Why can't geologists use rocks from earth to learn how long ago earth formed?
Geologists can't use rocks from Earth to determine the planet's age because those rocks have all been recycled through the rock cycle over time. This means that the original rocks from when Earth formed no longer exist. Instead, geologists use radiometric dating of rocks from Earth's surface to estimate its age.
How do geologists classify igneous rock?
Geologists classify igneous rocks based on their mineral composition, texture (grain size and arrangement of crystals), and overall chemical composition. Igneous rocks are further categorized as intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface) based on where they solidified.
What clues tells geologists how extrusions are formed?
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
When geologists place rocks in their proper sequence of formation this is called dating?
No, when geologists place rocks in their proper sequence of formation, it is called relative dating. This method does not give an exact age, but it establishes the order in which rocks formed based on their position in a sequence. Absolute dating techniques are used to determine a specific numerical age of a rock or fossil.
How can geologists determine how a rock was formed?
Rocks and minerals are tested to discover their age, how they were formed, and what they are made of. Mining and energy exploration companies rely on this information in order to make decisions on investments and revenues involving billions of dollars. Academically, the study and testing of rocks and minerals adds to the base of scientific knowledge which has a multitude of uses to governments, businesses, and individuals.
Geologists determine the absolute age of rocks using?
Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.
How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
How do geologists learn how a rock formed?
Geologists study the rock's mineral composition, texture, and structure to determine how it formed. They also consider the rock's surroundings and the geological processes that may have been involved in its formation, such as volcanic activity or sedimentary deposition. By analyzing these factors, geologists can piece together the rock's history and understand how it was created.
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.
What do geologists have now that they didn't have 60 years ago?
Portable spectrometers used to determine what minerals are in an area of interest. Metal detectors. Much more knowledge about how the Earth formed.
How geologists believe central America was formed?
climate and mountains

How do geologists believe the great lakes were formed?
Geologists believe the Great Lakes were carved from glaciers that crossed over the area thousands of years ago.
What clues does extrusion tell geologists?
Geologists study where intrusion and extrusion formed in relation to other rock layers. This helps geologists understand the relative ages of the different types of rock! Hope it helps;)😊
What is the s and p time method in science?
The S-time method in science is a technique for determining the relative ages of rock layers by observing the sequence in which they were formed. The P-time method involves using radiometric dating to determine the absolute age of rocks based on the decay of radioactive isotopes. Together, these methods help geologists understand the chronology of Earth's history.
