What was the idea of rock evidence?
Rock evidence refers to the geological clues that help scientists understand Earth's history, such as how different rock layers were formed, what types of organisms lived in the past, and how the Earth's surface has changed over time. By studying rock evidence, scientists can reconstruct past environments and events that have shaped the planet.
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 do you use rock layers in a sentence?
Those rock layers are quite colorful.
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.
How do you know that the fault is the youngest feature in the rock body?
A fault is considered the youngest feature in a rock body because it displaces the surrounding rock layers, indicating that it occurred after those layers were formed. Geologists use principles such as superposition and cross-cutting relationships to determine the relative ages of geological features. If a fault cuts through other rock layers, it must be younger than those layers. Additionally, any sediment or material that accumulates in the fault zone itself can provide further evidence of its relative youth.
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
Where is most fossil evidence found?
Fossils are found most commonly in layers of sedimentary rock. This type of rock begins to form when water and wind form layers of sand and silt.
How can you explain the evidence that different rock layers are exposed at river level at these two sites?
mierda

How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
What are the three examples of changes in life that are supported by evidence of rock layers?
sedimentary, igneous, metamrphic -con
What would be the best evidence to support a theory that rock layers from different areas are the same age?
geologic colums

Are Aquifers rock layers?
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
Which type of rock provides the best evidence that Earth's environment has changed over time?
Sedimentary rock provides evidence of the different changes in the earth's environments. Evidence is deposited in layers which have characteristics of wet, dry, hot or cold climates.
What does it mean for rock layers that are forming?
Rock layers that are forming are stratifying.
