Which of the following provides evidence for rock formation by cooling? Select the correct answer.(1 point)
fossils in sedimentary rock
crystals in sedimentary rock
fossils in igneous rock
crystals in igneous rock
I think it's crystals in igneous rock, that's what some of the other websites said. And fossils don't really have to do with rock formation when it comes to igneous rocks from what I remember.
idk I haven't finished the test yet but I think D is correct.
also the melting temperature of bone is 3000f and the average magma temperature is 1300-2200 f
The answer is D
Well, I have to say, it's crystal clear that the correct answer is "crystals in igneous rock." When things cool down, they tend to get their act together and form orderly arrangements, like the beautiful crystals you find in igneous rocks. So, while fossils might tell you a fascinating story about ancient life, they don't provide direct evidence for rock formation by cooling. Keep your cool and go with crystals in igneous rock!
To determine which of the provided options provides evidence for rock formation by cooling, we need to understand the processes involved in rock formation.
Rock formation can occur through two main processes: sedimentation and solidification from molten material.
1. Sedimentary rocks are formed through the process of sedimentation, which involves the accumulation and compacting of sediments (such as sand, mud, and organic matter) over time. Fossils can often be found in sedimentary rocks as they preserve the remains or traces of ancient organisms. However, the presence of fossils does not provide evidence for rock formation by cooling.
2. Igneous rocks, on the other hand, are formed from the solidification of molten material, either below the Earth's surface (intrusive igneous rocks) or erupted at the surface (extrusive igneous rocks). The solidification process involves the cooling of molten material (magma or lava), resulting in the formation of crystals. Therefore, the presence of crystals in igneous rocks provides evidence for rock formation by cooling.
Based on this information, the correct answer would be: crystals in igneous rock.
