A Sill is formed when a fluid rock (usually magma but it can be mud or salt) is squeezed in between the layers (usually horizontal) of older rocks before it solidifies in place.
A Dike or Dyke is the opposite, here the fluid rock penetrates across the layering of the older rocks.
Logically to get the material to form a Sill there must be an accompanying feeder Dyke.

What type of lava does Arenal have?
Arenal Volcano in Costa Rica mainly produces basaltic andesite lava. This type of lava is characterized by its intermediate silica content, which results in a thick, slow-moving lava flow.
How can you distinguish a sill from a buried lava flow?
These extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain
What type of basaltic lava flow has a fairly smooth unfragmented ropy surface?
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.
What type of lava is thick stiff and does not flow easily?
Thick, stiff lava that does not flow easily is known as aa lava. Aa lava has a rough, blocky texture due to its high viscosity, making it difficult for the lava to flow smoothly. Aa lava typically moves in a jerky, slow manner and can form sharp, jagged edges as it solidifies.
Is dike a type of lava flow?
A dike is not a type of lava flow, but rather a sheet-like intrusion of igneous rock that cuts across existing rock layers. Dikes form when molten rock (magma) is injected into fractures in the Earth's crust and crystallizes before reaching the surface.
What type of lava flow does mt.kailauea have?
The type of lava flow that Mt. Kilauea has is a pahoehoe flow. This flow involves lava flowing into sheets after eruption. Once its top has cooled, the bottom layer moves under it resembling "a rope."

If you were trying to run away from a lava flow which type of lava would be the easiest for you to successfully run away from?
A'a Lava.

What is the difference between pahoehoe and lava?
Pahoehoe is faster moving lava and AA is slower moving lava. Both types are found in basaltic type eruptions. They have different appearances. Pahoehoe is smooth and ropey where as AA is chunky and rough.(much like top of trees) Often a pahoehoe flow can change to an AA flow depending upon the type of slope it encounters. The steeper the slope the more likely AA lava will be present. Aa has more viscosity than Pahoehoe.
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
