Which Paleozoic rock layer is the oldest?

layer CThe principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

What are the 3 layers of rock?

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.

How old are the oldest rocks in the continental crust?

4 billion yearsEarth Observatory of Singapore The oldest oceanic crust is about 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks, which are 4 billion years old.

Which rock layer is older layer B or layer F?

Explanation: The principle of superposition states that the oldest sedimentary rock units at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A.

Is the extrusion older or younger?

Is the extrusion older or younger than rock layer B? The extrusion is younger because extrusions are always younger than the rock layers below them.

What is the oldest rock layer?

The many horizontal layers of sedimentary rock illustrate the principle of original horizontality (Figure below). The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.

What are rock layers?

Layered rocks form when particles settle from water or air. … Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata. Stratigraphy deals with all the characteristics of layered rocks; it includes the study of how these rocks relate to time.

Is the fault older or younger than rock layer A?

A fault is a break in Earth’s crust. A fault is always younger than the rock it cuts through. The surface where new rock layers meet a much older rock surface beneath them is called an unconformity. An unconformity is a gap in the geologic record.
