What is the law of superposition and how does it help scientists learn about earth's past?
The law of superposition states that in a sequence of undisturbed rock layers, the oldest layers are at the bottom and the youngest layers are at the top. By studying the order of rock layers and the fossils within them, scientists can determine the relative ages of the rocks and reconstruct the Earth's past environments and history.
What are horizontal layers of rocks?
Horizontal layers of rocks are rock layers that are parallel to the Earth's surface. These layers are typically formed over time through sedimentary processes, such as deposition of sediment in water or air. The horizontal orientation of these layers indicates the original horizontal position in which they were deposited.
What rocks form from layers of materials that settle and are cemented together by pressure?
Sedimentary rocks, such as sandstone and shale, form from layers of materials that accumulate and undergo compaction and cementation over time. These rocks typically contain fossils and provide important clues about Earth's history.
What layer of the earth contains rocks minerals and soil?
The layer of the Earth that contains rocks, minerals, and soil is the Earth's crust. It is the outermost layer of the Earth and is divided into tectonic plates that float on the semi-liquid layer below called the mantle.
What is the study of rock layers?
The study of rock layers is called stratigraphy. It involves examining the composition, sequence, and arrangement of rock layers to understand the Earth's history, including past environments, climates, and geological events. Stratigraphy is essential in determining the relative ages of rocks and the processes that have shaped the Earth over time.
What thing has layers?
The Earth's crust has layers, the atmosphere has layers, and certain types of cake have layers.
How do scientist learn about changes on earth from rocks?
Scientists study layers of rocks to learn about the earth and how it has changed. They know that if layers are undisturbed, the oldest rocks are on the bottom and the youngest rocks are on top. They know how old each layer is in relation to the other layers.
How were rocks used in the building of some types of castle?
Two layers of rocks (gaps in rocks filled with mortar) and earth in between the two layers of rocks.
Is the rocks layers near the surface of earth younger than rock layers further from the surface?
Yes.
What part of the earth contain rocks?
what part of the earths contains the rocks
Which two layers of the earth are made up of rocks?
Crust and mantle
What is the property of sedimentary rock?
texture as contains from ores of iron
The layers of gases that surrounds the earth and contains clouds is called the?
Atmosphere.
Does ganymede have rocks?
Yes, Ganymede does have rocks, but their exact composition is unknown. It also appears to have separate layers, similar to Earth.
What part of the earth is compose of rocks and solids?
The crust and part of the mantle is made of rocks and solids. The other layers under the earth are mostly composed of molten lava or semi-molten rocks.
What is the law of superposition and how does it help scientists learn about earth's past?
The law of superposition states that in a sequence of undisturbed rock layers, the oldest layers are at the bottom and the youngest layers are at the top.

What earth foces cause metamorphic rocks to form?
Pressure through layers of crust
