karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.
Which of the following features are indicative of a landscape defined by karst topography?
Which of the following features are indicative of a landscape defined by karst topography? sinkholes. solution valleys. Karst topography can be identified even when looking at a topographic map.
Does groundwater move faster through sediment with large pore spaces?
Distribution and Movement of Water Underground Groundwater moves faster through sediment with large pore spaces than through sediment with small pore spaces.
What is a Dripstone feature that forms on a cavern ceiling?
Two of the most common dripstone deposits are stalactites and stalagmites. Stalactites form like icicles as minerals slowly precipitate minerals on the ceiling. Stalagmites grow upward from the cave floor where the drops of water land.
Which features are usually associated with karst topography?
Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.
What are the features of karst topography?
Features of karst landscapes include caves, springs, disappearing streams, dry valleys, and sinkholes. Acidic groundwater moves through fractures and spaces within the rock, slowly dissolving and enlarging spaces to create larger openings and connected passages.
Why does karst topography only exist in some geographic locations apex?
Why does karst topography only exist in some geographic locations? Most regions do not have limestone under the soil. Which is missing in most areas that do not have Karst topography? Limestone.
Is sand or silt more porous?
Sand is the largest mineral particle and it has more pore space between its particles than silt or clay.
What is mostly caused by rapid snowmelt and storms?
Besides flooding, rapid snowmelt can trigger landslides and debris flows. In alpine regions like Switzerland, snowmelt is a major component of runoff. In combination with specific weather conditions, such as excessive rainfall on melting snow for example, it may even be a major cause of floods.
Why do caverns form in the zone of saturation?
The formation of caverns takes place in the zone of saturation. They are formed in carbonate and sulfate rocks ( limestone, dolomite, marble, gypsum) by the action of groundwater movement which dissolves the rock to form tunnels.
Which features are usually associated with karst topography Brainly?
Answer: Features of karst landscapes include caves, springs, disappearing streams, dry valleys, and sinkholes.
How is karst topography divided into macro and micro?
Karst topography Karst topography is divided into macro topography and micro topography. Von Engeln[1]defined the conditions supporting formation of topography karst: Soluble and near surface Massif, thick, and buried Medium to high accumulation rainfall
What makes karst a unique type of terrain?
Karst is terrain in which soluble rocks are altered above and below ground by the dissolving action of water and that bears distinctive characteristics of relief and drainage. Karst has unique hydrology condition, this condition is caused of karst composed of soluble lithology and the lithology has good condition in secondary porosity.
How are losing streams common in karst landscapes?
Losing streams are common in two types of landscapes, arid areas, and karst areas. In karst areas, a sinking river results when a river disappears through a ponor or sink-hole on the karst landscape. Thereafter, it flows through an underground cave system where it becomes a subterranean river.
Where are the karst features found in Ireland?
Turloughs are karst features that are unique to Ireland and are found west of the River Shannon in Ireland. A turlough is a disappearing lake found in a limestone area. Basically, the area to the west of the Shannon River comprises of pure limestone with little glacial drift cover.
