Obsidian.
The smooth and shiny lava is called pahoehoe.
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
Smooth glassy lava is called obsidian. It forms when lava cools quickly, preventing crystals from forming, resulting in a glassy texture. Obsidian is typically black in color but can also appear in various shades of brown, green, or red.
Both pillow lava and pahoehoe lava are types of basaltic lava that form during submarine volcanic eruptions. They both have smooth, ropy surfaces, caused by the flow of lava, and are relatively low in viscosity.
Pahoehoe lava flows exhibit a fairly smooth, unfragmented, and ropy surface. This type of basaltic lava flow has a characteristic appearance due to its low viscosity, which allows it to flow and solidify in a smooth manner.

Lava that is cooler and slower-moving is called "pahoehoe." Pahoehoe lava has a smooth, rope-like or wrinkled surface texture due to its lower viscosity, which allows it to flow more easily compared to aa lava.
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.

The large smooth areas on the moon are called lunar maria. They are formed by ancient volcanic activity that filled in large impact basins with basaltic lava flows, creating the smooth surface we see today.

Fast flowing lava with low viscosity is called "pahoehoe." This type of lava has a smooth, rope-like texture and tends to move quickly across the surface due to its low viscosity, which allows it to flow easily. Pahoehoe lava often forms when basaltic magma emerges from a volcano.
Aloha: You will hear ʻā pele (rough lava) and pāhoehoe (smooth). This is (ay pay-lay and pay-hoay-hoay). Most of the time, we just say ʻā (like the letter A).
Lava with a smooth surface is known as "pahoehoe." This type of lava is characterized by its ropy, fluid texture, which results from low-viscosity basaltic lava that flows easily. Pahoehoe typically forms in slower-moving lava flows where the surface cools and solidifies while the molten lava underneath continues to move. Its smooth appearance often contrasts with the jagged texture of "aa" lava, which is more viscous and breaks apart as it flows.
