activity when the crust cracks open. What different types of Mountains are there? There are five basic kinds of mountains: Fold Mountains (Folded Mountains) Fault-block Mountains (Block Mountains) Dome Mountains; Volcanic Mountains; Plateau Mountains; These different types of mountain names not only distinguish the physical characteristics of the mountains, but also how they were formed. Fold Mountains . Fold mountains are the most common type of mountain. The worldâs largest mountain ranges are fold mountains. These ranges were formed over millions of years. Fold mountains are formed when two plates collide head on, and their edges crumbled, much the same way as a piece of paper folds when pushed together. The upward folds are known as anticlines, and the downward folds are synclines. Examples of fold mountains include: 1  Himalayan Mountains in Asia. 2  the Alps in Europe. 3  the Andes in South America. 4  the Rockies in North America. 5  the Urals in Russia.
