More extensive vegetation and fauna then developed and this was able to sustain a greater intensity of and likely more sedentary patterns of human activity. For this reason, this period is known informally as

Volker Ahrens the longest mountain range in the Czech Republic. Its current geomorphologic character with a steep SE fault scarp and extensive planation surfaces at the top has been influenced by long-term tectonic activity, which has uplifted the original denudational surface underlain by Paleozoic magmatic and

The studies have focused on glacial and periglacial landforms and brought new findings, also in connection with the representation of landforms so far known only from subarctic location

Franz Stuberected to modest uplift throughout the Quaternary. The Kokořín sandstone (Middle to Upper Turonian) comprises five superimposed bodies with generally high permeability and low-to-medium resistance to weathering. Most valleys are dry, shaped by occasional flash floods and gravitational processes. Disi

dscapes of the Horn of Africa are highly attractive, diverse and in a few cases unique, since they span very different environments, from highland plateaus and mountains to lowlands (even below sea level) and coastlines with a high degree of diversity and from monsoon to arid climate conditions. .T

The oldest subsurface rocks recorded offshore in southeast Sicily are Late Triassic intertidal dolomites (Gela Formation), overlain by Jurassic Black shales (Streppenosa Formation) and platform carbonate of the Siracusa Formation.
