What are the three main categories into which geologists classify rocks?

The three main categories into which geologists classify rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed from the accumulation and lithification of sediments. Metamorphic rocks are created from the alteration of pre-existing rocks due to high temperature and pressure.


Why are sedimentary rocks so important for understanding the history of the Earth?

Through observation of sedimentary rocks, geologists are able to analyze rock layers and date the rocks by testing the carbon in each sample.


How do geologist classify sedimentary rocks?

They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.


What do you call people that study rocks?

I believe they are called Geologists.


What type of rock is most useful historical geologists?

Sedimentary rocks are most useful for historical geologists because they can contain fossils and provide information about past environments and the Earth's history. Sedimentary rocks also often preserve layers that can be used to determine the relative age of rock formations.


Why do scientists look to sedimentary rocks when studying the history of the Earth?

The vast majority of fossils are found in sedimentary rock.


Why do BP geologists look for oil and gas where they find sedimentary rocks?

BP geologists look for oil and gas in sedimentary rocks because these rocks are typically formed in environments that can trap organic materials, which over time can transform into hydrocarbons. Sedimentary basins often provide the right conditions for the accumulation and preservation of organic matter, along with the necessary heat and pressure to convert it into oil and gas. Additionally, the porous and permeable nature of certain sedimentary rocks allows for the storage and movement of these hydrocarbons, making them ideal reservoirs for extraction.


Rocks formed from weathered debris from preexisisting rocks are called?

They are called clastic sedimentary rocks.


Most sedimentary rocks are readily dated by radiometric methods True False?

False. Most sedimentary rocks cannot be directly dated by radiometric methods because they are composed of sediments that were already eroded and transported from existing rocks. Instead, geologists use relative dating techniques to determine the sequence of events in which sedimentary rocks were formed.
