Skyblock is a minigame in the sandbox video game Minecraft. [citation needed] The original minigame consists of a small island floating in the air, on which a player must survive on, [1] although the gameplay and rules may vary. [2] It was originally created by a user going by the name Noobcrew in 2011, and subsequently published to ...
Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk .
For example, one large glacial erratic in Germany measures 3 by 6 km (2 by 4 mi) and is 9 m (30 ft) thick. [10] Near Cooking Lake, Alberta , one of several large glacial erratics, which is called the Cooking Lake (Number 6) megablock , covers an area of at least 10 km 2 (4 sq mi), has a length of 4.0 km (2.5 mi) and is about 10 m (33 ft) thick.
Till is a form of glacial drift, which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. [1] It is distinguished from other forms of drift in that it is deposited directly by glaciers without being reworked by meltwater.
Usually the mines are said to contain valuable elements or minerals such as gold, silver or diamonds. Often there is a map or other document allegedly detailing the history or location of the mine. Common to all the lost mine legends is the idea of a valuable and mysterious resource being lost to history.
Many glacier caves are relatively unstable due to heat transportation and glacial motion, and are subject to localized or complete collapse, as well as elimination by glacial retreat. An example of the dynamic nature of glacier caves is the former Paradise Ice Caves, located on Mount Rainier in the United States. Known since the early 1900s ...
Gravel pits are located where there are rich sources of materials suitable to be crushed into aggregate, often at sites of fluvial, glacial, or floodplain geological deposits. [4] Sedimentary and igneous rocks typically produce good quality aggregates of various sizes, but metamorphic rocks are rarely mined at gravel pits as they tend to have ...
Glacial plucking both exploits pre-existing fractures in the bedrock and requires continued fracturing to maintain the cycle of erosion. [4] Glacial plucking is most significant where the rock surface is well jointed or fractured or where it contains exposed bed planes, as this allows meltwater and clasts to penetrate more easily.
