Lurray Caverns in Virginia is a cavern that formed from water moving down into limestone rock below ground and forming calcite formations. This is an example of . erosion erosion Mechanical weathering Mechanical weathering water erosion water erosion chemical weathering

mechanical weathering

Explanation:

Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.

Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.

Water is an important agent of mechanical weathering, in either liquid or solid form.

Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
