Recent humanization development of physical geographical studies in the USA and Europe is reviewed mainly based on The Changing Nature of Physical Geography by Derek Gregory.

Instead ， he discovered that the documentations made by his predecessors in their geographical studies were quite unreliable in many aspects.

相反，他发现了前人在文献中记述的地理研究有很多谬误偏差。

Small planets close to their parental stars risk becoming tidally locked: that is, the lengths of their days come to match their orbital periods, and they thus have one permanently hot hemisphere and one that is permanently cold.
