No, a rock with visible layers and no mineral crystals is unlikely to have formed from lava. Such characteristics are typical of sedimentary rocks, which are formed from the accumulation and compaction of sediments. In contrast, igneous rocks that form from lava usually contain visible mineral crystals or a glassy texture due to rapid cooling. Therefore, the rock in question is more likely to be sedimentary rather than igneous.
No, a rock with visible layers and no mineral crystals likely did not form from lava hardening on Earth's surface. Such layered rocks are typically sedimentary, formed from the accumulation and compaction of sediments over time. In contrast, igneous rocks formed from lava cooling often contain visible mineral crystals, as the cooling process allows crystals to grow.
The rock described is likely a type of sedimentary rock rather than igneous, as it has visible layers and lacks mineral crystals. Sedimentary rocks typically form from the accumulation and compaction of sediments, which can include materials such as sand, silt, and organic matter. If the rock formed from lava hardening on the Earth's surface, it would typically be classified as an igneous rock, such as basalt, which usually contains mineral crystals. Therefore, a rock with visible layers and no crystals suggests a sedimentary origin rather than a result of lava cooling.
Large mineral crystals are commonly found in igneous rocks, such as granite and pegmatite, where slow cooling allows minerals to grow large. Certain metamorphic rocks, like marble and schist, can also contain large mineral crystals due to high pressures and temperatures. Veins and pockets within rocks can sometimes host large crystals as well.
A rock with visible layers and no mineral crystals is unlikely to have formed from lava hardening on the Earth's surface. Such characteristics suggest sedimentary processes, where layers accumulate over time from sediments being deposited and compacted. In contrast, igneous rocks formed from lava typically have a more crystalline texture, as minerals crystallize during the cooling process. Therefore, the rock in question is more consistent with sedimentary formation rather than igneous.

The rock shown is likely composed of large crystals that were formed by slow cooling inside the Earth's crust, allowing mineral grains to grow to a visible size. This process typically occurs in intrusive igneous rocks like granite or pegmatite.
An igneous rock with small, barely discernible crystals most likely formed from the rapid cooling of magma or lava, typically at or near the Earth's surface. This quick cooling process prevents large crystals from developing, resulting in a fine-grained texture. Such rocks are commonly classified as basalt or rhyolite, depending on their mineral composition.
Yes, a rock with visible layers and no mineral crystals likely formed from lava hardening on Earth's surface, typically classifying it as a type of sedimentary rock rather than an igneous rock. The layered appearance suggests that it may have been deposited in a series of sedimentary events, rather than solidified from molten lava, which generally forms crystalline structures. This type of rock could also result from volcanic ash or other materials settling in layers.
An igneous rock that formed extremely slowly underground would likely have a fine-grained texture with small mineral crystals. This slow cooling process allows for the minerals to grow larger and more interlocking, resulting in a strong and dense rock with no visible grains or pores.
No, rock with visible layers and no visible mineral crystals is likely to be sedimentary rock, formed from the accumulation and consolidation of sediments like sand, mud, or organic material. Rocks formed from lava hardening on the Earth's surface, like basalt, tend to have a uniform texture and lack visible layers due to the rapid cooling process.
It is most likely extrusive.
An igneous rock with very small mineral crystals most likely formed from a rapid cooling process. This rapid cooling prevents the minerals from growing larger, resulting in the fine-grained texture characteristic of rocks like basalt or rhyolite.
