Evidence for a time interval between two rock layers can include the presence of an unconformity, which indicates a gap in the geological record where erosion or non-deposition occurred. Fossil content can also provide clues; if the two layers contain different assemblages of fossils, it suggests that significant time passed between their formation. Additionally, variations in sediment type or characteristics, such as changes in color, grain size, or mineral composition, may indicate different environmental conditions over time.
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 evidence has led to the interference that solid and liquid zones exist within earth?
Evidence such as seismic waves and the behavior of earthquake waves suggest that there are solid and liquid zones within Earth. Seismic waves change speed and direction when passing through different layers of the Earth, indicating varying compositions. Additionally, the way seismic waves are reflected and refracted also points to the existence of distinct solid and liquid layers within the Earth.
What is an igneous intrusion between two sedimentary rock layers?
A laccolith is an igneous formation between two sedimentary layers
What two layers does ozone layer lay between?
The ozone layer lies in the stratosphere. It does not lie between 2 layers. Some ozone is there in troposphere.
What is a slab of volcanic rock formed when magma squeezes between layers of rock?
A sill is a slab of volcanic rock formed when magma squeezes between layers of rock. It is typically horizontal and parallel to the surrounding rock layers. Sills are distinguishable from dikes, which cut across the rock layers.
How can you protect mild steel if it is used outside?
i suggest layers and layers of cardboard
What is the p-s interval?
It is the difference in arrival time between the primary and secondary waves. Primary waves always arrive first because they have a higher velocity. The interval value is used in determining the location of an earthquake.
What can you learn from exposed layers of rock?
You learn that expose rock layers are the evidence that there was erosion and disturbances going on in that area.
What evidence from fossils and rock layers influenced Darwin ideas?
dont no

Describe the evidence used for subdividing Earth's interior into layers?
The evidence includes seismic waves, which travel at different speeds and paths through Earth's interior. By analyzing how these waves behave, scientists have determined that Earth has distinct layers such as the crust, mantle, outer core, and inner core. Other evidence comes from the study of meteorites, which provide insight into the composition of Earth's layers.
How does an angular conformity form?
Angular conformity forms when sedimentary layers are deposited over tilted or folded layers that have been eroded. The newer layers are laid down horizontally on top of the older, slanted strata, creating a distinct angular relationship between the two. This geological feature is often seen in regions where tectonic forces have altered the Earth's crust, resulting in a visible angular discordance between the layers. It serves as important evidence of geological history and processes.
What are formations that are sandwiched between layers of existing rock formations?
The formations that are sandwiched between layers of existing rock formations called sills. Another formation between layers is called laccoliths.
Scientists have discovered evidence that indicates that there have probably been ice ages before the present time.?
