Caves

Welcome to the web site of Susan Lawrence. In this web you will find an introduction of Caves. It will discuss the four types, Tube Cave, Sea Cave, Sandstone Cave, and Limestone Cave. There will be a lesson plan for discussing these caves.

There are many caves found in Arkansas. Most are considered to be limestone. One such cave is Blanchard Springs Caverns found in the Ozark Mountains. If you enjoy caves, you owe yourself a trip to it. While going through a tour of this cave, you need to use your imagination.

You could pretend to be having a bacon sandwich
as you pass the wall that looks like bacon hanging from the wall.

Cave A

As you tour further, you might imagine that you once sailed on the Titanic.
Setting right at the top of the wall is a ship.

Cave B

Last, you might want to visit the largest soda fountain shop in the world.

Cave C

All these sights can be seen while visiting the cavern.

A cave is a natural hole or passageway found deep inside the earth. They range in size from just big enough to hold one person to many miles of underground rooms. Underground rivers and streams can also be found there. Most that have been discovered and explored have been developed in order to allow the outside world to experience these natural wonders deep inside the earth.

One type of cave is a Lava Tube. These caves form in layers of rocks around volcanoes. As volcanoes erupt, hot lava flows down onto the earth. As the lava flows and cools, it may form a pipe or tube around the hotter flow. When the erupting stops, the cooled lava is left in the form of solid rock, forming a tunnel or tube.

Sea Caves are formed when powerful ocean waves crash against cliffs along the ocean shore. The waves carve out the caves by wearing away the loose parts of these cliffs. Caves are formed at the foot of these cliffs. Sea Caves are homes for many types of sea animals. These shallow pools provide homes for starfishes and crabs. Seals and sea lions also enjoy using the rocky ledges for a safe place to rest.

Sandstone Caves took millions of years to form. What is now dry land, used to be covered with water. Sand on the bottom of the sea became pressed together and pushed upward. Water from the sea flowed away as this happened causing large canyons to form in the cliffs. Over the years, moving water carried the loosened sandstone away forming the large holes or caves inside the cliffs. These large caves were once homes for many different tribes of people.

Limestone caves were formed in much the same way as sandstone caves. Small animals that lived in the sea died. Their shells and skeletons sank to the bottom of the sea. Over the years, the animals’ remains began to build up causing layer after layer to be cemented together. These layers were pushed upward out of the sea. The weather and chemicals in the water acted on these layers causing limestone to form. Water running down into the limestone for years and years, washed it away causing great holes or caves to be left.

Arkansas is full of limestone caves. Blanchard Springs Cavern, found in the Ozark Mountains, is a good example of a limestone cave. Open now to the public, you get a wonderful view of the natural wonders deep inside the earth and can also experience the sound of the running water which helped to form the cave many years ago.
