What causes a geode to be hollow or solid?
A geode starts out as basically a cavity or pocket in otherwise solid rock. The cavity walls grow inward as mineral crystals grow from solutions that seep into it. In time, the cavity may become completely infilled with mineral crystal. The geodes that are found on the surface are survivors of weathering which eroded the rock in which they were once emplaced. This is because the geodes are composed of minerals such as quartz which are more resistant to erosion than the rocks which originally surrounded them.
How does forming in a restrictef space affect the structure of a crystal?
Indeed, not all crystals are perfect. Often a process called twinning occurs. On the walls of a cavity, there may be several nucleation centres, points of first formation of a crystal. As these crystals grow they will interfere in each other's space.

Why are foam filled cavity walls are better than air filled cavity walls in reducing heat loss?
Foam is a good insulator- this means that it traps still air and prevents heat travelling and being lost. Heat is lost more easily through the air in air-filled cavity walls as the air is not kept still.
Why the walls of houses often are filled with insulatio?
This is so heat (or AC air) will stay in.
Why are the walls of houses often filled with fiberglass?
I think it has something to do with maintaing the temperature in the home. Ventilation. Also, it prevents humidity from destroying the interior of walls.
Will refreezing meat affect the taste?
Yes it will cause Ice crystals to form on the cell walls of the meat, and degrade taste.
When were filled cavity walls a requirement of the building regulations?
after they realized that entire block walls would collapse in high winds when they didn't fill the cells around the window and door openings
Could the pool liner being stretched cause it to pull on the walls causing the walls to bow in three spots even though the pool looked level when it was filled?
Absolutely not. Only hydrostatic pressure caused by ground water can cause vinyl liner pool walls to bow. By keeping the pool filled to no less that two feet from the top, year round, can this be prevented.
Destruction of the walls of the alveoli producing abnormally large air spaces that remain filled with air during exhalation?
Emphysema
What is the surface-facing cell walls of epidermal cells filled with to prevent water loss?
They are covered with keratin.It is a water proof protein.
How do you remove the gunnite surface from around a pool that has been filled in?
You have to remove the water or the land fill in order to work on the walls of the vessel.
