The majority of Earth's surface is covered in a veneer of sedimentary rock, making them the most visible surface rock.
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.
Sedimentary rocks are the most common type of rocks found at Earth's surface. They are formed by the accumulation and cementation of sediments such as sand, mud, and organic material over time. Sedimentary rocks cover about 75% of the Earth's surface.
Texture is the word used to describe a rock's constituent mineral size and arrangement, visible on a freshly fractured surface. Because a rock's surface can be weathered to a smooth or polished surface, the way it feels is not usually included in a description of texture.
Marble has visible interlocking crystals on a freshly fractured surface, and will fizz when strong vinegar is applied.

The major process of surface rock formation on volcanoes is volcanic eruptions. When molten rock (magma) from the Earth's mantle reaches the surface, it solidifies to form igneous rocks like basalt or rhyolite. Over time, repeated eruptions build up layers of volcanic rocks that contribute to the formation of the volcano.
it is a sloping layer of permeable rock sandwiched between two layers of impermeable rock and exposed at the surface.

Rock melts in the Earth's mantle, usually at depths between 50 to 200 kilometers beneath the surface. This molten rock, or magma, can rise towards the surface and solidify to form igneous rocks when it cools. The process of igneous rock formation can also occur at volcanic regions where magma erupts onto the surface.
An igneous rock forms when molten rock cools and solidifies. This can happen beneath the Earth's surface (intrusive) or at the surface (extrusive). The key factors for igneous rock formation are heat, pressure, and time.

Melting of a rock at temperatures below its melting point would not produce liquid rock below the surface. The other processes, such as increased temperature or pressure, would lead to the formation of liquid rock.
No, a rock with visible layers and no minerals is more likely to be a sedimentary rock formed from the accumulation and compaction of sediments over time. Lava hardening on the Earth's surface tends to form igneous rocks with a different texture and composition.
Granite is a coarse grained igneous rock without Pyroxene.
Intrusive igneous rock, such as granite, is formed when magma cools slowly beneath the Earth's surface. This slow cooling allows for the formation of coarse-grained crystals within the rock.
