How did glaciers form Indiana?
The Ice Age started over one million years ago and ended in Indiana about 15,000 years ago. During colder Ice Age periods, the Earth’s temperature was lower, and there was a lot of snow. Snow piled up faster than it melted, getting deeper and deeper. As the snow piled up, its weight formed into a glacier of solid ice.
Why is Indiana so flat?
Once the glaciers melted, the dirt, rocks, and sand (known as glacial till) that were picked up by the ice were all that was left behind. This till filled any hills or valleys that previously existed, leaving the land flat.
What is karst topography Upsc?
Karst Topography is the formation of landforms due to solution and deposition on any limestone or dolomitic region by the action of groundwater or surface water. Landforms and its evolution is an important segment of the Geography syllabus of the IAS Exam.
How do caves form?
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
Where do sinkholes occur?
Sinkholes have both natural and artificial causes. They tend to occur most often in places where water can dissolve the bedrock (especially limestone) below the surface, causing overlying rocks to collapse. Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania are most sinkhole-prone.
Was Indiana covered by a glacier?
