Why are the crystals that are on the edge of the lava flow smaller than the ones in the middle?

Because the crystals in the middle of the lava flow are small because they have a small amount of time to cool. The crystals on the edge of the lava flow are bigger because they have a longer amount of Time to cool down.

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
How fast does pillow lava flow?
Im not sure but I think its not fast but not slow so in the middle
When working in a horizontal laminar air flow hood you must work at least how many inches in from the outside edge of the work surface?
3 to 6
What is the cause of the mid-latitude westerlies?
The mid-latitude westerlies is caused by flow patterns. This pattern is known to be strong.
What is a liquid crystal?
Liquid crystal is a type of substance that has a liquid flow. However, it still retains some order in the arrangement of the molecules. Contemporary liquid crystals are used in electronic displays and items like soap.
Where would you expect to find the largest crystals in a lava flow?
You would find the largest crystals in a lava flow in the center of the flow. The largest forms of igneous intrusions are called batholiths.

What is the effect that radius changes have on the laminar flow of a fluid?
Laminar flow is the free-flowing blood in the middle of the vessel. Therefore, larger the radius of vessel, more the laminar flow. Smaller the radius of vessel, lesss the laminar flow. Laminar flow is directly reltated to the radius of a vessel.
Does heat flow cooler or smaller object?
Heat flow's from cooler objects.
Why do solid crystals of ionic compounds conduct electricity when the crystals dissolve in water?
NaCl Add water. Na + Cl - Electrons have flowed and that is all electricity is, electron flow.
What is a smaller branch of a river?
The smaller branches that flow into the main branch are called tributaries.
What unusual property do liquid crystals have when they melt?
Liquid crystals start to flow during the melting phase similar to a liquid, but they do not lose their ordered arrangement completely, as most substances do. Liquid crystals will retain their geometric order in specific directions.
What are smaller streams that flow into rives called?
Tributaries
Smaller streams or rivers that flow into larger ones?
It is a tributary
Where does the river flow the fastest in the middle or near the river bank?
The river flows the fastest in the middle of the river.
What is a smaller that flows in the river contributing to the flow and size?
a creek comes to mind
What is a stream water?
A stream is a flow of rain water that is smaller than a river.
