A geologist studying volcanic activity is collecting rocks that formed from hot molten magma. What type of rock is the geologist collecting?
The geologist is collecting igneous rocks, which form from the cooling and solidification of molten magma or lava. If the magma cools slowly beneath the Earth's surface, it results in intrusive igneous rocks, such as granite. Conversely, if the magma erupts onto the surface and cools quickly, it forms extrusive igneous rocks, like basalt.
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
Why cant geologist use the carbon-14 method to date igneous rock?
Geologists cannot use the carbon-14 method to date igneous rock because carbon-14 dating is effective only for organic materials, such as wood or bone, that contain carbon. Igneous rocks, formed from the cooling and solidification of magma or lava, do not contain organic carbon and therefore do not incorporate carbon-14 during their formation. Instead, geologists typically use radiometric dating methods involving isotopes of elements like uranium or potassium, which are suitable for dating the age of igneous rocks.
When a geologist studying volcanic activity is collecting rocks that formed from hot molten magma. What type of rock is the geologist collecting?
The geologist is collecting igneous rock, which forms from the cooling and solidification of molten magma. If the magma cools and solidifies beneath the Earth's surface, the rock is classified as intrusive (or plutonic) igneous rock, such as granite. If it cools quickly on the Earth's surface after a volcanic eruption, it is classified as extrusive (or volcanic) igneous rock, such as basalt.
Is it true or false that igneous rocks are classified by their oroigntextureshape?
False. Igneous rocks are primarily classified by their origin (intrusive or extrusive) and their mineral composition, rather than their texture or shape. Texture can be a characteristic used to further describe igneous rocks, but it is not a primary method of classification.

How can igneous rocks be different densities?
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
What happenes during each method to form intrusive igneous rocks?
Igneous rocks are formed under high heat conditions. Intrusive igneous rocks are formed by the crystallization of magma in the Earth's crust.
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
In a deep mine a geologist discovered a band of igneous rock cutting through some limestone bedswhat kind of rocks was that band?
The band of rock discovered would be classified as an intrusive igneous rock since it formed beneath the Earth's surface.
Rocks are classifed as?
mineral Sedimentary, igneous, or metamorphic, based on their method of formation.
Can a rock be classified as sedimentary igneous or metamorphic by its method of formation?
Yes, a rock can be classified as sedimentary, igneous, or metamorphic based on its method of formation. Sedimentary rocks form from the accumulation and cementation of sediments, igneous rocks form from the solidification of magma or lava, and metamorphic rocks form from the alteration of existing rocks due to heat and pressure.
When molten rocks cools what rocks form?
igneous rocks

What are kind of rock?
The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks. Igneous rocks cool from magma or lava. Sedimentary rocks form by the deposition of particulates and silt. Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.
