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.
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
The law that states the oldest layers of sediment will be located on the bottom is called the Law of Superposition. This principle is fundamental in understanding the relative ages of rock layers in geology.
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.
The oldest fossils are typically found in the deepest sedimentary rock layers, which are located at the bottom of a rock formation. This principle is known as the law of superposition in geology, where older rock layers are found beneath younger ones.
The oldest rock layer in a canyon is typically the layer found at the bottom. This is because new layers of rock are deposited on top of older layers over time, resulting in a sequence with the oldest rocks located at the base of the canyon. Geologists use principles of stratigraphy, such as the Law of Superposition, to determine the relative ages of rock layers in a canyon.
The shale layer is the youngest in the series. In undisturbed rock layers, the Law of Superposition states that the youngest layer is on top and the oldest is at the bottom. So, in this case, the limestone would be the oldest layer, followed by sandstone, and then shale.
The oldest organisms can generally be found in the lower layers of rock, as these layers were formed earlier than the upper layers. By examining the relative positions of different rock layers, scientists can determine the ages of the organisms found within them.

The layers of any sedimentary rock are called strata.

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.
Erosion removed the youngest layers of rock, but all the rock is sandstone.
The oldest layers of sediments are typically found at the bottom of a sedimentary rock sequence, with the youngest layers at the top. Over time, new layers of sediments accumulate on top of older layers, creating a chronological sequence with the oldest layers at the bottom.
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.
The law that states the oldest layers of sediment will be located on the bottom is called the Law of Superposition. This principle is fundamental in understanding the relative ages of rock layers in geology.

The youngest rock is typically found on top in a sequence of rock layers due to the principle of superposition, which states that younger rocks are deposited on top of older rocks. This means that the oldest rock is usually located at the bottom of a sequence of rock layers.
