Randomly arranged interlocking crystals and no fossils :)
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.
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
Crystals can form in all three types of rocks. Igneous rocks, like granite, form from the cooling and solidification of magma. Sedimentary rocks, such as limestone, can contain crystals that formed from precipitation of minerals in water. Metamorphic rocks, like marble, can have crystals that grew under extreme heat and pressure.
sedimentary
Both are composed of minerals. Some sedimentary rocks contain pieces of igneous rocks.
sedimentry
Igneous rock pieces can stick together through cementation to form sedimentary rocks.
No. Those are igneous rocks. Sedimentary rocks from from the acummulation and lithification of weathered material.

No. Evaporites are found in sedimentary rocks.
