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.
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.
Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
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.

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.

They are called intrusive igneous rocks, characterized by their visible mineral crystals.
Igneous rocks that have mineral crystals easily seen with the unaided eye formed from slow cooling and crystallization of magma deep underground or at the Earth's surface. The slower the cooling process, the larger the mineral crystals can grow, resulting in rocks like granite and diorite with visible crystals.

Granite is an igneous rock with visible mineral crystals.
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.

Rocks with visible crystals are classified as crystalline rocks. These rocks are formed when minerals inside the rock crystallize and grow to a size that they are visible to the naked eye. Examples include granite and basalt.
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.
Yes, gabbro is a coarse-grained igneous rock made up of larger crystals visible to the naked eye. These crystals are usually a combination of minerals such as plagioclase feldspar, pyroxene, and sometimes olivine.
