Sinkholes are circular to elliptical closed depressions commonly found in karst areas. They form when underground caves collapse due to erosion of soluble rocks such as limestone or dolomite. Sinkholes can vary in size and depth, posing potential hazards to infrastructure and human safety.

What is a circular to elliptical closed depression in karst areas?

A circular to elliptical closed depression in karst areas, often referred to as a "sinkhole" or "doline," is a geologic feature formed by the dissolution of soluble bedrock, such as limestone, due to acidic water. This process creates a depression in the landscape as the ground collapses into an underground cavity. These depressions can vary in size and depth and are characteristic of karst topography, which is marked by features like caves, springs, and underground rivers. They can pose hazards to infrastructure and ecosystems, as well as provide unique habitats.


What are all the hachured depressions called?

Hachured depressions on topographic maps are called "closed contours" or "depressions." The hachures indicate that the elevation decreases as you move inward toward the center of the contour line. These markings help to visualize areas of lower elevation, such as sinkholes or basins, distinctly from surrounding terrain.

Where marshes formed when glaciers created depressions on the Earth's surface?

Marshes formed when glaciers created depressions on the Earth's surface are called kettle ponds. These ponds are commonly found in areas where the glacial ice melted and left behind depressions that filled with water.

Are bumps and depressions in the skull closely related to how well developed the underlying brain areas are?

Bumps and depressions in the skull are more closely related to the thickness and contour of the skull bones themselves rather than the development of underlying brain areas. They can be influenced by genetics and environmental factors, but do not necessarily correlate with the development of specific brain regions.
