What else can I help you with?
How can you tell that the sandstone was not deposited on top of basalt layers?
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
What are the the layers of sandstone?
The layers of any sedimentary rock are called strata.
Is sandstone banded?
Yes, sandstone can be banded. Banded sandstone is formed when varying mineral compositions or grain sizes accumulate in layers during the sedimentation process. These layers create distinct bands or stripes in the sandstone rock.
What is sandstone characteristics?
Sandstone is much like compressed sand. It is soft and the granules will easily come off and reform sand. It is often colorful and can have many layers.
What rock is made of layers of sand?
SANDSTONE
What are the layers of sandstone called?
The layers of any sedimentary rock are called strata.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
Where was shale formed?
Shale forms in layers of sandstone or lime.
Are rocks formed in layers?
Sedimentary rocks. An example is sandstone.
When The walls of the grand canyon are made up of layers of sandstone a dike cuts across some of the layers when did the dike form?
The dike likely formed after the layers of sandstone, as it cuts across them. Dikes form when magma intrudes into existing rock layers and solidifies underground before being exposed at the surface through erosion. Therefore, the dike is a later geological event compared to the formation of the original sandstone layers in the Grand Canyon.
What is a smooth stone with layers called?
The most common smooth stone with layers is sandstone, The differently colored layers are caused as different layers of sediment build up. The Painted Dessert is one of the most spectacular examples of sandstone layers.
Where is the rock sandstone in the rock cycle?
Sandstone is a sedimentary rock that forms from the compaction and cementation of sand grains. In the rock cycle, sandstone is formed from the lithification of sedimentary deposits, eroded from existing rock formations and carried by wind or water before settling to form layers of sand. Over time, these layers are buried and compacted to eventually form sandstone.
