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.
by studying its features.
Geologists classify rocks by where they are formed; above ground or under ground
Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
The crystalline structure and texture.
tell me the answer I'm the one asked it
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.
Geologists can learn how a rock formed by studying its features. Two features that are especially helpful for classifying rocks are composition and texture.
- to determine the chemical nature of a rock - to determine the age of a rock by comparison
Geologists classify rocks by where they are formed; above ground or under ground
By looking at the size, shape, and pattern of the rock's grains or crystals.
Index Fossil
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;)😊
