The member is restricted to the area about the north-eastern end of Pagodroma Gorge where it infills a chemically weathered erosion surface, cut in the form of a valley on the Permo-Triassic Amery Group. Weathering occurred during aerial exposure of the Amery Oasis in a warmer climate than...
What is the difference between weathering and erosion? What is the difference between an abyssal plain and an ocean trench? What color are contour lines on a topographic map? What are four main uses of topographic maps? How are geologic maps created?
Transportation is the movement of material across the Earth's surface by water, wind, ice or gravity. It includes the physical processes of traction (dragging), suspension (being carried) and saltation (bouncing) and the chemical process of solution. ... Transportation and weathering are the two...
What is the difference between geology and geography? Where do groundwater and runoff end up? What is the difference between weathering and erosion? How fast does most groundwater move in aquifers? What is the difference between geophysics and geology?

Human Geography The Amazon river has shaped the cultures of the surrounding human populations throughout time. The Amazon basin is home to over 30 million people. Human geography is an important factor in the Amazon river basin. Human geography affects the Amazon basin in many ways:...
One of the most common types of physical weathering iswedging. Wedging occurs when a substance finds its way into cracks or holes in rock and expands outward. This widens these cracks and holes, and can cause rock to split apart; this may also occur to exposed brick. Freezing water, crysta...
Although a majority of biologists are convinced that a mass extinction is underway on earth today, the human history with direct observatory data is too short to predict its future trends. At least five mass extinctions occurred during the Phanerozoic Eon, causing the rapid extinction of at least...
Weathering of rocks in the soil was accelerated by acid rain caused by volcanic sulphur as temperatures rose. Similar to what happened in the late Devonian, increased weathering would have led to anoxia, which blocked the streams. Climate simulations indicate that throughout that time, the oceans...
