What type of rocks are found around the jenolan caves?
The rocks around Jenolan Caves are predominantly limestone, formed from ancient marine sedimentation. These rocks exhibit distinctive features such as cave formations due to the erosion by underground water over millions of years. Additionally, there are also dolomite and shale rocks present in the area surrounding the caves.
Where can a cave be found?
Caves can be found all over the world, typically in areas with limestone or volcanic rock formations. They can be found in deserts, mountains, coastlines, and even in urban areas. Many caves are popular tourist destinations for their unique geological features.
What erosion features are associated with rivers and caves?
Both are stream-courses - though cave passages lose their streams eventually - so they display both erosion and deposits. Many erosion forms found in caves are not seen in surface water-courses, though roughly-similar meandering canyons, waterfalls, pot-holesand knick-pointsare common to both.
Where caves can be found?
Caves can be found in really any place with chemical or mechanical weathering. ++ They can but by far the vast majority of the world's caves are formed in limestone by it being dissolved by percolating water.
What are caves made of?
Caves are typically formed in rock formations such as limestone, marble, or volcanic rock. The creation of caves is primarily influenced by water erosion, chemical weathering, and geological processes over millions of years. Inside caves, various mineral deposits and formations such as stalactites and stalagmites can be found.
What are some features formed by underground erosion and deposition?
Some features formed by underground erosion and deposition include caves, sinkholes, underground rivers, karst landscapes, and stalactites/stalagmites. These formations are typically found in areas with soluble rock formations such as limestone, where water can dissolve the rock over time and create unique underground features.
How do deposition shape caves?
Deposition in caves typically occurs when minerals carried by water or formed by chemical reactions are left behind as the water evaporates. Over time, these deposited minerals can form stalactites, stalagmites, flowstones, and other cave formations. The deposition process can shape the cave by creating intricate patterns and structures, ultimately contributing to the unique features found within the cave.
Can you find gold in limestone caves?
Gold is typically not found in limestone caves. Gold is formed through geological processes such as hydrothermal deposition and erosion, while limestone is a sedimentary rock formed from the accumulation of calcium carbonate. However, gold can be found in certain types of geological formations such as quartz veins and placer deposits.
Did onyx originate from lava?
Onyx is a type of mineral formed from the deposition of calcium carbonate in caves. It is not directly formed from lava but can sometimes be found in lava tubes or caverns where it is deposited by water flowing through the rock.
What are formed when limestone found in the Earth has been eaten away?
Caves and sinkholes are formed when limestone is dissolved by underground water, creating underground spaces. Karst topography, characterized by these features, is a landscape formed by the dissolution of soluble rocks like limestone.
Can limestone be found in caves?
It's found around them! The vast majority of the world's caves are formed in limestone (soluble in ground-water).
What are two types of features that result from wind desposition?
Dunes and loess are two types of features that can result from wind deposition. Dunes are mounds of sand formed by wind action, while loess is a type of fine-grained sediment deposited by the wind and often found in extensive blankets.
What type of rocks are found around the jenolan caves?
The rocks around Jenolan Caves are predominantly limestone, formed from ancient marine sedimentation. These rocks exhibit distinctive features such as cave formations due to the erosion by underground water over millions of years. Additionally, there are also dolomite and shale rocks present in the area surrounding the caves.
Which types of weathering and erosion are primarily responsible for the formation of caves?
Caves are primarily formed by a combination of chemical weathering, particularly from acidic groundwater dissolving limestone or other soluble rocks, and erosion from flowing water that carves out the cave over time. Both processes work together to create the unique features found in caves.
What are the names of some specific lowland features that are found among the highlands of the country?
Some specific lowland features found among highlands include valleys, basins, plains, and floodplains. These features are typically characterized by lower elevation compared to the surrounding highlands and are often formed by the erosion and deposition of material by rivers and glaciers.
What are wavy features found on some sandstone?
Those are deposition layers influenced by wind or moving water.
What is a ridge formed by deposition of till called?
A ridge formed by deposition of till is called a moraine. This type of ridge is typically found in regions where glaciers have advanced or receded, leaving behind a mixture of sediment and rocks.
