Fossil. The mere word kicks most people’s imagination into high gear. It mostly evokes dinosaurs, of course—the stars of the Mesozoic era. And yet, because those famous reptiles are already the focus of many other books, in this book we will discuss different but no less fascinating kinds of animals: the ones that many people refer to incorrectly as “marine dinosaurs.

This book discusses new insights concerning the influence of the climate upon the earth’s relief, in particular upon the continents. It has been found that this climatic, this exogenic influence is much stronger than any endogenous influence. Endogenous forces, as any geologic map will show, are distributed randomly over the entire earth, while the exogenic influence of climate follows strict rules in its distribution from the pole to the equator, both today as in the past. Their distribution and intensity make climatic influences the best basis upon which to found a system of geomorphology, such as the one presented here.

Earth is a very small part of a vast universe, but it is our home. It provides the resources that support our modern society and the ingredients necessary to maintain life. Knowledge of our physical environment is critical to our well-being and vital to our survival. A basic geology course can help a person gain such an understanding, and can also take advantage of the interest and curiosity many of us have about our planet—its landscapes and the processes that create and alter our physical environment.

Книга о географических наэваниях гор Урала от северных отрогов Пай Хоя до теряющихся в каэахстанских степях Мугоджар.

Why do earthquakes, volcanoes, floods, and landslides happen? What causes mountains to rise? How do beautiful landscapes develop? How have climate and life changed through time? When did the Earth form, and by what process? Where do we dig to find valuable metals, and where do we drill to find oil? Does sea level change?

Зубчатой стѣной встаетъ на границѣ Европы и Азіи Уральскій горный хребетъ. Въ особенности представляется онъ такою стѣною, когда подъѣзжать къ нему съ востока, изъ западно-сибирскихъ степей. Уже издали видна тогда зазубренная горная цѣпь, тянущаяся по западной сторонѣ горизонта съ сѣвера на югъ.

Magnetism is one of the most pervasive features of the Universe, with planets, stars and entire galaxies all having associated magnetic fields. All of these fields are generated by the motion of electrically conducting fluids, via the so-called dynamo effect. The basics of this effect are almost trivial to explain: moving an electrical conductor through a magnetic field induces an emf (Faraday’s law), which generates electric currents (Ohm’s law), which have associated magnetic fields (Ampere’s law). The hope is then that with the right combination of flows and fields the induced field will reinforce the original field, leading to (exponential) field amplification <...>
