What is the significance of the varangian glaciation?
The Varangian Glaciation occurred during the Neoproterozoic Era. It is significant because there are deposits found on almost every continent, and deposits are found interbedded with marine limestones. This indicates a mass glaciation which affected even low altitudes. Glaciation was caused by the distribution of the continents. All the continents were situated at low latitudes with open oceans at the poles, a configuration that has never happened since.
Compaire and contrast ranching and pastoralism?
Although both are forms of extensive grazin, there are some differences: while pastoralism is mainly related to extensive grazing by a community or group of any land under communal ownership, ranching means private ownership. Pastoralism is a more nomadic form, mainly without commercial goals.
How are a bird and crocodile homologouse?
Both species offer parental care to their offspring.
What was the ordovician-silurian extinction?
It was the second largest extinction in terms of loss of life. The extinction was caused by the movement of Gondwana into the south polar region which led to glaciation and subsequent sea level fall. At this time all know life was confined to the oceans and 60% of marine invertebrates died. The event ended when Gondwana moved out of the south polar region, the glaciers melted, and sea level returned to normal.
What are the major geologic events in the Permian period?
During the Permian period, major geologic events included the assembly of the supercontinent Pangaea, significant climatic changes leading to glaciation and warming events, and massive volcanic activity resulting in the formation of the Siberian Traps. These events had significant impacts on biodiversity and led to the largest extinction event in Earth's history, known as the Permian-Triassic mass extinction.

What is the name of the period that followed extensive glaciation in the precambrian?
The period that followed extensive glaciation in the Precambrian is called the Proterozoic Eon. This period was characterized by the development of complex life forms and the formation of supercontinents.
An extensive late Paleozoic glaciation affected southern India southern Africa and southeastern South America?
An extensive, late Paleozoic glaciation affected southern India, southern Africa and southeastern South America.
When was The Varangian Way created?
The Varangian Way was created in 2006-11.
Where did the varangian route run?
The Varangian Route runs NW (north west).
Which would be likely to occur in a region of continetal glaciation but not in a region of valley glaciaton?
The presence of large ice sheets covering extensive land areas would be likely in a region of continental glaciation. This type of glaciation is characterized by vast ice sheets that spread over entire continents, unlike valley glaciation which occurs in mountain valleys and is more localized in scope.
When did the last glaciation happen?
The last glaciation, known as the Last Glacial Maximum (LGM), occurred approximately 20,000 years ago during the Pleistocene epoch. It was a period of extensive ice coverage and cooler temperatures compared to the present day.
What is pleistocene glaciation?
The Pleistocene glaciation refers to a series of ice ages that occurred during the Pleistocene epoch, lasting from about 2.6 million to 11,700 years ago. It was characterized by multiple advances and retreats of ice sheets covering large parts of the Earth's surface, leading to the formation of glaciers, ice caps, and extensive ice sheets. The glaciation had a significant impact on global climate, topography, and biodiversity.
How did the ice age end?
Well for one thing, it didn't. The definition of Ice Age is a period of extensive glaciation with brief interglacials between the points of highest glaciation. By that definition we're are still in the middle of an ice age, a warm bit of one, but still in one. If we weren't in an Ice Age there would be no glacials, whatsoever.
Which would be likely to occur in a region of continental glaciation but not in a region of valley?
The presence of large moraines (deposits of glacial till), erratic rocks (boulders carried by glaciers), and drumlins (elongated hills formed by glacial action) would be more likely in a region of continental glaciation compared to a region of valley glaciation. The larger scale and extensive coverage of ice in continental glaciation are responsible for shaping the landscape in these ways.
The Russian trade route was called the .?
This trade route was known as the Varangian Route. The Route connected Europe to Asia through the Russian territory.
What term name is a process by which moving masses of ice change the topography of a region?
Glaciation
